Let me clarify a bit-I understand that 40GBase-LR4 uses 4 10g wavelengths(lanes) which typically are: 1264.5- 1277.5 nm 1284.5–1297.5 nm 1304.5–1317.5 nm 1324.5–1337.5 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?

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. Regards, Mitchell T.
