Fiber Optical Distribution Box

Fiber Optical Distribution Box

The optical fiber distribution box, abbreviated as ODB, 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 achieve optical wiring functions. 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. Its connector plugging 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.

Performance description

Mechanical behavior

Closed management;

Front operation, installation is quick and convenient;

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

Recessed recessed or flush mounted installation.

Scope of application

Optical cable introduction, fixing and stripping protection, optical fiber splicing 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.

Used for the termination, use and management of optical cables in wiring closets and equipment rooms.

Optical fiber distribution box application construction

1. Lead the optical cable to the position of the optical cable fixing plate at the back of the optical cable distribution box.

2. Cut the end of the optical cable to a length of about 1m. Then take an appropriate length (about 1500mm), peel off the outermost sheath, insert the end of the ground wire barbed piece into the stripping point of the optical cable (slightly cut the sheath with a blade), and wrap it tightly with a film to ensure contact with the optical cable armored steel tape reliable. Take the metal reinforcing core about 85mm from the stripping point of the optical cable and cut off the remaining part, and fix the metal reinforcing core on the steel wire fixing seat, and tighten the optical cable with a hose clamp to make it stable. After the stripped optical cable bundle tube is replaced with a PVC protective hose, it is pre-coiled on the take-up area and a welding disc is introduced, and the PVC protective hose is fixed on the welding disc with a cable tie.

3. Take an appropriate length of optical fiber pigtail (usually 2 meters), paste a sticker on both ends, fix one end of the pigtail to the adapter of the 6-port adapter mounting plate, and lead the other end to the entrance of the splice tray. The pigtail is fixed on the splice disc.

4. Move the back box cover together with the splicing disc to the outside of the box for fiber splicing. The splice point is protected by a heat-shrinkable tube and fixed in the heat-shrinkable tube holder of the optical fiber splicing disc, covered with a protective cover. After completion, fix the back box cover on the box body and straighten out and fix the optical fiber.
