Overview:
This product is designed for the connection between the Optical fiber cable and the main points, and it is a kind of port device. It has the function of direct or indirect connection, coiling, storage, and dispatching on the fiber cable.
Cabinets are made of double side wiredrawing stainless steel; with the protection grade reaching IP65.thermosetting fiberglass-reinforced polyester can endure climate changes and adverse environment. All front access. Modular design; Flexible configuration and quick installation; Suitable for ribbon and no ribbon optic fibers;
30 °oblique installation of adapters, preventing eyes from laser’s hurts and ensuring the fiber bending radius; Suitable for inserting installation of SC, FC, ST (additional flange) adapters; the bending radii are ensured to be more than 40mm in anyplace. Reliable fiber introduction, grounding and fixing; Swpa convenient; Suitable fiber integrated and optical fibers; A special suspension mechanism is designed to enable ground mounted, wall-mounted or aerial for users’ requirement.

The requirements of the function:
- The fiber fixation and protection function
Fiber inlet, fixation and protection device should be provided. The fibers will be protected from being damaged when they are let in and fixed in the frame through these devices. The metal parts of the cables are insulated from the machine. The metal jacket of the cable & the reinforced core should be connected with the high voltage protective earthing device after being fixed;
2. The termination & connection function
Termination device should be provided, which is used for the connection operation, construction, installation & maintenance. It could fix and protect the connector and make sure the connector even but not displaced and free from external influence, guarantee the coiled fibers and pigtails not damaged;
