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.
