Tunable QSFP Optics

I believe the 40g and 100g optics are already muxing 4 channels within the transceiver before outputting it to 1310.

Subject: Tunable QSFP Optics

Does anyone know if any Single Mode QSFPs exist on the market that use wavelengths other than 1310nm (either self tunable or factory tuned)? I am looking to put more than one 40gb link on a fiber pair similar to using DWDM OADMs for 1g & 10g but can't seem to find any qsfp optics that don't use 1310nm.

Thanks.
