Supported SFP Transceivers

Combination Fibre Channel/Gigabit Ethernet SFP Transceivers

The combination Fibre Channel/Gigabit Ethernet SFP transceivers from Cisco Systems are available in SWL or LWL versions for the Cisco MDS 9140 Switch and the Cisco MDS 9120 Switch. Both versions are 1-Gbps and 2-Gbps capable.

The combination SFP transceivers from Cisco Systems have LC connectors and comply with 1-Gbps and 2-Gbps Fibre Channel as defined in FC-PI 10.0 2 and Gigabit Ethernet as defined in IEEE 802.3z.

Transmission ranges are as follows:

Long wavelength: Up to 6.2 miles (10 km) on 9-micron single mode fiber

Short wavelength: Up to 328 yards (300 m) on 50-micron multi-mode fiber

Short wavelength: Up to 164 yards (150 m) on 62.5-micron multi-mode fiber For transceiver specifications, see Appendix C, “Cable and Port Specifications.”

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:

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.

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 Appendix C, “Cable and Port Specifications.”
