  • Single send-receive optical head for transmission and reception of data by optical system, and associated switching circuit
    Patent number: 5349462
    Abstract: An optical head incorporating a single opto-electronic component and a laser device for transmitting and receiving data on a single optical fiber. The use of a single laser device for both sending and receiving data is made possible by a switching circuit, controlled by two transistors which forward-bias the laser device for transmission and reverse-bias the laser device for reception. Such a device may find particular application to data transmission on an optical path, and particularly between 1 and 10 GHz.
