Control circuit of optical transmitter
This optical-transceiver control circuit comprises a signal-generating means for generating a dummy signal that has substantially the same characteristics as an electrical signal generated from an optical signal inputted to an optical transceiver, a switching means for receiving. An optical transmitter acts as the interface between the electrical and optical domains by con-verting e ectrical signals to optical signals. 2Gbit/s, and gallium arsenide technology is used for their transmitter and receiver circuits. Laser Diode (LD) controller/driver IC's at gigabit data-rates typically use specially designed chipsets. Other components include a modulator for converting electrical data into optical form (if direct modulation is not used) and an electrical driving circuit for supplying current to the optical.
