Introduction to the Function and Specifications of the Optical Fiber Distribution Box

The optical fiber distribution box is suitable for the wiring connection between the optical cable and the optical communication equipment. Through the adapter in the distribution box, the optical signal is drawn out with the optical jumper to realize the function of optical wiring. It is suitable for the protective connection of optical cables and distribution pigtails and is also suitable for the use of optical fiber termination points in optical fiber access networks.

1. What is the optical fiber distribution box

The optical distribution box is designed and produced according to the communication industry-standard YD/T 778, which can complete the introduction, fixation and stripping protection of optical cables, fusion and protection of optical fibers, storage of pigtails, storage and management of jumpers, a fixed connection of optical fibers and cross-connection and other functions. At the same time, value-added module units such as optical splitters and wavelength division multiplexers can be installed according to customer requirements. The plug and unplug durability life of its connector is> 1000 times. The full curvature radius control ensures that the curvature radius of the optical fiber is greater than 30mm at any position. Each fiber is clearly marked to avoid confusion that may be caused by disassembly during maintenance.

2. The type of optical fiber distribution box

The connector attenuation of optical fiber cable distribution box (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.

The cross-sectional area of the grounding wire is more than 6mm², and there is an obvious grounding mark at the grounding point.

It is convenient to connect the various connectors of the optical fiber distribution box and it is flexible to install the box. There are various specifications such as drawer type and fixed type. It is more convenient to connect the modular optical fiber distribution box and the use is more flexible. And it supports the management of various optical fiber connectors, such as SC, LC, ST, MT-RJ, etc. In the space of 1U, up to 48-core LC or MT-RJ (24 dual-port LC or 24 MT-RJ) optical fiber connectors can be connected. It is airtight management. It is operated from the front and the installation is quick and easy. It is 1U high and has two built-in optical fiber coiling rings, which can be recessed or flush-mounted.

3. The role of the outdoor optical fiber distribution box

It is used for the wiring connection between optical cable and optical communication equipment. Through the adapter in the optical fiber cable distribution box, the optical signal is drawn out with the optical jumper to realize the function of optical wiring. It is suitable for the protective connection of optical cables and distribution pigtail and is also suitable for the use of optical fiber terminal points in optical fiber access networks. The plug and unplug durability life of its connector is > 1000 times. The full curvature radius control ensures that the curvature radius of the optical fiber is greater than 30mm at any position. Each fiber is clearly marked to avoid confusion that may be caused by disassembly during maintenance.

The optical fiber distribution box has a wide range of functions, including the introduction, fixation, and stripping protection of optical cables, fusion, and protection of optical fibers, storage of pigtails, storage and management of jumpers, fixed connection and cross-connection of optical fibers, etc. Value-added module units such as optical splitters, wavelength division multiplexers, etc. can be installed at the customer's request. It can also be used for the connection, use and management of optical cables between wiring rooms and equipment.
