300km is going to require amplifiers at intervals across the span. Who is=20
providing the fiber? I'd start talking to traditional transport vendors. =20
Ekinops as mentioned is probably decent at a lower price, Adva works well=20
and isn't all that expensive, even Cisco has gear reasonably priced. If=20
you want to cover 300km on a fiber span though "cheap" isn't really a word=20
I would describe. It's why people lease circuits. :)=20
