1 Gb LX and Industrial Grade LX SFP Modules

Part numbers: I-MGBIC-GLX, AA1419049-E6, 10052H (Industrial Grade), 10072H (Industrial Grade, 10-pack)

The LX and Industrial Grade LX SFP modules provide a 1000BASE-X optical connection using LC connectors and SMF (single-mode fiber) cable up to 10 km long.

For a complete listing of hardware compatible with these modules, see the Extreme Optics Compatibility website.

Transmission distances are provided as a nominal guide only. To determine achievable distances, refer to the device's optical specifications and to the specific characteristics of your fiber installation.

Optical Budget Calculation

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. There is no minimum system budget or minimum cable length restriction because the maximum receive power is the same as the maximum transmit power. There is no minimum attenuation or minimum cable length restriction.

LX SFP Specifications

The LX and Industrial Grade LX SFPs conform to the 1000BASE-LX standard.

The LX SFP modules operate at a commercial temperature range (0°C to 70°C). The Industrial Grade LX SFP module operates at a wide temperature range (-40°C to 85°C).

The following table lists specifications for the LX and Industrial Grade LX SFP modules. The specifications listed are for parts I-MGBIC-GLX and 10052H. Specifications for other parts are substantially similar but might not be identical.
