Low to Mid Range DWDM Platforms

Fri Oct 6 14:17:44 UTC 2023

Well, and that's kinda where I was going. 

I've used FS passive systems for years. FS has an active platform or two (that I understand, they just whitebox). Does it really do everyone one would need to do? How much of a step is it to get something more?

On the same topic, anyone have experience with the stuff from fs.com ?

I know of multiple vendors in that space, but I like to learn more about what features I need and what features I don't need from somewhere other than the vendor's mouth. Obviously, the most reliability at the least cost as well. 

400G-ZR pluggables will get you 400Gbps on a p2p dark fibre over 80km - 
100km. So your main cost there will be routers that will support. 

The smallest DCI solution from the leading DWDM vendors is likely to be 
your cheapest option. Alternatively, if you are willing to look at the 
open market, you can find gear based on older CMOS (40nm, for example), 
which will now be EoL for any large scale optical network, but cost next 
to nothing for a start-up with considerable capacity value. 

There is a DWDM vendor that showed up on the scene back in 2008 or 
thereabouts. They were selling a very cheap, 1U box that had a different 
approach to DWDM from other vendors at the time. I, for the life of me, 
cannot remember their name - but I do know that Randy introduced them to 
me back then. Maybe he can remember :-). Not sure if they are still in 
business.
