Abstract
Circuitry for controlling a diode optically coupled to an optical fiber suitable for transmitting digital light signals therethrough. The circuitry includes a temperature compensated driver when operating in the transmit mode and receiving circuitry for conditioning and amplifying electrical signals generated by the diode when it operates in a photodetection mode. A sweep circuit is provided for isolating amplifiers in the receiving circuitry and for discharging residual charge left in the diode during the transmission mode thereby reducing the signal-to-noise ratio.
