100FX SFP Module for Gigabit Ethernet Ports
The 100FX SFP module for Gigabit Ethernet (GE) ports (Model # 10063) provides optical links up to 2
km long using multimode fiber cable. The 100FX SFP for GE ports conforms to the 100FX-MMF
standard.
The 100FX SFP modules are supported in the following Extreme Networks switches:
● BlackDiamond 8800 series
■ G24x I/O module
■ MSM-G8x module
■ G48Xa I/O module
● Summit X250e series
■ Summit X250e-24t, X250e-24p, X250-48t, X250e-48t: combination ports only
■ Summit X250e-24x: all ports
● Summit X450a-24x switch: ports 5 through 24; not supported on combination ports
● Summit X450a series: not supported on combination ports
Dual-speed 100FX/1000LX SFP Module
The dual-speed 100FX/1000LX SFP module operates at either 100 Mbps or 1000 Mbps over SMF links
up to 10 km long. Operating at 100 Mbps, the dual-speed SFP conforms to the 100BASE-LX standard.
Operating at 1000 Mbps, the dual-speed SFP conforms to the 1000BASE-LX standard.
The dual-speed 100FX/1000FX SFP modules are supported in the following Extreme Networks
switches:
● BlackDiamond 8800 series
● BlackDiamond 12800 series
● Summit X150 series
● Summit X250e-24t, X250e-24p, X250e-48t, X250e-48p switches: combination ports only
● Summit X450-24x switch: ports 5 through 24 (not supported on combination ports)
● Summit X450a-24x, X450a-24xDC switches: ports 1 through 20 (not supported on combination ports)
Optical Budget Calculation
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.
