Introduction to the function and specifications of the optical fiber distribution box

The optical fiber goes to a small white box in each household to make the Internet speed fly. It is a magical existence, and the transfer station that transmits the optical fiber extension is called the optical fiber distribution box.

Optical fiber distribution box (ODB for short) is suitable for the wiring connection between optical cable and optical communication equipment. Through the adapter in the distribution box, the optical signal is drawn out with the optical jumper to realize the optical wiring function.

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. Its connector plug and unplug durability life > 1000 times. The full curvature radius control ensures that the curvature radius of the fiber at any position is greater than 30mm. Each fiber is clearly marked to avoid confusion that may be caused by 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, there is an obvious grounding mark at the grounding point.

The fiber optic distribution box is convenient for various connectors to be terminated and flexible to install. There are various specifications such as drawer type and fixed type; the modular optical fiber distribution box is more convenient to terminate and use more flexible; it supports the management of various optical fiber connectors, such as SC, LC, ST, MT-RJ, etc.; in 1U The space can be terminated with up to 48-core LC or MT-RJ (24 dual-port LC or 24 MT-RJ) optical fiber connectors; airtight management; front operation, quick and easy installation; height 1U, built-in two sets of optical fiber coiling rings; concave Concealed or flush mounted installation.

The optical fiber distribution box has a wide range of functions, including the introduction, fixing 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 termination, use and management of optical cables between wiring rooms and equipment.

From the speed of turtles to the speed of light, the emergence of optical fibers is a big step forward in the network process, and usually we only sigh at the smooth experience that optical fibers bring us, but turn a blind eye to the small white box in front of the door. Any great things are unknown. Without optical fiber distribution boxes, optical fibers cannot be popularized to every household. To be exact, optical fibers are as important as optical fiber distribution boxes. They are both important symbols of the advent of the Internet era.
