Many thanks to all to who have responded. We're reviewing some of our infrastructure over the summer, which I why I wanted to be up to speed on the current states of the market, and I may take-up the kind offers of vendor contacts then.
Briefly, in answer to the questions below: at the time we first deployed this, the cost differential between CWDM and DWDM was significant enough to make a difference, in conjunction with the other factors; CWDM, being passive, simplified some of the availability issues we had to deal with the fibre topology we then had; and finally, it also eliminated some "scoping" issues that we might have had with active equipment and stuff like PCI (device management, etc.) Thanks again. -- David From: Ed Butler [mailto:[email protected]] Sent: 12 June 2013 14:57 Cc: [email protected] Subject: Re: [uknof] CWDM kit...

We used Nortel last time, which have been fine, but now that they are no more, I was wondering what else the list might recommend? Probably not the answer you're looking for, but any reason you're not using DWDM? We find the cost differences are so small it's more than worth the step to DWDM for the flexibility it gives you. We have very short lengths of fibre (<1km) that are lit with DWDM for this reason.
