What You Need to Know About Optical Fiber Distribution Box
The optical fiber distribution box is suitable for the wiring connection of optical cable and optical communication equipment. Through the adapter in the distribution box, the optical signal is drawn out by the optical jumper to achieve the optical wiring function. It is suitable for the protective connection of optical cables and distribution pigtails, as well as the optical fiber termination points in optical fiber access networks. Its connector plug and unplug durability life is more than 1000 times. The full curvature radius control ensures that the curvature radius of the fiber in any position is bigger than 30mm. Each fiber is clearly marked to avoid confusion that may be caused by the disassembly during maintenance.
Optical fiber distribution box 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
cross-sectional area of grounding wire: >6mm2, with a clear grounding mark at the grounding point.
Fiber optic distribution boxes are convenient for termination of various connectors and flexible installation. There are various specifications such as drawer type and fixed type. The termination of modular optical fiber distribution box is more convenient and is more flexible to use. It supports the management of various optical fiber connectors, such as SC, LC, ST, MT-RJ, etc. The space of 1U can be terminated with up to 48-core LC or MT-RJ (24 dual-port LC or 24 MT-RJ) optical fiber connectors. It is closed managed, with front operation, quick and easy to install. The height of 1U has two sets of built-in optical fiber coiled rings, and has recessed hidden or flush inlay installation.
The optical fiber distribution box has a wide range of functions, including the introduction, fixing and stripping protection of optical cables, the fusion and protection of optical fibers, the storage of pigtails, the storage and management of jumpers, the fixed connection and cross-connection of optical fibers, etc. At the same time, it can install optical splitters, wavelength division multiplexers and other value-added module units according to customers’ requirements. It can also be used for the termination, use and management of optical cables between wiring and equipment.
