What's Fiber Terminal Box?
Optical fiber terminal box (optical fiber distribution box, ODB) is suitable for the wiring connection of optical cable and optical communication equipment. Through the adapter in the distribution box, the optical signal is led out by the optical jumper to realize the optical wiring function. Connecting cable adapted to protect the pigtail and the wiring, also applies to the optical fiber access network fiber optic terminal points employed.
Introduction
Fiber terminal box is used to connecting cable and protect the pigtail and the wiring, also applies to the optical fiber access network.
Mechanical behavior
Connector plugging durability life>1000 times.The curvature radius of the whole process is controlled to ensure that the radius of curvature of the fiber at any position is greater than 30mm.Each optical fiber is clearly marked, so as to avoid the confusion that may be caused by disassembly during maintenance.Flame retardant: Meet the requirements of GB5169.7 Test A.
Electrical performance
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.The cross-sectional area of the grounding wire: >6mm2, and there is an obvious grounding mark at the grounding place.
Advantages
All kinds of joints are convenient for termination and flexible installation.There are multiple specifications such as drawer type and fixed type;Modular optical fiber distribution box is more convenient for termination and more flexible to use;Support the management of various optical fiber connectors, such as SC, LC, ST, MT-RJ, etc.;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;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 fiber 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. Fiber terminal box is used for the termination, use and management of optical cables in wiring closets and equipment rooms.
