Abstract
The utility model discloses a single fiber two-way receiving and transmitting module which mainly comprises a laser diode and a photoelectric diode, wherein a single fiber collimator is arranged in front of the laser diode; a sloping membrane is arranged between the single fiber collimator and the laser diode. One side of the membrane, which corresponds to the laser diode, is plated with a high-transmission film; the other side of the membrane corresponds to the photoelectric diode, and is plated with a high-transmission and a high-reflecting film. The structure can directly modulate electrical signals to the laser diode; light signals after modulated are coupled in an optical fiber and are transmitted out. Simultaneously, the structure receives input signals on the optical fiber and couples the signals into the photoelectric diode to be converted into electrical signals; two-way light signal communications in the same optical fiber is realized. The utility model has the advantages of small volume, compact and simple structure and favorable stability.
