48 CHAPTER 2: INSTALLING THE SWITCH
Approved 100BASE-X
SFP Transceivers
The following list of approved 100Mbps SFP transceivers is correct at the
time of publication.
■ 3CSFP81 100BASE-FX
■ 3CSFP82 100BASE-LX10
■ 3CSFP85 100BASE-BX10-D
■ 3CSFP86 100BASE-BX10-U
SFP transceivers must be matched with the correct cable type as follows:
■ 100BASE-FX
Use this transceiver to connect 100Mbps SFP ports on the switch
directly to a multi-mode fiber-optic cable.
■ 100BASE-LX10
Use this transceiver to connect 100Mbps SFP ports on the switch
directly to a a single-mode fiber-optic cable.
■ 100BASE-BX10-D
Use this transceiver to connect 100Mbps SFP ports on the switch
directly to a single strand of a single-mode fiber-optic cable on the
opposite end of a link that is connected to a 100BASE-BX10-U
transceiver.
■ 100BASE-BX10-U
Use this transceiver to connect 100Mbps SFP ports on the switch
directly to a single strand of a single-mode fiber-optic cable on the
opposite end of a link that is connected to a 100BASE-BX10-D
transceiver.
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 and Fast Ethernet
SFPs supplied by 3Com. If the SFP transceiver is invalid it will not be
recognized by the switch.
