Abstract
The utility model relates to the technical field of a communication device, and particularly to a multi-service optical transmission device. The utility model overcomes the problems of large device volume, larger machine room space taking and large energy consumption in the prior art. The utility model adopts a technical solution which is described as follows: the multi-service optical transmission device comprises a housing and a circuit board; the circuit board is provided with a plurality of general service slots and dedicated slots; and a power plate is inserted in the dedicated slots. Theutility model is characterized in that: the circuit board is horizontally provided on the bottom surface of the housing and is integrated with a digital cross connection module and a CPU module. Thegeneral service slots are connected with the digital cross connection module through a high-speed serial bus connection mode and are horizontally placed to the edge of the circuit board. The dedicatedslot is horizontally placed to the edge of the circuit board. The power plate is inserted in one dedicated slot. Compared with the prior art, the multi-service optical transmission device provided bythe utility model has the following advantages: 1. reduced volume; 2. low power consumption; and 3. high operation reliability.
Description
Technical field:
The utility model relates to the communication apparatus technical field, is specifically related to a kind of multi-service optical transmission device.
Background technology:
The multi-service optical transmission device is a kind of equipment that transmits on the optical fiber that multiple customer service is multiplexed into.The universal architecture of present this equipment is: comprise casing, facade relative with the operation facade on the casing is provided with wiring board (backboard), be vertically installed with a plurality of general professional slots and a plurality of dedicated slot in the circuit board, on dedicated slot, be inserted with digital crossover terminal pad, power supply disks and CPU dish respectively, on the general service slot, can select the corresponding business dish for use according to user's request.The problem that prior art exists is: equipment volume is big, generally highly is higher than 4U, takies more machine room space, is unfavorable for the layout of user's machine room; Because what miscellaneous service dish and slot all adopted is the parallel bus connected mode, so power consumption is big, the failure rate height, during so in a large number equipment operation, the problem that wastes energy seems more outstanding in operator's machine room.
Summary of the invention:
The utility model will provide a kind of multi-service optical transmission device, and is big to overcome the equipment volume that prior art exists, and takies more machine room space, simultaneously the big problem of energy consumption.
For overcoming the problem that prior art exists, the technical scheme that the utility model provides is: a kind of multi-service optical transmission device, comprise casing, wiring board, be provided with a plurality of general service slots and dedicated slot in the circuit board, be plugged with power supply disks on the dedicated slot, it is characterized in that: described wiring board is horizontally placed on the casing bottom surface, be integrated with digital crossover link block and CPU module on it, described general service slot connects with the digital crossover link block by the high-speed serial bus connected mode, and is horizontally placed on the edge of wiring board; Described dedicated slot is horizontally placed on the edge of wiring board; Described power supply disks is inserted on the dedicated slot.
Above-mentioned dedicated slot and the power supply disks of pegging graft on it are respectively arranged with two.Two power supply disks can be this equipment and provide and supply power with double circuit the support equipment operation.
Compared with prior art, the utility model has the advantages that:
1, volume-diminished: the original vertical level of having made into that plugs is plugged mode, and thickness only is 1.5U, can greatly save the equipment placement space in user's machine room.
2, power consumption is little: owing to substituted the parallel bus connected mode with the high-speed serial bus connected mode, therefore reduced the use energy consumption.
3, functional reliability height: the high-speed serial bus connected mode has been simplified slotting dish Connection Density, helps improving functional reliability and reduces system cost.
