Optical fiber terminal box is also called optical fiber distribution frame, which is used to transmit digital and similar voice, video and data signals using optical fiber technology. The optical fiber box is also called the optical fiber terminal box, which is the optical termination box, which is used for the overhead, pipeline, underground, and direct connection and branch connection of the manhole.
Containment function: After the optical fiber drawn from the optical cable is fused with the pigtail cable, the excess optical fiber is coiled and stored, and the fusion splice is protected.
Fixing 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 fiber shall be grouped and protected.
Allocation function: plug the connector attached to the pigtail 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 flexibly plugged and unplugged; the optical path can be freely deployed and tested.
Storage function: Provide storage for various cross-connected optical cables between racks, so that they can be placed in a regular and orderly manner. There should be an appropriate space and method in the optical fiber terminal box to make the wiring of this part of the optical connection line clear, easy to adjust, and to 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.
