As the terminal equipment of the optical cable line, the optical fiber terminal box should have 4 basic functions.
①Fixed function After the optical cable enters the rack, its outer sheath and reinforcing core shall be mechanically fixed, ground wire protection parts shall be installed, end protection treatment shall be carried out, and the optical fibers shall be grouped and protected.
② Splicing function After the optical fiber drawn from the optical cable is spliced with the tail cable, the excess optical fiber is coiled and stored, and the spliced joint is protected.
③Adjustment function Plug the connector attached to the tail cable to the adapter, and realize the optical connection with the optical connector on the other side of the adapter. Adapters and connectors should be able to be inserted and removed flexibly; the optical path can be freely deployed and tested.
④Storage function Provides storage for various cross-connected optical cables between racks, enabling them to be placed in a regular and orderly manner. There should be a proper space and method in the fiber terminal box to make the wiring of this part of the optical connection line clear, easy to adjust, and meet the minimum bending radius requirements. With the development of optical fiber networks, the existing functions of optical fiber terminal boxes can no longer meet many new requirements. Some manufacturers add some optical fiber network components such as optical splitters, wavelength division multiplexers and optical switches directly to the optical fiber terminal box.
