TRANSMITTER AND RECEIVER FOR TRANSCEIVING OPTICAL SIGNALS

摘要

A transmitter for transmitting an optical signal based on a baseband signal, including an up-transformer for up-transforming the baseband signal to obtain a bandpass signal and a converter for converting the bandpass signal into a signal having a DC-offset. The transmitter further includes a modulator for modulating a light source with the signal having the DC-offsets to transmit the optical signal.
