Tunable QSFP Optics

No, though the lane colors are irrelevant since we only care about the final output color. Why the lanes can’t be muxed into another output color I’m not sure, I can only find specs listed for the lanes but nothing for the final mux leaving the transceiver.

So you weren't able to find anyone that uses different lane colors?(As an example 1550). I am not looking to mux alongside 10g waves, I am just looking to put 3 or 4 on a single fiber pair.

They still leave the transceiver as a single 1310, the lanes color isn't ever expose since the mux takes place within the transceiver. When I looked into this for 40g and 100g I found no way to passively do it.

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?

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.
