--- Hello NANOG! 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

Hi Jared, Easiest thing would be breaking into sub-100G channels (e.g. 4x 25G) and using DWDM optics + Amp + Compensation + Pre-Amp to transport it across the 100km. Same parts for all configs: *) 1x Amplifier => 1 slot *) 1x 100km dispersion compensation => separate 1U *) 1x Pre-Amplifier => 1 s

hey, If it’s just a single 100G channel needed you could try 100GBASE-ZR4. Specified for 80km, 30db power budget they could actually reach more the 80km. Dispersion should also be „no" problem in the 1310nm length. I have to say that I never tried this on 100km distance without coherent soluti
