Abstract
The utility model discloses a kind of cold joint type without jump optical cable distribution box, it comprises backbone optical cable (1), optical branching device (2), optical-fibre channel (3), deposits fine device (4), optical distribution cable (5) and optical cable fixed head (6) around fibre, wherein, optical fiber in backbone optical cable (1) docks in optical branching device (2) with the tail optical fiber of optical distribution cable (5), and backbone optical cable (1) and optical distribution cable (5) are fixedly mounted in cross-connecting box by optical-fibre channel (3).The beneficial effects of the utility model are: this device adopts the principle of optical fiber cold connection to use optical fiber cold joint to realize optical fiber and optical fiber docking in fiber cable cross connection box, without the need to using heat sealing machine, reduce the difficulty of field operation, reduce requirement that fiber alignment configures fiber cable cross connection box and cross-connecting box volume can be reduced, shorten the process time of fiber alignment and reduce production cost, be easy to installation and maintenance.
Description
Technical field
The utility model relates to fiber cable cross connection box, and particularly a kind of cold joint type is without jump optical cable distribution box.
Background technology
Fiber cable cross connection box a kind ofly provides the handing-over equipment of optic fiber distribution, jumper connection for trunk layer optical cable, wiring layer optical cable.After optical cable leading in cable cross-connecting box, through fixing, termination, join fibre after, use jumping fiber to be communicated with wiring layer optical cable by trunk layer optical cable.
Along with the fast development of optical fiber communication, be used widely without jump optical cable distribution box.Existing fiber cable cross connection box adopts the mode Cheng Duan of hot melt, to the equipment requirement used during welding and operation requirements all higher, cost remains high, and to carry out docking in fiber cable cross connection box be generally operate in the wild, adopts the method Cheng Duan of hot melt to too increase operation easier.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, there is provided a kind of and be easy to install, the little cold joint type of light wave loss is without jump optical cable distribution box, this device uses optical fiber cold joint to realize optical fiber and optical fiber or optical fiber and tail optical fiber docking in fiber cable cross connection box by adopting the principle of optical fiber cold connection, without the need to using heat sealing machine, reducing the difficulty of field operation, reduce requirement, the process time shortening fiber alignment that fiber alignment configures fiber cable cross connection box and reduce production cost.
The purpose of this utility model is achieved through the following technical solutions: a kind of cold joint type is without jump optical cable distribution box, it comprises backbone optical cable, optical branching device, optical-fibre channel, deposits fine device, optical distribution cable and optical cable fixed head around fibre, wherein, optical fiber in backbone optical cable docks in optical branching device with the tail optical fiber of optical distribution cable, and backbone optical cable and optical distribution cable are fixedly mounted in cross-connecting box by optical-fibre channel.
Optical fiber in described backbone optical cable docks by using optical fiber cold joint to complete in optical branching device with the tail optical fiber of optical distribution cable.
The utility model has the following advantages: the utility model adopts the principle of optical fiber cold connection to use optical fiber cold joint to realize optical fiber and optical fiber docking in fiber cable cross connection box, without the need to using heat sealing machine, reduce the difficulty of field operation, reduce fiber alignment and also can reduce cross-connecting box volume to the requirement that fiber cable cross connection box configures, shorten the process time of fiber alignment, reduce the volume of fiber cable cross connection box, save for the manufacture of backbone optical cable fusion joining disk, the material of optical distribution cable fusion joining disk and optical distribution cable tail optical fiber memory block and reduce production cost, and by using optical fiber cold joint to dock, fiber alignment place has axis to be adjacent to power, during fiber alignment, two fiber end face gaps are almost nil, so junction loss is usually less than≤0.3dB, even be less than≤situation of 0.1dB also often occurs, owing to not using optical fiber to mate cream, there is not the loss of optical fiber coupling cream, pollution and problem of aging, very good also to determine the stability continued very good for the reliability of fiber gripper in addition.
