Extreme Networks SFP and SFP+ Modules

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 switches

BlackDiamond 12800 series switches

BlackDiamond 20800 series switches

Summit X440 series switches

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)

E4G series routers (Ethernet 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.

When in SMF operation, 100FX-SMF or 1000LX, measure cable plant losses with a 1310 nm light source and verify this to be within budget. When you calculate the maximum distance attainable using optical cable with a specified loss per kilometer (for example 0.25 dB/km), Extreme Networks recommends that 3 dB of the total budget be reserved for losses induced by cable splices or connectors and operating margin.

Note

The 100FX/1000LX SFP module detects link status based only on the presence of light in the receive cable. Therefore, if a single strand is broken, the link partner on the other port will not detect link down.

For technical specifications for the 100FX/1000LX SFP, see Technical Specifications.

LX100 SFP Module

The LX100 SFP module provides a 1000BASE-X optical link up to 100km long using LC connectors and SMF cable.

The LX-100 SFP modules are supported on the following Extreme Networks devices:
