Overview
The 25G SFP28 CWDM 10KM module optical connection is duplex LC and
shall be compatible with 25G SFP28 pluggable and backward
compatible with legacy 10G SFP+ pluggable. The SFP28 LR CWDM module
is a dual directional device with a transmitter and receiver plus a
control management interface (2-wire interface) in the same
physical package. 2-wire interface is used for serial ID, digital
diagnostics and module control function.
