, Description:OPTICAL FIBER CABLE FOR ACCESS NETWORK

TECHNICAL FIELD
[0001] The present disclosure relates to the field of optical fiber cable. More particularly, the present disclosure relates to an optical fiber cable for use in a fiber optic access network.

BACKGROUND
[0002] A vast number of fiber optic networks have been deployed over the last few years. These fiber optic networks are used for various applications including internet services, communication applications and the like. The fiber optic networks are set up using optical fiber cables. These optical fiber cables include buffer tubes. These buffer tubes enclose optical fibers. Typically, the number of the optical fibers in each buffer tube is fixed. In general, the buffer tubes are stranded and surrounded by tapes, binding heads and a sheathing layer. Further, the optical fibers from a particular buffer tube are terminated at a specific termination point in the fiber optic network design. The fiber optic network design may include various termination points where the optical fibers are terminated. Also, based on requirement, different termination points require different number of optical fibers to be terminated.

[0003] Several optical fiber cables are available in the prior art which are used for installation in ducts. In US patent number 8525031B2, an optical fiber cable is provided for installation in underground ducts. The optical fiber cable includes a plurality of buffer tubes. Each of the plurality of buffer tubes encloses a plurality of optical fibers. The plurality of buffer tubes surrounds a flexible reinforcement member. The flexible reinforcement member has a water blocking coating. In addition, the plurality of buffer tubes is surrounded by a layer of water blocking tape. Further, the layer of water blocking tape is surrounded by an outer sheath layer made of high density polyethylene. Furthermore, the outer sheath layer includes a plurality of rigid rod strength members placed longitudinally along a length of the outer sheath of the optical fiber cable. The conventional structures of the optical fiber cables have certain limitations. The presently available optical fiber cables have fixed number of optical fibers inside the buffer tubes. The installers drop a required number of optical fibers to be terminated from a particular buffer tube and protect the remaining number of optical fibers inside the fiber enclosure unit. The remaining number of optical fibers needs to be handled carefully in order to prevent the fibers from breaking. Typically, the handling of the optical fibers takes a lot of time and is risky. The presence of the central strength member in the conventional optical fiber cable restricts the horizontal movement of the buffer tubes due to coupling with the central strength member. This makes the mid span access to the buffer tubes using the window cut quite difficult.

[0004] In light of the foregoing discussion, there exists a need for an optical fiber cable which overcomes the above cited drawbacks of conventionally known optical fiber cables.

OBJECT OF THE DISCLOSURE
[0005] A primary object of the disclosure is to provide an optical fiber cable with different combination of number of buffer tubes with different number of fibers per buffer tube.

[0006] Another object of the present disclosure is to provide ease in distribution and termination of the optical fibers as per the design of the optical fiber network.

[0007] Yet another object of the present disclosure is to eliminate storing of the optical fibers for avoiding breaking of the optical fibers.

[0008] Yet another object of the present disclosure is to maintain a circular geometry of the optical fiber cable with different dimensions of buffer tubes.

[0095] In an embodiment of the present disclosure, the outer diameter of the optical fiber cable 100 having three buffer tubes with 2 fibers each and one buffer tube with 12 fibers is in a range of 7.0 millimeters and 7.5 millimeters.

[0096] It may be noted that in FIG. 1A and FIG. 1B, the optical fiber cable 100 has one buffer tube with 12 optical fibers and three buffer tubes with 4 optical fibers; however, the optical fiber cable 100 can include various other combination of buffer tubes and fiber counts in each buffer tube.

[0097] FIG. 2A illustrates a utilization model 200 for the optical fiber cable 100, in accordance with an embodiment of the present disclosure. The utilization model 200 represents utilization of the optical fiber cable 100 with 24 optical fibers. In addition, the utilization model 200 represents an exemplary use of each of the optical fibers in the optical fiber cable 100. In an embodiment of the present disclosure, a first buffer tube with 4 optical fibers can be terminated at point 1 and a second buffer tube with 4 optical fibers can be terminated at point 2. In an embodiment of the present disclosure, a third buffer tube with 4 optical fibers can be terminated at point 3 and a fourth buffer tube with 12 optical fibers can be terminated at point 4.

[0098] FIG. 2B illustrates another utilization model 202 for the optical fiber cable 100, in accordance with another embodiment of the present disclosure. The utilization model 202 represents utilization of the optical fiber cable 100 with 22 optical fibers. The utilization model 202 enables easy distribution of the optical fibers at drop points where different number of fiber dropping is required along the route of the optical fiber cable 100. In addition, the utilization model 202 represents an exemplary use of each of the optical fibers in the optical fiber cable 100. In an embodiment of the present disclosure, 6 optical fibers in a first buffer tube can be terminated at point 1, 4 optical fibers in a second buffer tube can be terminated at point 2 and 12 optical fibers in a third buffer tube can be terminated at point 3.

[0099] In an embodiment of the present disclosure, there is no need of long window cutting at a mid span of 1.5 meter to find the reversal position. In an embodiment of the present disclosure, a maximum of 1 meter mid span is sufficient for dropping the plurality of optical fibers from the optical fiber cable 100. The optical fiber cable 100 does not include a central strength member. In addition, the presence of the central strength member results in an increase in friction which does not enable a skilled person to pull the plurality of buffer tubes using the window cuts. The absence of the central strength member enables the plurality of buffer tubes to be pulled out using window cuts.

[00100] The present disclosure provides numerous advantages over the prior art. The optical fiber cable includes different combination of number of buffer tubes with different number of fibers per buffer tube. This allows an optical fiber cable with a specific combination of buffer tubes and optical fibers to be used for a particular fiber optic network. Also, the different combination of number of buffer tubes and optical fibers eliminates the need for storing excess number of optical fibers from a buffer tube which are not in use in the fiber enclosure at a particular drop point. In addition, the present disclosure provides an ease in distribution and termination of the optical fibers as per the design of the optical fiber network. Moreover, the ease in distribution eliminates messiness to the installers. Further, the circular geometry of the optical fiber cable is maintained with different dimensions of buffer tubes. The exclusion of a central strength member enables easy mid span access using window cut due to absence of SZ stranding of the buffer tubes around the central strength member.
