Chapter 1 Product Overview
Supported SFP Transceivers
Supported 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
Note Switches running Cisco MDS SAN-OS Release 1.1(1a) 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.
For the list of supported SFP transceivers, see the Cisco MDS 9000 Family Release Notes. For more
information about a specific Cisco SFP transceiver, see the “SFP Transceiver Specifications” section on
page B-4. SFP transceivers can be ordered separately or with the Cisco MDS 9100 Series.
Note Use only Cisco SFP transceivers on the Cisco MDS 9100 Series. 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 Fibre Channel SFP transceivers are available in SWL or LWL versions. Both versions are
1-Gbps/2-Gbps capable. The Cisco MDS 9124 Switch supports 4-Gbps Fibre Channel SFP transceivers.
Cisco Fibre Channel SFP transceivers have LC connectors and comply with 1-, 2-, and 4 Gbps
Fibre Channel standards as defined in FC-PI 10.0 2.
Transmission ranges for 2 Gbps 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
Transmission ranges for 4 Gbps are as follows:
• Long wavelength: Up to 6.2 miles (10 km) on 9-micron single-mode fiber
• Short wavelength: Up to 546 yards (500 m) on 50-micron multi-mode fiber
• Short wavelength: Up to 328 yards (300 m) on 62.5-micron multi-mode fiber
