The pluggable optic must be DWDM 1530 to 1563 nm with QPSK modulation that fits 50Ghz (~31 to 35Gbaud) and a launch power of ZR+ 0dBm. The customer channel should have Rx: Max <-10 dBm/Ch and Tx: Min: >–5 dBm/Ch to Max: <+ 6.5dBm/Ch in order to meet the GOSNR margin of 2.5dBm or more.
right, so DWDM alien wave requirement then. That's very non-portable and kit specific.
Depending on the application, you might be better off ditching the requirements that they're imposing and simply using 100G transponders (i.e. 100G as a service). Or something like the smartoptics open line system with PAM4 QSFP28 transceivers.
It really depends on what's between you and the other end. D/F has simple options open for single 100G. If you're connecting into something more complicated, it can get messy and expensive.
