Re: Low to Mid Range DWDM Platforms

[Collin Rose <collinr () gmail com>]

Sorry for the late response, but I can speak about the FS M6200 product. We have been using the 10GOEO card for 10G 
DWDM/WDM on a span. The hardware works reasonably well though we had to reseat a card once in the last 18 months or so 
of operation. It also seems to be a bit finicky when you first install a new card. Their support had us slot/reslot and 
move around a few times before things started working as expected. My biggest complaint is that the ONLY way to manage 
the box is through the EMS system, which must be installed on a windows OS. It has an embedded apache server that 
provides the interface, so it doesn’t have to run on windows server. The EMS uses SNMP for all the configuration of the 
hardware itself. We figured out how to do some basic things like change the IP using snmp, but besides, that there is 
no way to manage it without connectivity back to the EMS, no CLI, no internal web interface, etc.

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<http://fs.com>?

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.
