DWDM-40C  

Rev. 

 

1 Product overview 

The Flashlink DWDM-40C is a set of optical modules for multiplexing and demultiplexing 
100GHz spaced DWDM (Dense Wavelength Division Multiplexed) signals. The modules are 
bidirectional, so they work as both multiplexer and demultiplexer at the same time. 

A DWDM-40C consists of one DWDM-40C-A and one DWDM-40C-B, which when used 
together, provide an optimal link loss by stepping the insertion loss profiles in one end point 
complementary to the other.
