I've set a few people up with FS.com, and my $employer uses then for a lot of DWDM without issue.
as another fs.com user of cwdm muxes... yes, in the limited sample I have they work for me... you ought to be able to pair the CWDM muxes like: http://www.fs.com/products/42972.html with their 80km optics and get pretty far along... a 'city' solution shouldn't really need more than 80k, right? :)
Quality bites everyone, cleaning terminations is one of the neglected steps :p On Thu, Nov 2, 2017 at 2:36 PM, Micah Croff <micahcroff () gmail com> wrote:I've used Adva passive DWDM MUX's and colored FlexOptix DWDM 10G optics.Itworked very well with zero issues. I haven't personally used MUX's from fs.com but I've had colleagues use them and caution against them due to the quality.

We have several buildings and a couple data centers spread around thecityand interconnected via dark fiber. It's a very simple setup - no ROADM,noreal 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 spanmaywind through a couple buildings along the way. In some cases, thedistanceis short enough to use colored optics in the network gear, but mostlythedistances are just long enough to warrant transponder cards. All that being said, a lot of the gear is approaching end of life(supportin 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 refresheffort.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/pricevalue?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 awavelengthand extend it to the two data centers. Most buildings are set up thesameway, 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 LFOD-- Brent Jones brent () brentrjones com
