Let me clarify a bit-I understand that 40GBase-LR4 uses 4 10g wavelengths(lanes) which typically are:
1264.5- 1277.5 nm
1284.5â??1297.5 nm
1304.5â??1317.5 nm
1324.5â??1337.5 nm
My question is are there any vendors that make optics which 4 wavelengths(lanes) are something other than those typically used by 40GBase-LR4?

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.
