I'm in the process of researching DWDM equipment for a new ring I'm about to light. Only two dark fibers to start. My only experience with WDM is a ring lit with MRV CWDM equipment by another provider. The MRV equipment hasn't failed once in the years I've had the service. Good/bad/ugly thoughts on MRV? What I'm looking for is the ability to drop 10G and 1G channels on the same ring. Upgradability to 40G channels is a plus. I haven't been told I should plan for OC-n but it would nice if I had the option. Does anyone have a recommendation that might fit these requirements? Thanks

I've used the MRV Lambdadrivers for a ring using DWDM, 16 channel MUX/DEMUX, with one channel using an 8-in-1 10G TDM device (tunable). No complaints here apart from the need to use MU connectors. M

MU gives slightly lower attenuation than other types of physical connector (i.e. non spliced). It's a minor pain if you don't have an easy source of MU patch cables, but there are sound reasons for using it. I use Transmode kit, and have found it to be very reliable. Would have no problem recommending it to others. Nick
Hello, We moved from MRV to Ekinops (http://www.ekinops.net/). Mrv was really stable ( no issue for the last 3 years), but they are slow in innovation. The new cards just came out. For a simple and cheap solution, I will benchmark, Mrv, Ekinops and BTI. The most innovative and with easy R&D access is Ekinops ( we got special version of a code for a card) You can also contact Transmode but they are slow in response and we clearly don't understand their strategy with multiples card and multiples series. I worked with a customer using transmode, for a simple ring solution, he have 4 type of connectors !!! :) -- Raphaël Maunier NEO TELECOMS CTO / Responsable Ingénierie AS8218 On May 22, 2010, at 5:52 PM, ML wrote:
I've been pretty happy with the Adva FSP3000R7 units. Lots of options for 1g and 10g and they are very helpful with setup and design. There's a lot more to it than just coming up with an attenuation budget. --chip On Sat, May 22, 2010 at 11:52 AM, ML <ml@kenweb.org> wrote:
