Low cost WDM gear

Sat Feb 7 19:17:48 UTC 2015

Is this for 10G?  I'm kind of assuming 10G. What kind of equipment is 
being plugged into these?  300km is way beyond what you'll get with a 
passive solution, it's definitely in the "long-haul" terrtory.  If you are 
launching out of a router the best pluggable optic you can generally get 
is rated at 80km, 10GBase-ZR, but even a passive mux at each end shaves 
some of that distance off. 

300km is going to require amplifiers at intervals across the span. Who is 
providing the fiber?  I'd start talking to traditional transport vendors.  
Ekinops as mentioned is probably decent at a lower price, Adva works well 
and isn't all that expensive, even Cisco has gear reasonably priced.  If 
you want to cover 300km on a fiber span though "cheap" isn't really a word 
I would describe.  It's why people lease circuits. :)
