Optical fiber distribution box (ODB) is suitable for the connection of optical cable and optical communication equipment. Through the adapter in the distribution box, the optical signal is led out by the optical jumper to realize the optical wiring function. It is suitable for the protective connection of optical cables and distribution pigtails, as well as the use of fiber termination points in fiber access networks.
Mechanical behavior
Connector insertion and removal durability life> 1000 times.
Full radius of curvature control to ensure that the radius of curvature of the fiber is greater than 30mm at any location.
Make clear identification of each optical fiber, so as to avoid the confusion caused by disassembly during maintenance.
Flame retardant: meets the requirements of GB5169.7 Experiment A.
Electrical performance
Connector attenuation (insertion, interchange, repeat) ≤0.3dB;
Return loss: APC type ≥60dB, UPC type ≥50dB, PC type ≥40dB;
High-voltage protective grounding device:
Insulation resistance: ≥1000MΩ / 500V (DC).
Withstand voltage: ≥3000V (DC) / 1min, no breakdown, no flashover.
Ground wire cross-sectional area:> 6mm2, there is a clear ground mark at the ground.

Various connectors are easy to terminate and flexible to install.
There are various specifications such as drawer type and fixed type;
Modular fiber distribution box termination is more convenient and more flexible to use;
