A few years ago, NANOG had a discussion regarding various CWDM vendors. Repeatedly MRV was brought up as a good option for metro-area LAN type applications. Since then, I have actually touched some of the MRV product line personally and found it (and their customer support)... less than ideal. (not comparing to anyone else, and no one is really ideal). The bigger problem was that the devices seem to be less than intuitive, but rock solid once they are working. (which is what everyone praised them for). We need to place a new order for some new fiber builds and were considering some other vendors. Especially in the nx2.5G and nx10G (are CWDM x-cievers even available in 10G yet?) range. Anyone have any new favorites? I'll be glad to summarize/commiserate. :) Thanks in advance, DJ
