Description:FIELD OF THE INVENTION
[1] The present disclosure pertains to the field of terminal boxes for fibers. Specifically, the present disclosure pertains to a fiber terminal box that is compact, mistakeproofingly installs, distributes and maintains fibers, providesefficient transmission of optical signals offering stable performance.

BACKGROUND OF THE INVENTION
[2] A typical fiber terminal box receives fiber/optical fibers from a transmission line and are routed-in the terminal box and supported within the terminal boxand distributed to a plurality of utilities, for example to different houses of a residential society.Each known fiber terminal box has a single compartment. The single compartment houses the arrangement of fibers received from the transmission line and the arrangement of fibers for distribution to various utilities and the fibers are accessed by unlocking the compartment. As a known work execution, there are two teams that access the single compartment, namely an installation team and a distribution team. The installation team installs fibers received from the transmission line to the fiber terminal box and maintains the fibers and the distribution team distributes fibers to various utilities and maintains the fibers. As a single compartment contains installation fibers and distribution fibers, occurrences of mistakes are likely, for example the distribution team mistakenly works/tampers on fibers received for installation and vice-versa. Further, as there is single lock for a known fiber terminal box, management of key is difficult due to unavailability of key. Further, fibers are not routed in desired manner and hence optical transmission efficiency can be hampered and unstable performance can be experienced. Undesired routing of fibers results formation of cracks thereby reducing life of fibers and requiring frequent maintenance and replacements adding to cost. Also, as fibers are positioned in one compartment, there is no space availability forsleeve splicing and splitters.

[3] EP2674800 and US10514520 disclose asingle compartment terminal box. Figure 1 discloses an exemplary internal view of a known fiber terminal box (01) with a single compartment. None of the routes of fibers (02) arrange fibers in figure of 8 or in 8-shape rather is cylindrical and hence could lead to unstable performances. The known fiber terminal box (01) includes a base (01a) and a cover (01b). The base (01a) receives installation fibers (02) which are routed to cover (01b)and distributed from a drop cable out (01c). The routing space occupied by fibers (02) is more.

[4] Hence, there is a need for afiber terminal box that alleviates some of the above mentioned drawbacks.

OBJECTS OF THE INVENTION
[5] Some of the objects of the arrangement of the present disclosure are aimed to ameliorate one or more problems of the prior art or to at least provide a useful alternative and are listed herein below.

A principle object of the present disclosure is to provide a fiber terminal box that has separately accessible mistake-proofing compartments by an installation team and a distribution team with 8 shaped fibers routing with sleeve splicing to provide stable performance.

Another object of the present disclosure is to provide afiber terminal box that has fibers routed in 8-shaped that results in achieving compactness and efficient transmission of optical signals offering stable performance.

Still another object of the present disclosure is to provide a fiber terminal box that has two compartments that provides separate access of installation fibers to an installation team and distribution fibers to a distribution team and hence eliminates routing and maintenance mistakes and eliminates dependency for unlocking.

Yet another object of the present disclosure is to provide a fiber terminal box that has sufficient space to accommodate sleeve splicing and splitters which conventionally lacks.
