SFP Operation

Approved
1000BASE-X SFP
Transceivers
The following sections describes how to select and use an SFP transceiver
in an SFP port.
The approved Gigabit Ethernet SFP transceivers include:
3CSFP91 SFP (1000BASE-SX)
■
3CSFP92 SFP (1000BASE-LX)
■
3CSFP93 SFP (1000BASE-T)
■
3CSFP97 SFP (1000BASE-LH70)
■
3Com may approve additional SFP transceivers following the publication
of this document. The latest list of approved SFP transceivers for the
Switch 5500 Family is available on the 3Com Web site, at:
http://www.3com.com
You must match SFP transceivers with the correct cable type as follows:
1000BASE-SX SFP transceiver
■
Use this transceiver to connect Gigabit Ethernet SFP ports on the
switch directly to a multimode fiber-optic cable.
1000BASE-LX SFP transceiver
■
Use this transceiver to connect Gigabit Ethernet SFP ports on the
switch directly to a single-mode fiber-optic cable or to a multimode
fiber using a conditional launch cable.
1000BASE-LH70 SFP transceiver
■
Use this transceiver to connect Gigabit Ethernet SFP ports on the
switch directly to a single-mode fiber-optic cable.
1000BASE-T SFP transceiver
■
This transceiver uses Category 5 copper cabling with RJ-45 connectors
and supports segment lengths of up to 100 m (328 ft).
If the SFP transceiver is faulty, it will not operate within the switch. See
"Solving Hardware Problems" on page 83.
3Com recommends that you only use Gigabit Ethernet SFPs supplied by
3Com. If the SFP transceiver is invalid it will not be recognized by the
switch.
