What is an optical fiber distribution box

Optical fiber distribution box, ODB for short. It is suitable for the wiring connection of optical cable and optical communication equipment. Through the adapter in the wiring 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 optical fiber terminal points in the optical fiber access network. Regarding its mechanical properties:
Connector plug-in durability life>1000 times.
The entire curvature radius is controlled to ensure that the curvature radius of the fiber at any position is greater than 30mm.
Each optical fiber is clearly marked, so as to avoid possible confusion caused by disassembly during maintenance.
Flame retardant: Meet the requirements of GB5169.7 Test A.
Regarding its electrical properties:
Connector attenuation (insertion, interchange, repetition) ≤ 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 arcing.
Grounding wire cross-sectional area: >6mm2, there is an obvious grounding mark at the grounding place.
