Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber wiring for communication, in particular to an optical fiber wiring frame for communication. Background Art

[0002] Optical fiber is the abbreviation of optical fiber, which is a fiber made of glass or plastic and can be used as a light transmission tool. The transmission principle is "total reflection of light". The optical fiber communication system uses light as the carrier and uses extremely pure glass to draw extremely fine optical fibers as the transmission medium. Through photoelectric conversion, the communication system uses light to transmit information. The communication using optical fibers is called optical fiber communication. In the process of optical fiber connection construction, a special distribution frame is required to assist. The optical fiber distribution frame is a wiring connection device between optical cables and optical communication equipment or between optical communication equipment.

[0003] The existing fiber optic distribution frame has structures of closed, semi-closed and open types. The optical fiber is passed through the rack routing limiter in the rack, the fiber optic coupler is plugged into the rack, and then the optical fiber is connected to the fiber optic coupler to realize the optical fiber wiring for communication.

[0004] The existing optical fiber distribution frames for communication have the following problems: the optical fiber routing in the frame is limited by a single wire clamp, and the wire clamp is unchanging. When the thickness of the wire bundle and the number of routing loops are different, the limiting effect of the wire clamp on the optical fiber is different, and it can only be adapted to optical fiber couplers of specified sizes. For this reason, we propose an optical fiber distribution frame for communication. Utility Model Content

[0019] 2. Wind the pigtail around the cable management reel. When winding the cable, push the paddle upwards. After placing the optical fiber into the lower end of the limit block, release the paddle. The paddle is subjected to the torsion of the torsion spring and automatically rebounds to the initial position, thereby fixing the pigtail. Regularly wind the fixed optical cable of the optical fiber coupler away from the outside into the upper cable management rack. As above, fix the fixed optical cable through the optical fiber line limiting mechanism. The cable routing is not affected by the thickness of the wire bundle and the number of wiring loops, and the fixing effect is the same.
