These guys are pretty inexpensive. Take it for what it is :)

We have several buildings and a couple data centers spread around 
the
city and interconnected via dark fiber. It's a very simple setup - no 
ROADM, no real ring, no extended layer-2 or layer-3 via the optical gear.


Pretty much we just mux/demux a channel for each building so that 
each
building sees the two data centers directly even though the fiber span 
may wind through a couple buildings along the way. In some cases, the 
distance is short enough to use colored optics in the network gear, 
but mostly the distances are just long enough to warrant transponder cards.


All that being said, a lot of the gear is approaching end of life
(support in some cases). I'm not an optical guru but I can muddle my 
way through with Cisco ONS and I'm aware that Ciena and Fujitsu also 
have similar products. We really don't have budget for a large optical 
refresh effort. However, we've saved some money here and there in the 
routing/switching arena by leveraging Arista and even Cumulus. I'm 
wondering if there are smaller players in the optical arena that have 
a good quality/price value?


Again, we don't need sophisticated features... we primarily have 
2-to-4
1Gb and 10Gb ports required per site, then we mux those onto a 
wavelength and extend it to the two data centers. Most buildings are 
set up the same way, each on a different wavelength so the don't even see each other...
only the data centers.


If you guys know of any optical gear that you can vouch for (and 
which
costs less than a small house), we would greatly appreciate it. Thanks
