The information in this guide about hardware platform support for each type of SFPs is current as of
the date this guide was published. Support for specific SFP types may have been added to other
switches or I/O modules besides those listed in this guide. For current information about hardware
support and the minimum required software for SFPs, refer to the most recent version of the
ExtremeXOS release notes.
SX SFP Module
The SX SFP module provides a 1000BASE-T optical connection using LC connectors and multimode
fiber cable up to 300 meters long. The SX SFP module conforms to the 1000BASE-SX standard.
SX SFP modules are supported in the following Extreme Networks switches:
● BlackDiamond 10808
● BlackDiamond 8800 series
● BlackDiamond 12800 series
● Summit X150 series
● Summit X250e series
● Summit X450 series
● Summit X450a series

Optical Budget Calculation
When you plan an installation using the SX SFP module, Extreme Networks recommends that 3 dB of
the total budget be reserved for losses induced by cable splices or connectors and operating margin.
There is no minimum attenuation or minimum cable length restriction.
LX SFP Module
The LX SFP module provides a 1000BASE-T optical connection using LC connectors and single-mode
fiber (SMF) cable up to 10 km long. The LX SFP module conforms to the 1000BASE-LX standard.
LX SFP modules are supported on the following Extreme Networks switches:
● BlackDiamond 10808
● BlackDiamond 8800 series
● BlackDiamond 12800 series
● Summit X150 series
● Summit X250e series
● Summit X450 series
● Summit X450a series
