Chapter1 Product Overview
Supported SFP Transceivers
Supported SFP Transceivers
The following types of SFP transceivers are available from Cisco and are
supported on the Cisco MDS 9216:
•Fibre Channel SFP transceivers, in either short wavelength (SWL) or long
wavelength (LWL)
•Combination Fibre Channel / Gigabit Ethernet SFP transceivers, in either
SWL or LWL
•Combination Fibre Channel / Gigabit Ethernet CWDM SFP transceivers,
which can be used for extended long wavelength (ELWL) transmission or for
coarse wavelength-division multiplexing (CWDM)
Note Combination Fibre Channel / Gigabit Ethernet SFP transceivers are supported for
switches running Cisco MDS SAN-OS Release 1.1(1a) or later.
SFP transceivers are field-replaceable. You can use any combination of SFP
transceivers that are supported by the switch. The only restrictions are that SWL
transceivers must be paired with SWL transceivers, LWL transceivers with LWL
transceivers, and the cable must not exceed the stipulated cable length for reliable
communications.
Refer to the release notes for the list of supported SFP transceivers. For more
information about a specific Cisco SFP transceiver, refer to the SFP transceiver
documentation.
SFP transceivers can be ordered separately or with the Cisco MDS 9216.
Note Use only Cisco SFP transceivers on the Cisco MDS 9216. Each Cisco SFP
transceiver is encoded with model information that enables the switch to verify
that the SFP transceiver meets the requirements for the switch.

Fibre Channel SFP Transceivers

Cisco’s Fibre Channel SFP transceivers are available in short wavelength (SWL)
or long wavelength (LWL) versions. Both of these versions are 1 Gbps / 2 Gbps
capable.
