The four-core fiber access terminal is used to splice fusion, split, and cable optical transmission terminals to transmit data. Fiber access terminal boxes can efficiently terminate and protect the optic cables.

It is an essential piece of equipment needed to transmit data across networks. The four primary fat fiber access terminals comprise four fibers to the branches of the home.

It can be used for wiring cable fiber optics to optical communications equipment. Through the adapters inside the junction box, the optical signal is carried out via a fiber optic patch cable to perform the purpose of optical wiring.

A fiber access terminal (fat) ensures the safe connecting of optical fiber cables and pigtails. It also works for fiber optic termination points in fiber optic-optic access networks.

It can be used in various scenarios, including indoor, multi-level riser, and wall-mounted. It can also be used for replacing old and new wiring boxes and fiber in the house.
