Table 14 lists the specifications for the dual-speed 100FX/1000LX SFP module for Gigabit Ethernet (GE)
ports. Operating at 100 Mbps, the dual-speed SFP conforms to the 100BASE-LX10 standard. Operating
at 1000 Mbps, the dual-speed SFP conforms to the 1000BASE-LX standard.
NOTE
The 100FX/1000LX SFP module complies with the 100FX-SMF standard. To use the 100FX/1000LX SFP module in
100FX-MMF operation, a minimum attenuation of 6 dB is required. After the SFP module is installed, connect a
6-dB attenuator to the transmitter side (Tx) of the SFP module. Next, connect the attenuator to the single-mode end
of a mode conditioning patch cord. The mode conditioning patch cord transitions the SFP module from SMF to MMF
operation.
Table 16 lists specifications for the LX100 SFP module.
