What functions should the optical fiber terminal box have as the terminal equipment of the optical cable line?

2022-03-17

Fiber optic boxes, also known as fiber optic distribution frames, are used to transmit digital and similar voice, video and data signals using fiber optic technology. The optical fiber box is also called the optical fiber terminal box, which is the optical terminal connection box, which is used for the overhead, pipeline, underground, and straight-through and branch connections of the optical cable.


Connecting function: After the optical fiber drawn from the optical cable is spliced with the pigtail cable, the redundant optical fiber is coiled and stored, and the fusion splice is protected.


Fixing function: After the optical cable enters the rack, the outer sheath and reinforcing core shall be mechanically fixed, the ground wire protection components shall be installed, the end protection shall be performed, and the optical fibers shall be grouped and protected.


Adjustment function: plug the connector attached on the pigtail cable to the adapter, and realize the optical path docking with the optical connector on the other side of the adapter. Adapters and connectors should be able to be plugged and unplugged flexibly; optical paths can be freely deployed and tested.


Storage function: Provide storage for various cross-connected optical cables between racks, enabling them to be placed regularly and neatly. The fiber optic terminal box should have appropriate space and method, so that this part of the optical connection line can be clearly routed, easy to adjust, and can meet the requirements of the minimum bending radius. 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.
