The present disclosure relates to optic fibre cable telecommunication systems, and more specifically relates to optical fibre cable clamping apparatus used in the optic fibre cable telecommunication systems.
BACKGROUND
[0002] A distributed fibre network typically includes large network of installed optical fibre cables connected to multiple electronic and mechanical devices. The optical fibre cables initiate from multiple terminals and are periodically opened and spliced for allowing data to be distributed to other cables in branches of the distributed fibre network. The optical fibre cables' branches may be further distributed until the distributed fibre network reaches individual homes, businesses, offices, premises, and the like with use of telecommunications closures/enclosure such as splice (en)closures. The opened regions in the optical fibre cables are protected by the splice closures to protect exposed fibres and interiors of the optical fibre cables. The splice closures have multiple input and output ports for entry and exit of the optical fibre cables. Traditionally, the splice closures are designed to facilitate management and protection of individual spliced fibres.
[0003] Further, the optical fibre cables in the distributed fibre network may be installed on different support structures like walls, poles and underground structures and environments. Traditionally, different telecommunications closures with application specific designs are required for each support structure. The different closure designs are required for different mounting orientations like horizontal and vertical orientations. Additional splitter enclosures are required for signal distribution into multiple fibres. Moreover, the use of different closures with different strength and performance for different installation environment arise a challenge in griping, clamping and securing a fibre reinforced plastic (FRP) central loose tube cable within a very less space inside 8 Port/12 Port and 4 Port terminals. Also, safely guiding the FRP loose tube cable to receptacles of the

aforesaid terminals is a big challenge in the present scenario. Some of the prior art references are given below:
[0004] For example, a prior art reference "US6487344B1" discloses a watertight inlet device for inserting a cable containing optical fibers into a chamber or into a container via an inlet passageway provided for this purpose: said device being fitted to the cable and secured to the strength members thereof before the cable is inserted into the chamber or container, the outer sheath of the cable further being secured directly on the watertight inlet device, the watertight inlet device then being received by being threaded into the chamber or container, and being locked therein by keying.
[0005] Similarly, a prior art reference "US6269214B1" discloses an optical fiber organizer and a box for receiving it. The inlets for the optical cables project side-by-side in row abreast from the same short side of the box bottom. The organizer includes a pedestal which receives, in nested manner, stackable modules for holding cassettes. The pedestal is made of a plastics material and has an outside shape that is rounded. A transit empty space is provided before the pedestal for the purpose of passing the fibers, and a storage empty space is provided after the pedestal for the purpose of storing standby fibers.
[0006] Furthermore, a prior art reference "US8879883B2" discloses an optical fiber cable inlet device and telecommunications enclosure system, where an inlet device is described for inserting a cable containing optical fibers into a telecommunications enclosure. The inlet device includes a housing with a strength member securing section configured to fasten at least one strength member to the housing. The inlet device further includes a fiber guide device. The inlet device may be used in a single fiber optical cable assembly or multi-fiber optical cable assembly.
[0007] While the prior arts cover various approaches to overcome the above stated drawbacks, there are no significant considerations to counter drawbacks associated with challenges in griping, clamping and securing the FRP central loose tube cable within the very less space inside the 8 Port/12 Port and 4

Port terminals. In light of the above-stated discussion, there is a need to overcome the above stated disadvantages.
[0008] Any references to methods, apparatus or documents of the prior art are not to be taken as constituting any evidence or admission that they formed, or form part of the common general knowledge.

[0027] Each of the lower clamp member 102 and the upper clamp member 106 may have the grooved fibre extension 110 to provide passage to the one or

more optical fibre elements 108. Similarly, each of the lower clamp member 102 and the upper clamp member 106 may have the two grooved strength member extensions 206 to provide passage to the two strength members 204. Alternatively, the optical fibre cable clamping apparatus 100 may have more than two grooved strength member extensions. The grooved fibre extension may be formed between the operably coupled the upper clamp member 106 and the lower clamp member 102 to provide passage to the one or more optical fibre elements 108. That is, the grooved fibre extension 110 may be formed in the operably coupled the upper clamp member 106 and the lower clamp member 102, wherein the one or more optical fibre elements 108 may be placed in the grooved fibre extension 110. Similarly, the two grooved strength member extensions 206 may be formed between the operably coupled upper clamp member 106 and lower clamp member 102 to provide passage to the two strength members 204.

The at least two anchor hooks may be provided either on the upper clamp member 106 or the lower clamp member 102. The optical fibre cable clamping apparatus 100 may, in an additional space of a terminal 302, clamp the two strength members 204 and the one or more optical fibre elements 108 that enter into the terminal 302. In general, the terminal is referred as a point at which a conductor from a component, device or network comes to an end. The

terminal 302 may also refer to an electrical connector at this endpoint, acting as the reusable interface to a conductor and creating a point where external circuits can be connected. The terminal 302 may simply be the end of a wire or it may be fitted with a connector or fastener.
[0032] FIG. 2 illustrates the exemplary arrangement 200 over the lower clamp member 102 of the optical fibre cable clamping apparatus 100. The exemplary arrangement 200 may include the least two circular crimp sleeves 202, the two strength members 204, the lower clamp member 102, the at least one elongated member 104, and the one or more optical fibre elements 108. The optical fibre cable clamping apparatus 100 has the two strength members 204 that may split apart forming the Y profile into the optical fibre cable clamping apparatus 100. The Y profile may be formed on each of the upper clamp member 106 and the lower clamp member 102 due to the two grooved strength member extensions.
