850 vs 1300nm wavelength

[frank_nye]

I am trying to verify what wavelength our Cisco cards operate at. The cards in question are WS-X4148-FX-MT cards that we have in our Catalyst 4006 switch.

I imagine they operate at a wavelength of 1300 nm (vice 850) but I need to verify so I can detemine if we have the correct media converters.

I looked up the specs for the card on the Cisco web site but no mention is made of the wavelength.

Thanks for any information you can provide.

100BASE-FX outlines 1300nm MMF, which is what is outlined in this module's specification.

The 100BASE-SX outlines 850nm MMF.

It would be nice if they included this within the documentation.
