Tunable QSFP Optics

Thu Jun 21 03:32:44 UTC 2018

This little bad-boy has the wavelengths (I believe all exactly 1310.00nm) broken out onto individual fibers (MTP/MPO) 

https://www.fs.com/products/37016.html

Combine with: https://www.fs.com/products/30515.html and 4 DWDM SFP+ modules, plus 4 standard 10G LR SFP+.

Receiver sensitivity kind of sucks, but regen/amps should make interesting deployments possible with standard gear.

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.
