What optical wavelength is used by Cisco modules (850 vs. 1300)?

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.

    your card is using 100base-fx standard so it uses 1300 nm wavelength
