Description

FTTH fast wiring devices

Technical field

The utility model belongs to intelligent acess technical field, more particularly to a kind of FTTH fast wirings device.

Background technology

FTTH refers to optical network unit (ONU) being arranged at household user or enterprise customer, is removed in soft exchange series FTTD (fiber to the desk) is outside near the optical access network application type of user.FTTH notable technical characterstic is not only to provide more Big bandwidth, and enhance the transparency of the network to data format, speed, wavelength and agreement, relax to environmental condition and Power supply etc. requires, simplifies maintenance and installation.

Although present Mobile Communication Development speed is surprising, because its bandwidth is limited, terminal volume can not possibly be too big, display screen The factors such as curtain is limited, people still pursue the relative fixed terminal being dominant of performance, that is, wish to realize fiber to the home.Optical fiber arrives The glamour at family is that it has great bandwidth, and it is that solve from Internet backbone to user's desktop " last one kilometer " bottle The preferred plan of neck phenomenon.Optical fiber is directly connected to user house, because its bandwidth, wavelength and transmission technology species all do not limit System, suitably incorporates various new business, is optimal business transparent network, is the final mode of access network development.And with skill The update of art, fiber-to-the-home cost substantially reduce, and can drop to soon suitable with DSL and HFC nets, and this makes FTTH practicality Change is possibly realized.

But in FTTH processs of construction, the mode of traditional wiring is to register one's residence or pass through by light current well (hidden pipe) inside building The outer fly line of building is registered one's residence, and above two scheme wastes time and energy and outward appearance is in disorder unsightly.The wire laying mode that prior art uses because Fibre junction point is very scattered, while is limited to the factors such as cost and site environment, therefore the main mode connect soon using scene Optical fiber is continued；But scene connects mode and has that fault rate is high, service life is short, reliability is low and what loss was big lacks soon Point, shorten coverage distance therefore limit its use range.

To solve the above problems, Authorization Notice No. is CN205809372U Chinese patent, it is quick to disclose a kind of FTTH Laying system multi-user's light allocation unit device, it includes optical cable, light end box, fiber active linker and tail optical fiber, light end box Including upper lid, lower cover, mounting plate, it is connected between upper lid, lower cover using rotary structure and buckle, mounting plate leads to Screw is crossed on lower lid, mounting plate is used to carrying and fixing fiber adapter；The joints of optical fibre are assemblied in optical fiber and fitted On orchestration, jumping fiber is accessed for connecting user.Although the device simplifies FTTH construction procedures, but problems be present：1、 In use for some time, the buckle on upper lid may be plastically deformed or wear and fail plastic material, it is also possible to Fracture, causes lid to cover completely on lower lid, and the light electric wire and joint for causing tray interior are exposed to outside, influence light The transmission of optical fiber signaling；2nd, because fiber cores are very thin, also it is easy to break, a part of optical fiber needs directly to wear from lower cover when installation Cross, another part optical fiber needs to carry out a point fibre through fixed plate, fixed plate is fixed on lower lid by screw, for construction For, difficulty is very big, extremely inconvenient.

Utility model content

The purpose of this utility model is to provide that a kind of clamping is firm, efficiently FTTH fast wiring devices easy to assembly.
