Re: 100G over 100 km of dark fiber

hey,

I need to push 100G over 100 km of dark fiber. Since there are no 100G pluggable optics with this reach (~25 dB), I 
have been offered coherent transport systems to solve my problem. This is all good and well, except total system costs 
start from high five figures.

100G-ZR4 QSFP28 is on the market and works. Just watch out for power limitations, your typical DC switch might not support it but proper stuff has no problems providing 6.5W of power.
