Cisco Enhanced Wave Division Multiplexing
Optical System Installation Note
This document provides installation instructions for the Cisco Enhanced Wave Division Multiplexer
(EWDM) passive optical system. The EWDM system combines 1 GB Coarse Wave Division
Multiplexing (CWDM) connections using SFPs and GBICs with 10 GB Dense Wave Division
Multiplexing (DWDM) connections using XENPAK, X2, or XFP DWDM modules. These DWDM
connections can either be passive or boosted to allow a longer range for the connection. The EWDM
passive optical system product numbers are listed in
