●
Transmitter :In the transmit direction, the transceiver module receives a 10-Gbps electrical data signal and
transmits the data as an optical signal through an electrical to optical converter. The optical output power is
held constant by an automatic power control circuit. The transmitter also contains a Clock Data Recovery
(CDR) circuit. The function of this circuit is to attenuate and reshape any jitter received on the electrical
interface.
●
Receiver: In the receive direction, the transceiver module receives a 10-Gbps optical signal and converts it to
an electrical equivalent. The receiver contains a CDR circuit.
