I wonder if I want connect two CRS-4 over 110Km lenght and get 40G of througput whitout ONS 15454 MSTP DWDM infrastructure.
I am looking for lowering the cost for a two cities point-to-point carrier class connection with high throughput.
In DWDM platform it can go 1000Km without 3R regeneration means the signal still have to go through OPtical Amplifier & Dispersion modules but it does not any transponder to retime the signal(in simple words you are not converting from optical to electrical anywhere in 1000Km link).
Throughput will be 40G in both cases for single wavelngth/channel. Do you mean something else by throughput.
