Re: Tunable QSFP Optics

["Lewis,Mitchell T." <ml-nanog () techcompute net>]

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?

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.
