CWDM Combination Fibre Channel/Gigabit Ethernet SFP Transceivers

All Fibre Channel and Gigabit Ethernet ports in the Cisco MDS 9100 Series support CWDM SFP
transceivers.
The Cisco CWDM SFP transceivers have LC connectors and support both Gigabit Ethernet and Fibre
Channel (1-Gbps / 2-Gbps). They match the wavelength plan of Cisco CWDM GBICs and Cisco CWDM
optical add/drop multiplexers (OADMs).
CWDM SFP transceivers can be used in two ways:
•
•
There are eight different "colors" of CWDM SFP transceivers, one for each fixed wavelength. The fiber-
optic cables from the CWDM SFP transceivers must be connected to an OADM, which combines the
wavelengths of the different outgoing signals into one composite send signal, and separates the received
transmissions into the different wavelengths and sends them to the corresponding CWDM SFP
transceiver.
For detailed transceiver specifications, see
Cisco MDS 9100 Series Hardware Installation Guide
1-18
CWDM transmission can send and receive up to eight laser wavelengths carrying different signals
simultaneously on the same optical fiber, using an OADM.
ELWL signals can transmit over longer distances than LWL SFP transceivers.
