Long-Distance, High-Bandwidth Transport Configuration
Figure 1-3
Catalyst 3560 switches have Coarse Wave Division Multiplexer (CWDM) fiber-optic SFP modules
installed. Depending on the CWDM SFP module, data is sent at wavelengths from 1470 to 1610 nm. The
higher the wavelength, the farther the transmission can travel. A common wavelength used for
long-distance transmissions is 1550 nm.
The CWDM SFP modules connect to CWDM optical add/drop multiplexer (OADM) modules over
distances of up to 393,701 feet (74.5 miles or 120 km). The CWDM OADM modules combine (or
multiplex) the different CWDM wavelengths, allowing them to travel simultaneously on the same
fiber-optic cable. The CWDM OADM modules on the receiving end separate (or demultiplex) the
different wavelengths.
For more information about the CWDM SFP modules and CWDM OADM modules, refer to the Cisco
CWDM GBIC and CWDM SFP Installation Note.
