Optical fiber distribution frame open-type
The fiber distribution frame is important in the optical access network, similar to the existing cable distribution frame. It mainly adopts the traditional MDF type cable management mode, that is, the in-line module part is the outer line side, providing outdoor optical cable fixing, confluence, and splicing. With the terminal function, the horizontal module part is the inner line side, providing the terminal, scheduling, measurement and management functions of the indoor fiber optic cable.

Performance characteristics:
·Line side cable and equipment side pigtail cable partition management, in line with modern maintenance habits;
·The front side is the line side and the back side is the equipment side;
·Both the in-rack and inter-rack jumpers are routed in the rack, eliminating the need to enter the fiber channel of the equipment room, reducing the channel pressure and facilitating dispatch management;
·The cable, pigtail, and fiber jumper are independent of each other and do not interfere with each other;
·Jump fiber length can be customized, reducing fiber redundancy and winding;
·The pigtail cable can be spliced into the frame, no need to customize the length of the pigtail cable, and the pigtail cable can be laid.
