Light transmitting module and related light receiving module

The optical transmitting module is to receive the outer electric signal and convert it into optical signal to send it out, which comprises of the first illuminant generator, the second illuminant generator the optical fiber and the wave combiner. The wave combiner is to couple the light of different wavelength. The optical receiving module is to receive the optical signal from the optical fiber and covert it into the electric signal and send it out, it comprises of the first and second optical detector, the optical wave separator, which couples the light of different wave length into the first and second optical detectors.
