Embodiment
The core concept of the optical module dual transmitting and receiving device that the utility model proposes is: will play the optical device of same function in the prior art on both direction, as optical receiver, reception processing unit, transmission processing unit or the like, be integrated on the optical fiber transceiver module, optical module dual transmitting and receiving device operation principle block diagram of the present utility model as shown in Figure 2.Optical splitter is placed on optical module inside among Fig. 2, also can be placed on the optical module outside.
Light-receiving among Fig. 2 selects module to describe in detail by following two embodiment.
First embodiment theory diagram of the present utility model as shown in Figure 3, details are as follows for the concrete course of work:
At sending direction, the Service Processing Unit of processor directly sends to signal the transmission processing unit of optical fiber transceiver module, sending processing unit carries out obtaining sending light signal after signal processing and the electric light conversion, send light signal and carry out beam split through optical splitter, obtain the identical light signal of two-way, to east orientation and western, send out respectively thereby realization is two to transmission.At receive direction, the light signal of identical services is being carried to two-way in east orientation and west, be input to the two path signal input high speed alternative electric switch that optical receiver a and optical receiver b carry out obtaining after the opto-electronic conversion respectively, high speed alternative electric switch selects wherein one the tunnel as the main business signal, and other one the tunnel as being equipped with service signal.From the service signal of high speed alternative electric switch output through receiving incoming traffic processing unit behind the processing unit, thereby the choosing that has realized signal is received.
