About DWDM

Dense Wavelength-Division Multiplexing (DWDM) multiplexes multiple optical carrier signals on a single
optical fiber. DWDM uses different wavelengths to carry various signals.
To establish a DWDM link, both ends of an Inter Switch Link (ISL) need to be connected with DWDM SFPs
(small form-factor pluggable) at each end of the link. To identify a DWDM link, Fabric Manager discovers
the connector type on the Fiber Channel (FC) ports. If the ISL link is associated with the FC ports at each
end, then the FC port uses DWDM SFP to connect the links.
Fabric Manager Server discovers FC ports with DWDM SFPs and the ISLs associated with the FC ports. The
Fabric Manager Client displays ISL with DWDM attribute on the topology map.
Note
The Fabric Shortest Path First (FSPF) database only displays an ISL link, which is connected with DWDM
SFPs at both ends.

Configuring X2 DWDM Transceiver Frequency

To configure X2 DWDM transceiver frequency for a module, follow these steps:
Step 1
switch# config terminal
Enters configuration mode.
Step 2
switch(config)# module 1 transceiver-frequency x2-eth
Configures the link to fuction as X2 Ethernet.
