CWDM Combination Fibre Channel/Gigabit Ethernet SFP Transceivers

All Fibre Channel and Gigabit Ethernet ports in the Cisco MDS 9200 Series support 1-Gbps/2-Gbps CWDM SFP transceivers. In addition, the Fibre Channel ports on Cisco MDS 9222i also support 4-Gbps 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. The OADM combines the wavelengths of the different outgoing signals into one composite send signal. The OADM also separates the received transmissions into the different wavelengths and sends them to the corresponding CWDM SFP transceiver.

For more information on the CWDM SFP transceiver specifications, see the “SFP and SFP+ Transceiver Specifications” section on page B-10.

Gigabit Ethernet SFP Transceivers

The 4-port and 8-port IP Storage services (IPS-4 and IPS-8) modules provide four or eight 1-Gigabit Ethernet ports that support Gigabit Ethernet SFP transceivers. The Gigabit Ethernet SFP transceivers have RJ-45 connectors and support Gigabit Ethernet (1-Gbps).

For more information on the Gigabit Ethernet SFP transceiver specifications, see the “SFP and SFP+ Transceiver Specifications” section on page B-10.

DWDM Fibre Channel SFP Transceivers

Fibre Channel ports on Cisco MDS 9222i support 2-Gbps DWDM SFP transceivers. The Cisco DWDM Fibre Channel SFP transceivers have LC connectors and support Fibre Channel (1-Gbps/2-Gbps). The DWDM SFP transceivers match the International Telecommunications Union (ITU) 100-Ghz wavelength grid and the wavelength plan of Cisco 100-Ghz ONS product family.

The DWDM SFP transceivers have the following capabilities:

•DWDM transmission can send and receive up to 32 laser wavelengths carrying different signals simultaneously on the same optical fiber by using an optical filter.

•ELWL signals can transmit over longer distances than LWL SFP transceivers.

For more information on the DWDM SFP transceiver specifications, see the “SFP and SFP+ Transceiver Specifications” section on page B-10.
