CIRCUIT DEVICE WITH LASER DIODE FOR TRANSMITTING INFORMATION SIGNAL THROUGH TRANSMISSION ZONE |
摘要 |
A circuit arrangement for transmission of communication with a laser diode by way of a light waveguide wherein it is desired to reduce the optical transmitted power of the laser diode in order to lengthen its life duration and wherein in a receiving device a control signal is generated and is then fed back to the transmitting device through a return channel to control the output of the laser diode as a function of the received control signal. The invention assures that the optical transmitted power does not overload the laser diode which results in a considerable increase in the operating life time of the laser diode. The circuit arrangement can be used in light waveguide systems for optical communication or data transmission systems. |
