Abstract
The utility model relates to an optical-fiber MDF (main distribution frame) which comprises a frame body and an upper door header, wherein the upper door header is fixed at the top end of the frame body, an equipment side module and a line side module are respectively fixed on the front and rear sides of the frame body, horizontal jumped-fiber tanks are fixed between the equipment side modules, a cable fixed installing plate is fixed above the line side module, and a jumped-fiber adjusting device is fixed on a side of the frame body. According to the utility model, an effect of non-cross jumped-fiber routing can be achieved in the frame body, jumped fibers are all guided into on one side face layer by layer and then diverted layer by layer, thereby facilitating the operation, maintenance and management of the fibers; and multiple layers of independent horizontal jumped-fiber tanks are arranged between the equipment side modules, after frames are combined, the routing of jumping fibers between the frames is completed in the horizontal jumped-fiber tanks without entering into an optical-fiber channel in a machine room, thereby reducing the pressure of the channel in the machine room and being convenient for the dispatching management.
Description
Technical field
The utility model belongs to the communication facilities technical field, specifically relates to a kind of main distribution frame for fiber.
Background technology
Fibre distribution frame (ODF) is used for the Cheng Duan and the distribution of optical fiber telecommunications system local side backbone optical cable, can realize connection, distribution and the scheduling of fibre circuit easily.Present fibre distribution frame capacity is little, simple in structure, and what adopted is the jumping fiber management of plane formula, and the jumping fiber managerial confusion causes the crowded of cable passage.Large scale construction along with FTTx; Is the optical fiber of several thousand cores even several ten thousand cores enters into machine room, has produced a lot of problems thus: how optical fiber distributing handled? How are management and protection to optical fiber carried out? How is the test of optical fiber circuit carried out? This main distribution frame for fiber (OMDF) that just need design a kind of suitable FTTx solves above-mentioned variety of issue.
Summary of the invention
The utility model technical matters to be solved provides the main distribution frame for fiber that a kind of handled easily is safeguarded, can be reduced machine room conduit pressure.
For realizing the foregoing invention purpose; The utility model adopts following technical scheme: a kind of main distribution frame for fiber; Comprise support body and the last lintel that is fixed in the support body top, both sides are fixed with equipment side module and line side module respectively before and after the support body, are fixed with horizontal jumping fiber groove between the said equipment side module; Said line side module upper fixed has the optical cable mounting plate, and said support body avris is fixed with the jumping fiber regulating device.
Said equipment side module is made up of many groups line module, and each line module is 96 core unit frames.
Said line side module is made up of many groups in-line module, and each in-line module is 72 core unit frames.
The good effect of the utility model is following: the utility model in support body, can realize not having the cross-cross skip towpath by; Jumping fiber all successively imports in the same side, and successively shunting looks that from the side all jumping fibers all are vertical direction; Be a kind of " S " route, handled easily is safeguarded and management; The independently horizontal jumping fiber groove of multilayer is arranged between the equipment side module, and behind the frame, jumping fiber is accomplished route between frame in horizontal jumping fiber groove, need not advance the optical fiber conduit of machine room, reduce machine room conduit pressure and also make things convenient for management and running; The utility model adopts with the similar cable-management pattern of main frame (MDF) (MDF) and keeps existing maintainer's operating habit; Jumping fiber between jumping fiber, frame in outside line optical fiber, stern fast, the frame; In support body, adopt partition management; Both met and existing safeguarded system and custom, can realize again not having the cross-cross skip towpath by.The functions such as fixed connection and cross connection of storage and management, the optical fiber of storage, the jumping fiber of welding and protection, the tail optical fiber of stripping protection, optical fiber are fixed and are opened in the introducing that the utility model main distribution frame for fiber has an optical cable; Increment modular units such as optical branching device, wavelength division multiplexer can be installed according to requirement of client; Can accomplish transmission line terminal fused fiber splice distributing frame optical line by and all kinds of light device optical line of equipment end by between lane assignment, the wire jumper that can accomplish line scan pickup coil side and equipment end simultaneously is imbued with the memory function of length.
