A fiber optical distribution box (optical fiber termination box, ODB for short) is suitable for the wiring connection of optical cables and optical communication equipment. Through the adapter in the distribution box, optical jumpers are used to draw out optical signals to realize the optical wiring function. It is suitable for the protective connection of optical cables and distribution pigtails, and also suitable for the use of optical fiber terminal points in the optical fiber access network.

Performance description of fiber optic distribution box

Mechanical behavior

1. Connector plug-in durability life>1000 times.

2. The whole curvature radius is controlled to ensure that the curvature radius of the fiber at any position is greater than 30mm.

3. Each optical fiber is clearly marked, thus avoiding possible confusion caused by disassembly during maintenance.

4. Flame retardant: meet the requirements of GB5169.7 experiment A.

Electrical performance

1. Connector attenuation (insertion, interchange, repetition) ≤ 0.3dB;

2. Return loss: APC type ≥60dB, UPC type ≥50dB, PC type ≥40dB;

3. High-voltage protective grounding device:

4. Insulation resistance: ≥1000MΩ/500V (DC).

5. Withstand voltage: ≥3000V (DC)/1min, no breakdown, no arcing.

6. Grounding wire cross-sectional area: >6mm2, there is an obvious grounding mark at the grounding place.

Advantage of fiber optic distribution box

1. All kinds of joints are convenient for termination and flexible installation.

2. There are multiple specifications such as drawer type and fixed type.

3. Modular fiber distribution box termination is more convenient and uses more flexible.

4. Support the management of various optical fiber connectors, such as SC, LC, ST, MT-RJ, etc.

5. Up to 48-core LC or MT-RJ (24 dual-port LC or 24 MT-RJ), optical fiber connectors can be terminated in a 1U space.

6. Closed management;

7. The front operation, installation is quick and convenient.

8. 1U height, built-in two sets of optical fiber coiled rings.

9. Recessed or flush-mounted installation.

Scope of application of fiber optic distribution box

Optical cable introduction, fixing and stripping protection, optical fiber fusion and protection, pigtail storage, jumper storage and management, optical fiber fixed connection and cross-connection, and other functions. At the same time, optical splitters can be installed according to customer requirements. Value-added module units such as wavelength division multiplexers.
