The telecommunication optical cables cross connection cabinet works as an interface equipment at the node of the trunk optic cable of Optic fiber access network and distribution optical cables, providing the functions of splicing termination, storage and dispatching for optic fibers.

This series of products can be installed with CLG01 outdoor communication equipment access control management system. Nanjing putian is the first enterprise which researched and developed the telecommunication optic cross connection cabinets, and was commissioned by the ministry of national information industry in 1998, drafted and composed the communication trade standard YD/T988-1998 the telecommunication cross connection cabinet of the products.

Features
1. The shell of the equipment adopts SMC mode pressing reinforces composite material and imported stainless steel cabinet, and is the patent product of Nanjing putian( the paten application number: 97017101.5). The features are as follows:
The door hinge of the shell is of integrated structure with high intensity.
The door lock adopts a triplex guard-tooth core to ensure an effective guard against theft. And the lock is of valve structure, preventing the entering of foreign materials into the lock core. The heat-barrier material is fit inside to avoid dew.

2. The optic fiber movable connectors inside the equipment adopt obliquity adapters and the following features:
The operation of jumper connector of termination module is convenient and safe. The bending radius is large, reducing the signal loss of the fiber in storage to the maximum.
The adapter of the termination module is removable and easy to replace. The panel can be uncovered to make a more convenient operation of pigtails.
