Chapter 1 Product Overview
Supported SFP and SFP+ Transceivers
Supported SFP and SFP+ Transceivers
The following types of SFP transceivers are available from Cisco Systems and are supported on the
Cisco MDS 9100 Series:
•
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 course wavelength division multiplexers (CWDM)
SFP transceivers, which can be used for extended long wavelength (ELWL) transmission or for
CWDM
•
Combination Fibre Channel/Gigabit Ethernet dense wavelength division multiplexers (DWDM)
Note
Switches running Cisco MDS SAN-OS Release 1.1(1a) or later and MDS NX-OS Release 4.1(1b) or
later support combination Fibre Channel/Gigabit Ethernet SFP transceivers.
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, and LWL transceivers with LWL transceivers, and the cable must not exceed the stipulated
cable length for reliable communications.
SFP tranceivers can also be used in extended distances, but it would depend on the allocation of available
Buffer-To-Buffer (B2B) credits on specific ports in the switch. For more information on Buffer-to-Buffer
(B2B) credits, see the Configuring Interface Buffers chapter in the Cisco MDS 9000 Family NX-OS
Interfaces Configuration Guide.
For the list of supported SFP transceivers, see the Cisco MDS 9000 Family Release Notes for Cisco MDS
NX-OS Releases. For more information about a specific Cisco SFP transceiver, see the
“SFP Transceiver
Specifications” section on page B-6
. SFP transceivers can be ordered separately or with the Cisco MDS
9100 Series.

The flashing green light turns on automatically when an external loopback is detected that causes the interfaces to be isolated.
The flashing green light overrides the beacon mode configuration. The state of the LED is restored to reflect the beacon mode
configuration after the external loopback is removed.
