General Description
The CFP-40GBASE-ER4  is  a  40Gb/s  transceiver  module  for  optical  communication
applications compliant  to  40GBASE-ER4 of  the  IEEE  P802.3ba standard.  The module
converts 4  inputs  channels  of  10Gb/s electrical  data to 4  CWDM optical  signals and
then  multiplexes  them  into  a  single  channel  for  40Gb/s  optical  transmission.
Reversely on the receiver side, the module de-multiplexes a 40Gb/s optical input into
4  CWDM  channels  of  optical  signals and  then converts them to electrical  data for 4
output channels.
The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 1331 nm
as  members  of  the  CWDM  wavelength  grid  defined  in  ITU-T  G694.2.  For  SMF
applications, the transceiver module has an operating range up to 40km SMF.
The CFP-40GBASE-ER4 is  designed  with  form  factor,  optical/electrical  connection  and
MDIO interface according to the CFP Multi-Source Agreement (MSA). The innovative
design  has  all  the  fibers inside  the  CFP  package  configured  without  any  splicing  or
non-permanent connector. Also, fiber routines are neatly organized and fixed inside a
stainless  steel  container. For  mechanical  and  environmental  reliability,  the  WDM
sections are  aligned and  secured to  the container  by  laser  welder, and  then  aligned
and affixed with each high power CWDM laser or APD/TIA TO to form an integrated
structure of TOSA or ROSA.
 
Functional Description
The CFP-40GBASE-ER4 contains  a  duplex Straight LC  connector for the  optical  interface
and a 148-pin connector for the electrical interface. The chart in section 3 shows the
functional block diagram of the CFP-40GBASE-ER4 CFP Transceiver.
