Abstract
The utility model relates to a small box type PLC (Programmable Logic Control) optical divider for FTTX (Fiber To The X) network. The small box type PLC optical divider comprises a box body with the front face open and a box cover matched with the box body, wherein a PLC optical divider core body and a fiber winding baffle plate are mounted in the box body; and an input hole and an output hole are formed in one side of the box body. The small box type PLC optical divider is characterized in that the dimension is 100*80*10 mm after the box body and the box cover are closed. The small box type PLC optical divider has the following advantages that 1, compared with the existing product with the same splitting ratio, the volume of the small box type PLC optical divider can be reduced by more than 50%, and the small box type PLC optical divider is highly integrated so that the space and the limited resources are saved, the space for mounting the optical divider in FTTX is reduced and the requirements of the machine room and FTTX construction in the future also are met; and 2, due to small volume, the small box type PLC optical divider is flexible and convenient to use and mount so that the mounting and maintenance of the optical divider in FTTX construction are more convenient and the fabrication cost of the box is reduced.
Description
Technical field
The utility model relates to a kind of optical communication passive device, is specifically related to a kind of small-sized boxlike PLC optical branching device for the FTTX network.
Background technology
Along with building progressively, FTTX (Optical Access Network) launches, for building up Full Fibre Network, except the various structure optical distribution cable of needs, leading in cable are realized continuing of fiber optic network and are reallocated, in E-PON, G-PON technology, also need in a large number optical branching device finally to complete fiber-to-the-home purpose.But the conduit resource in city is nervous at present, lays space and the resource-constrained of FTTX equipment in the city.Therefore with PLC optical branching device device miniaturization, saving space and the resource of installing, is the developing direction of Passive Optical Components.Use at present 1/2 * 16 or 1/2 * 32 more boxlike PLC optical branching device, its package dimension is generally 120 * 80 * 18 or 141 * 115 * 18, and stern fast is generally φ 2.0mm or φ 3.0mm.The volume of such optical branching device is large, is difficult to satisfy following machine room and residential quarter FTTX design and construction requirement.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of small-sized boxlike PLC optical branching device for FTTX for the deficiency that above-mentioned prior art exists, and its volume is little, saves the space, and is easy to install and use and cost of manufacture is low.
The utility model for the technical scheme that the problem that solves above-mentioned proposition adopts is: include the positive box body that opens wide and with the lid of box body phase configuration, be installed on PLC optical branching device core body in box body and around fine baffle plate, one side of box body offers input hole and delivery outlet, it is characterized in that being of a size of 100 * 80 * 10mm after described box cover encapsulation.
Press such scheme, install PLC optical branching device core body above in box body.
Press such scheme, describedly comprise around fine baffle plate the upper and lower bending baffle plate that is arranged in box body, upper and lower bending baffle length is 25 ~ 35 mm, and spacer is 30 ~ 40mm.
Press such scheme, describedly also comprise around fine baffle plate the right side baffle plate that is arranged in box body, the spacer of right side baffle plate and right plate is 5 ~ 10mm.
Press such scheme, described input hole and delivery outlet are opened on the right plate of box body, and correspondence offers interior input hole and interior delivery outlet on the baffle plate of right side.
Press such scheme, described input hole is 1, is opened in above right plate; Described delivery outlet is 32, is opened in below right plate, and 2 rows before and after minute, 16 of every rows, each delivery outlet spacer equates.
Press such scheme, four jiaos are provided with screw in box body, and four jiaos of correspondences of lid are offered the connection counterbore, by screw, lid are connected with box body.
The beneficial effects of the utility model are: 1, the product of relatively existing same splitting ratio, the utility model volume can dwindle more than 50%, integrated level is high, space and limited resources have been saved, reduce the space that is used for installing optical branching device in FTTX, also satisfied the requirement that following machine room and FTTX build; 2, because volume is little, use and install more flexibly and easily, make in the construction of FTTX light installation and maintenance along separate routes more convenient, and reduced the cost of manufacture of box.
