Transmitter Operation
The transceiver module receives 4 channels of 10 GB/s electrical data, which are
processed by a 4 channel Clock Data Recovery (CDR) IC that reshapes and reduces
the jitter of each electrical signal. Subsequently, a DML laser driver IC converts each
channel of the 4 electrical signals to optical signal from one of the 4 CWDM lasers.
The optical output power is maintained constant by an automatic power control (APC)
circuit. All of 4 optical signals are multiplexed by CWDM filters in a daisy-chain
configuration to form a single optical output of 40 GB/s.

Receiver Operation
The receiver section de-multiplexes the optical input of 40 GB/s signal into 4 optical
signals of CWDM wavelengths. Each optical signal is converted to electrical signal by
one of 4 PIN/TIA. All of the 4 electrical signals are feed to another CDR IC that
provides limiting amplification, and reshapes and retimes each electrical signal as one
of the 4 output channels.
