Field of the Invention
The present invention, in general, relates to the field of optical communication systems. More particularly, the present invention provides an access system with high subscriber density in passive optical networks (PON) using single mode optical fiber.
Background of the Invention
Passive Optical Networks (PONs) are an emerging broadband, multi-services, and access technology allowing the benefits of fiber optic transmission to be pushed closer to the user direcdy at the user's premises. A PON typically consists of a central office node, called an optical line terminal (OLT), one or more user nodes, called optical network units (ONUs) or optical network terminals (ONTs), and the fibers and splitters between them, called the optical distribution network (ODN). The ONUs typically connects via VDSL or Ethernet to the users premises for speeds up to 100 megabits. An ONT is a single integrated electronics unit that terminates the PON and presents native service interfaces to the user. An ONU is the PON-side half of the ONT, terminating the PON, and may present one or more converged interfaces, such as xDSL or Ethernet, toward the user. An ONU typically requires a separate subscriber unit to provide native user services such as telephony, Ethernet data, or video.
The OLT provides an interface between the PON and backbone network. The interfaces typically include Internet Protocol (IP) traffic over Gigabit, 10G, or 100 Mbit/s Ethernet, standard time division multiplexed (TDM) interfaces such as SONET/SDH or PDH at various rates, and ATM UNI at 155-622 Mbit/s. The ONT terminates the PON and presents native service interfaces to the user. These services can include voice (plain old telephone service (POTS) or voice over IP (VoIP)), data (typically Ethernet or V.35), video, and/or telemetry (TTL, ECL, RS530, etc.). Often, the ONT functions are separated into two parts: the ONU, which terminates the PON and presents a converged interface - such as xDSL or multiservice Ethernet - toward the user, and network termination equipment (NTE), which provides the separate, native service interfaces directly to the user. The OLT sends a single stream of downstream traffic that is seen by all ONTs. Each ONT only reads the content of those packets that are addressed to it. Encryption is used to prevent eavesdropping on downstream traffic.
Installation cost of PON is reduced by allowing an optical transceiver at the network end of the PON based access system to be shared with many users. Such installations minimize the number of trunk/feeder fibers (i.e., fibers leaving the network's optical line termination function). Also, operations cost are reduced by the passive nature of the optical distribution network.
Today the service providers are endorsing next-generation, packet-based integrated voice and data access platforms for fiber-to-the-home (FTTH) networks, but video still presents unique challenges because of its bandwidth and transmission requirements. With the advent of interactive TV (ITV) and switched video-on-demand (SVOD), these challenges exacerbate. The deployment of video services requires a cost-effective solution that can support evolving services with requirements that may not yet be known.
The market for video services is enormous and growing. There are now over 73 million households subscribing to basic cable TV (CATV) services and over 17 million paying for satellite-delivered TV services. For network operators, video represents a highly attractive broadband service offering in terms of revenue potential, both for content and advertising. This potential is increasing as services such as pay-per-view (PPV) and video-on-demand gain subscribers.
Successful deployment of FTTH networks from both a technology and financial standpoint will require the ability to deliver video services effectively along with voice and data services. This "triple-play" of voice, video, and data is a revenue component for the future success of service providers. Today, many networks face bandwidth constraints in the last mile, so delivering all of these services is either impossible or requires that service providers operate parallel networks. To compete successfully, service providers
will need to transform their access networks to deliver all of these services via a single integrated transport and access solution.
The current fiber access systems in the first mile based on Gigabit Ethernet Passive Optical Networks support only 32 or 64 subscribers over single PON. There is a great need for service provider to support more subscribers on single PON because of the demand for VOIP, High-Speed Internet data, Analog video/RF video, Digital Video entertainment and broadband services.

Detailed description of the Drawing
While this specification concludes with claims particularly pointing out and distinctly claiming that, which is regarded as the invention, it is anticipated that the invention can be more readily understood through reading the following detailed description of the invention and study of the included examples.
Systems and methods are disclosed for providing access to a Gigabit Ethernet Passive Optical Network (GEPON). In particular, an access system based on PON is disclosed that has a high density of users (costumers or subscribers). With the advent of digital telephony, IPTV, and popularity of internet, there is a large scope of expanding existing communication networks to accommodate the ever increasing number of subscribers. This is true especially for optical communication networks that are capable of providing high bandwidth access to users while maintaining a high quality of service.
According to an embodiment, the access system includes a service provider equipment or an Optical Line Terminal (OLT) configured to receive access requests from a plurality of users subscribing to a service. The service may include one or more of voice over internet protocol (VOIP), data and video transmission (IPTV, analog video/RF video etc.) through a single mode optical fiber. The access system also includes a subscriber premises equipment or an optical networking Unit (ONU) configured to present a user interface and provide access to the plurality of users through a plurality of associated ports on receipt of the access requests. In addition, the access system includes a network terminal equipment (NTE) or a Network Management System (NMS) configured to manage the service provider equipment and the subscriber premises equipment to provide the service to the users.
By providing more users or subscribers over single Passive Optical Network (PON) on single-mode optical fiber, the revenue will enhance by 24 times and would reduce the cost of system deployment by orders of magnitude.
Fig 1 illustrates an embodiment of an access system 100 based on Gigabit Ethernet Passive Optical network (GEPON), in general, according to the present invention. Accordingly, the access system 100 includes a service provider equipment 102 installed at the central office of the service provider. The service provider equipment 102 is configured to receive access requests from a plurality of users subscribing to a service. The service may correspond to one or more of voice, data, and video transmission at three different wavelengths. In an implementation, the service provider equipment 102 provides an interface between the PON and backbone network. The interfaces may include one or more of Internet Protocol (IP) traffic over Gigabit, 10G, or 100 Mbit/s Ethernet, standard time division multiplexed (TDM) interfaces such as SONET/SDH or PDH at various rates, and ATM UNI at 155-622 Mbit/s. In an embodiment, the service provider equipment 102 is configured for communication of data at three different wavelengths for downstream, upstream, and analog video/RF video transmission. Further, to support more number of users or subscribers, the service provider equipment 102 is configured to dynamically allocate bandwidth to each of the users based upon the terms and conditions of the subscription.
The access system 100 further includes an optical distribution network 104 in optical communication with the service provider equipment 102. The optical distribution network 104 includes passive optical splitters and fibers. The passive optical splitters are passive due to absence of any active electronic component. The optical distribution network 104 splits a single mode optical fiber from the service provider equipment 102 to a plurality of optical fibers. Each of the plurality of optical fibers is connected to a corresponding subscriber premises equipment 106 thereby enabling sharing of bandwidth between plurality of subscriber premises equipments 106. The subscriber premises equipment 106 is configured to present a user interface and provide access to the plurality of users through a plurality of associated ports on receipt of the access requests. The subscriber premises equipment 106 includes a multi-port switch module configured to present a user interface and provide access to a plurality of users through associated input/output ports. The multi-port switch enables availability of a service to a plurality of users using a single subscriber premises equipment 106. As discussed earlier, the optical distribution network 104 connects a single service provider equipment 102 to a plurality of subscriber premises equipment 106 thereby supporting more number of subscribers/users per service provider equipment 102. The access system 100 further includes a router 108, a video server 110 and a voice over internet protocol (VOIP) gateway server 112 in communication with the service provider equipment 102 through a switch 114 as shown in the figure. The communication link between the switch 114 and the service provider equipment 102 may correspond to an optical fiber link.
Further, the service provider equipment 102 connects to a network 116 to communicate with a Network Terminal Equipment (NTE) 118. The network 116 may correspond to a wired or wireless network for the purposes of the ongoing discussion. The Network Terminal Equipment (NTE) 118 is configured to manage the service provider equipment 102 and the subscriber premises equipment 106 to provide a given service to the plurality of users. To this end, the NTE 118 hosts a network management software that allows for remote provisioning and maintenance of the PON network.
Fig 2 shows an implementation of the access system 200 based on GEPON according to the present invention. Accordingly, the access system 200 includes an optical line terminal (OLT) 202 (an embodiment of the service provider equipment 102 of fig 1) configured to provide an interface between the PON and backbone network. The OLT 202 is configured to receive access requests from a plurality of users subscribing to a service. The service may correspond to one or more of voice, data, and video transmission at three different wavelengths.
In an implementation, the OLT 202 is configured for communication of data at three different wavelengths for downstream, upstream, and analog video/RF video transmission. These wavelengths correspond to 1490nm, 1310nm, and 1550nm respectively. Further, to support more number of users or subscribers, the OLT 202 is configured to dynamically allocate bandwidth to each of the users based upon the terms and conditions of the subscription.
The access system 200 further includes an optical distribution network (ODN) 204 in optical communication with the OLT 202. The ODN 204 includes passive optical splitters and fibers. The ODN 204 splits a single mode optical fiber from the service provider equipment 102 into separate strands feeding individual optical network units (ONUs) (an embodiment of subscriber premises equipment) 206-a, 206-b, and 206-c respectively as shown in the figure.
The ODN 204 includes one or more splitters and optical fibers connecting the splitters. In an example embodiment, the ODN includes 1:32 passive optical splitter that is configured to receive a single optical fiber from the OLT 202 and split the optical fiber to 32 separate strands that connect to 32 ONUs 206. In an alternative embodiment, the ODN 204 may include one 1:4 passive optical splitter 204-a and four 1:8 passive optical splitters. Such an arrangement as shown in the figure results in splitting of one optical fiber from the OLT 202 into 32 optical fibers that feed 32 different ONUs 206. The ODN 204 thus enables dynamic sharing of bandwidth (e.g. 1 Gbps) between plurality of subscriber premises equipments (such as, 206-a, 206-b, and 206-c) in first mile access systems such as 200 that implements PON networks up to 20 Kms. Since the ODN 204 is shared, upstream transmissions may collide if they were transmitted at random times. The ONUs 206 can lie at varying distances from the OLT 202 thereby resulting in a unique transmission delay from each ONU 206. The OLT 202 measures such delays and sets a register in each ONU via PLOAM (physical layer operations and maintenance) messages to equalize the delay with respect to all of the other ONUs in the PON. It may be appreciated that the components between dotted lines in fig 2 comprise a lGbps PON that includes the OLT 202, the ODN 204 and the ONU 206.
In an exemplary embodiment, the ONU 206 terminates the PON and presents native service interfaces to the user. Such services includes voice (plain old telephone service (POTS) or voice over IP (VoIP)), data (typically Ethernet or V.35), video, and/or telemetry (TTL, ECL, RS530, etc.). Often, the ONU functions are separated into two parts: the ONU, which terminates the PON and presents a converged interface - such as xDSL or multiservice Ethernet - toward the user, and network terminal equipment (NTE), which provides the separate, native service interfaces directly to the user. The OLT 202 sends a single stream of downstream traffic that is seen by all ONUs 206. Each ONU 206 only reads the content of those packets that are addressed to it. Encryption is used to prevent eavesdropping on downstream traffic.
In an implementation, each ONU 206 has a 24 port switch that has 24 output ports that feeds 24 subscribers or users. The ONU 206 provides access and a user interface to users at each of these ports. In such an implementation, each OLT 202 communicates with 32 such ONUs 206 to provide a service to up to 768 users or subscribers. The Access system 200 supports services, such as, voice, data and video transmission. The various end user equipments and the associated networks have been shown as 208, 210, 212, and 214. To support various services over the lGbps PON, a video server 218, and a VoIP gateway 220 in communication with the OLT 202 through a switch 222 by a 1 Gbps optical link. The OLT 202 further connects to a network 224 to communicate with network terminal equipment 226.
The network terminal equipment (NTE) 226 is configured to manage the OLT 202 and the ONU 206. To this end, the NTE 226 hosts an operating system OS 228 to remotely monitor the PON. It may be appreciated by those skilled in the art that the OS 228 supports the increased number of users or subscribers (i.e. 768 users with 1 OLT and 32 ONUs). In an alternative implementation, the OS 228 enables the NTE 226 to perform authentication and authorize the plurality of users based on access requests received from the plurality of users. The NTE 226 may also be configured by the OS 228 to provide a given service based on a predetermined quality of service (QoS).
The access system 200 further includes an analog video/RF video source 230 that feeds analog video/RF video to the OLT 202. In an exemplary implementation, the OLT includes a Wavelength Division Multiplexing module 232 that enables the OLT 202 to utilize three wavelengths downstream, upstream and analog video/RF video transmission. The wavelengths for Ihe downstream, upstream, and analog video/RF video transmission correspond to 1490nm, 1310nm, and 1550nm respectively. A passive optical network (PON) according to the present invention greatly simplifies network operation, maintenance and cost since it uses much less fiber than in point-to- point fiber topologies. The Gigabit Ethernet PONs (GEPONs) -support a point to multi¬point fiber topology. The OLT 202 supports speeds of lGbps to communicate with the ONUs (206) over the passive optical network (108) up to a distance of 20km on single- mode fiber. Also, the OS 228 in an NTE 226 is a complete network management system allowing remote provisioning and maintenance of PON. Access management system eliminates the high-costs associated with truck rolls and outside plant maintenance. With a web-based GUI, OS 228 in the NTE 226 is flexible and easy to access. The user interface is provided through a web browser for the NTE's GUI or through a console. In an implementation, the access system 200 can support up to 768 subscribers. In such an implementation, the PON includes one OLT 202 and up to 32 ONUs 206. Each ONU 206 can support up to 24 subscribers with data rates of 10/100Mbps. Each subscriber bandwidth can be provisioned dynamically in increments of 64kbps. The ONUs 206 support optional configurations like Analog video/RF video and different port configurations. A symmetrical bandwidth of lGbps is shared dynamically among 768 subscribers over a distance of 20kms on optical fiber.
Fig 3 shows an embodiment of service provider equipment (SPE) 302 (or OLT 202) according to the present invention. Accordingly, the SPE 302 includes an EPON scheduler/sharper module 304, an Ethernet Passive Optical Network (EPON) lookup engine 306, Dynamic Bandwidth Allocation (DBA) control 308, a burst transceiver module 310, a Wavelength Division Multiplexing (WDM) module 312, and other modules 314.
Some services - POTS, for example - require essentially constant upstream bandwidth, and the OLT2Q2 or SPE 302 (or 102) may provide a fixed bandwidth allocation to each such service that has been provisioned. But much data traffic - internet surfing, for example - is bursty and highly variable. Using the DBA control module 308, a PON can be oversubscribed for upstream traffic, according to the traffic engineering concepts of statistical multiplexing. Downstream traffic can also be oversubscribed, in the same way that any LAN can be oversubscribed. '
The WDNM module 312 Wavelength Division Multiplexing (WDM) module enables the SPE 302 to communicate data at three different wavelengths for downstream, upstream, and analog video/RF video transmission respectively. The three different wavelengths correspond to 1490nm for downstream transmission, 1310nm for upstream transmission, and 1550nm for analog video/RF video transmission.
Burst transceiver module 310 enables the SPE 302 to transmit and receive bursts of information/data. Other modules may include modules like Ethernet MAC, Gigabit SreDes, EPON SerDes, etc.
Fig. 4 shows an embodiment of subscriber premises equipment 402 according to the present invention. The SPE 402 (or 106 or ONU 206) includes an optical burst transceiver 404, an RF video output module 406 and a 24 port switch module 408, and other modules 410.
Fig. 5 is a flow diagram illustrating an example method for providing access to a plurality of users in a GEPON (Gigabit Ethernet Passive Optical Network). At block 502, access requests are received from a plurality of users subscribing to a service. In particular, the access requests are received by a service provider equipment (102). The access requests correspond to the type of service requested by the plurality of users. In an implementation, the service includes communication of one or more of voice, data and video through a single mode optical fiber. In an example implementation, the access request can be made by at least 768 subscribers through at least 32 subscriber premises equipments.
Further, in an implementation, communication of data at three different wavelengths for downstream, upstream, and analog video/RF video transmission can be provided. In particular, in an implementation, a Wavelength Division Multiplexing (WDM) (312) residing in the service provider equipment (102) can provide communication of data at three wavelengths. In this implementation, the three different wavelengths correspond to 1490nm for downstream transmission, 1310nm for upstream transmission, and 1550nm for analog video/RF video transmission. In an alternative embodiment, the Wavelength Division Multiplexing (WDM) (312) may be implemented outside the service provider equipment (102).
At block 504, access to the service is provided to the plurality of users. In particular, in an example embodiment, the access is provided by a subscriber premises equipment (106) to the plurality of users. In this embodiment, the access to service is provided to a plurality of users through a plurality of input/output ports configured in the subscriber premises equipment (106). It is to be appreciated that each one of the input/ output ports correspond to each one of the plurality of users. In an example embodiment, each of the subscriber premises equipment (106) includes a 24-point switch module (408). Accordingly, the 24-point switch module is configured to present a user interface and provide access to 24 users through 24 associated input/output ports. In an implementation, upon receipt of an access request bandwidth is allocated dynamically, to the plurality of users. In this implementation, the dynamic allocation is performed by a dynamic bandwidth allocation module (308) residing in the service provider equipment (102). In an example implementation, dynamic allocation is performed based on a predetermined priority condition of the service. The pre-determined priority condition may correspond to assigning highest priority to video and voice communication and assigning lowest priority to data communication (access request sent by a plurality of users). In a further implementation, the plurality of ports may be provisioned in increments of 64 kbps starting from a bandwidth of 256 kbps to 100 Mbps. Further, in this embodiment, the subscriber premises equipment (106) and the service provider equipment (102) are in optical communication with each other through an optical distribution network (118). In this embodiment, the optical distribution network splits an optical fiber connected to the service provider equipment (102) to a plurality of optical fibers connected to the subscriber premises equipment (106). Thus data (corresponding to the subscribed service) is transmitted through the optical fiber connected to the service provider equipment (102) to the plurality of optical fibers connected to each of the corresponding subscriber premises equipment (106). It is to be appreciated that each of the plurality of optical fibers are connected to the corresponding subscriber premises equipment (106). In an example embodiment, data is transmitted to 32 subscriber premises equipment (106).
Furthermore, in an implementation, access to service may be provided to the plurality of users in the last mile by wireless connectivity including any of Wifi and WiMAX. In an alternative implementation, access to service may be provided to the plurality of users by employing wire line connectivity.
At block 506, the service provider equipment (102) and the subscriber premises equipment (106) are managed for providing service to the plurality of users. In an implementation, managing includes performing authenticating and authorizing the plurality of users based on access request received from the plurality of users. In a further implementation, managing includes providing service based on a predetermined Quality of Service (QOS) requirement associated with the service. In this implementation, the QOS may be based on a service level agreement made at the time of subscription by the users.
In an implementation, the NTE 226 supporting OS 228 is used for providing a management interface to the PON Optical Access system 100 (or 200). The OS 228 supports the management of multiple GEPON systems since it connects to multiple OLTs 202 (or Service provider equipment 102) through an IP network 224 (or 116). A customer interface is provided through a web browser for the Network terminal equipment 118 (226) - GUI. The GUI supports remote connection and can be launched locally on the NTE 118. The NTE 118 provides multiple sessions for the GUI to perform: network management from any location, web based management, management of multiple PONs, end-to-end provisioning, configuring user SLA with PON capacity knowledge, remote management with advanced OAM&P functions, remote software upgrade, advanced alarm filtering and browsing, performance management providing current data statistics, pre-provisioning support, etc.
The disclosed systems and methods increase the density of subscribers or users by 24 times as compared to the existing systems and methods. Also, the disclosed access systems are very cost effective for the service provider because the access system offers more density on single PON and enhance revenue of the service provider. Also, PONs cost less per household for two reasons: there is less fiber in the network, because the fiber is shared down to the final passive optical splitter; and the signal is delivered passively as light, without conversion in the network into electrical signals, which saves on both equipment and network maintenance i.e., Operating Expense (OPEX). In particular, there is no need to maintain active electronic devices in the field since the whole network is passive.
The Gigabit Ethernet Passive Optical Network (GEPON) disclosed herein enables a service provider to offer business customers (users or subscribers) with on demand provisionable bandwidth up to 100Mbps for services over an optical fiber. The services include high bandwidth data services, dedicated VLAN, Voice over IP (VoIP), video conferencing, Video on Demand (VoD), etc. The service provider may also offer the subscribers with on demand provisionable bandwidth up to 10Mbps for services over optical fiber with optional wireless (WiFi) LAN access.
