Abstract
The utility model discloses an optical receiving module. The optical receiving module includes a shell, and a PCB, an optical detector, an optical amplifier, an equalizer and a signal processor together installed in the shell. One end of the shell is provided with an optical interface while the other end of the shell is provided with a radio frequency output interface. The optical detector is connected with the optical interface and the PCB respectively. Further, the optical interface is coupled with an optical fiber connector. The optical receiving module provided by the utility model is small in size, high in PCB integration degree and low in space occupancy. Compared with the prior art, the radio frequency output signal level can be increased, the manufacturing technique can be simplified, the equipment investment can be economize and the cost can be reduced by adopting the optical receiving module provided by the utility mode.
Description
Technical field
The utility model relates to electronic applications, relates in particular to a kind of Optical Receivers.
Background technology
In optical fiber telecommunications system, the task of optical receiver is with the additional noise of minimum and distortion, recover after the Optical Fiber Transmission by the entrained information of light carrier, so the output characteristic concentrated expression of optical receiver the performance of whole optical fiber telecommunications system.The light signal of optical sender emission is after transmission, and amplitude fading, and impulse waveform not only is broadening also, and the effect of optical receiver is exactly the faint optical signal that detects through transmission, and amplification, shaping, the former transmission signal of regeneration.
In the prior art, the Optical Receivers volume is big, and the device in module takes up room more, does not concentrate, and is in use inconvenient.
The utility model content
The technical problems to be solved in the utility model has been to provide the Optical Receivers that a kind of volume is little, integrated level is high.
For solving the problems of the technologies described above, the utility model is realized by following scheme: a kind of Optical Receivers, described Optical Receivers comprises housing and is installed in housing interior pcb board, photo-detector, image intensifer, equalizer and signal processor, described housing one end is provided with optical interface, the other end is provided with radio frequency output interface, and described photo-detector connects optical interface, pcb board respectively.
Further, described optical interface and optical fiber splice coupling.
The utility model Optical Receivers volume is little, on pcb board the integrated level height, do not take up room, compare with prior art, can increase the radio frequency output signal level, simplify manufacture craft, save equipment investment, reduce cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the utility model Optical Receivers schematic diagram;
Fig. 2 is the utility model Optical Receivers theory diagram.
Embodiment
As shown in Figure 1, a kind of Optical Receivers, described Optical Receivers comprises housing 1 and is installed in pcb board, photo-detector, image intensifer, equalizer and signal processor in the housing 1, described housing 1 one ends are provided with optical interface 2, the other end is provided with radio frequency output interface 3, and described photo-detector connects optical interface 2, pcb board respectively.Described optical interface 2 and optical fiber splice coupling.
As shown in Figure 2, light signal after Optical Receivers receives by optical interface 2 is converted to the signal of telecommunication, through a line receiver, through a level translator signal is sent into multiplex circuit again, each road signal that the control by the sequence circuit in the multiplex circuit will receive separates and sends into each channel, through the conversion of synchronous asynchronous chip, add the initial sum position of rest, transfer it to level again, make it meet interface standard, can in computer or terminal, transmit.
The above only is preferred implementation of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in the scope of patent protection of the present utility model.
