Hi Mike, You should try CYAN inc and the Z series. (US based) Very solid platform and very strong warranty.

You can do ~500km without inline amplifier sites using EDFA+Raman+ROPA, but you are going to need some serious optical engineering to make that work. The more standard way to do it is amplifier sites every 80-100km for EDFA. If you are doing 10GigE you will need to allow for DCM also.

One particular route I'm looking at is 185 miles, so of the options presented 300 km is closest. ;-)

would be good for mike to define 'long distances' here, is it: 2km 30km 300km 3000km
Probably the 30-60k range is what you mean by 'long distances' but... clarity might help.

Mike,
I just replaced a bunch of FiberStore WDM passive muxes with OSI Hardware equipment. The FiberStore gear was a huge disappointment (excessive loss, poor technical support, refusal to issue refund without threatening legal action, etc.). I have had good results from the OSI equipment so far. I run passive muxes for CWDM (8 - 16 channels).

Hi Mike
I can recommend a couple of vendors that provide cost effective solutions. Ekinops & Packetlight.

I know there are various Asian vendors for low cost (less than $500) muxes to throw 16 or however many colors onto a strand. However, they don't work so well when you don't control the optics used on both sides (therefore must use standard wavelengths), obviously only do a handful of channels and have a distance limitation. What solutions are out there that don't cost an arm and a leg? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com
