Fibre Channel SFP Transceivers

Cisco Fibre Channel SFP transceivers are available in SWL or LWL versions. Both of these versions are 1-Gbps/2-Gbps/4-Gbps capable. Cisco Fibre Channel SFP+ transceivers are available in SWL or LWL versions. Both of these versions are 2-Gbps/4-Gbps/8-Gbps capable.

Cisco Fibre Channel SFP transceivers have LC connectors and comply with 1-Gbps/2-Gbps/4-Gbps Fibre Channel standards as defined in FC-PI 10.0 2. Cisco Fibre Channel SFP+ transceivers have LC connectors and comply with 2-Gbps/4-Gbps/8-Gbps Fibre Channel standards as defined in FC-PI-4.

For more information about Fibre Channel SFP and SFP+ transceiver specifications, see the “SFP and SFP+ Transceiver Specifications” section on page D-22.

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. Both of these versions are 1-Gbps/2-Gbps capable.

The combination SFP transceivers from Cisco Systems have LC connectors and comply with

1-Gbps/2-Gbps Fibre Channel as defined in FC-PI 10.0 2 and Gigabit Ethernet as defined in IEEE 802.3z.

For more information about Fibre Channel/Gigabit Ethernet SFP transceiver specifications, see the “SFP and SFP+ Transceiver Specifications” section on page D-22.

CWDM Combination Fibre Channel/Gigabit Ethernet SFP Transceivers

The Cisco CWDM SFP transceivers have LC connectors and support Gigabit Ethernet and

1-Gbps/2-Gbps Fibre Channel. They match the wavelength plan of Cisco CWDM GBICs and Cisco CWDM optical add/drop multiplexers (OADMs). Cisco 4-Gbps CWDM SFP transceivers are also available.

CWDM SFP transceivers are used in the following 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 about CWDM SFP transceiver specifications, see the “SFP and SFP+ Transceiver Specifications” section on page D-22.

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).
