Hi jared as others have pointed out there are lots of options inphi offers these https://www.inphi.com/products/colorz/ or use a box like packetlight, here is a Arista solution brief https://www.arista.com/assets/data/pdf/Whitepapers/Arista_Packetlight_100G_Extension_Solution.pdf and if you serch for openline systems there are a few that do smaller systems 2/4/8 ports that are available FS even offers this https://www.fs.com/de-en/specials/100g-fmx-transport-platform-103.html more expensive than optics but an alternative and you can stay in low 5 figures. cisco has the ncs55a2 with these https://www.cisco.com/c/en/us/products/collateral/routers/network-convergence-system-5500-series/datasheet-c78-743732.html that costs like a gazzilion dollars but your company may have great discounts...

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. So, my question is, do I have any other options? I can't help noticing that you can break out a 100G QSFP into four 25G QSFPs. 25G DWDM systems are relatively inexpensive (low five figures), but can you make 25G DWDM go 100 km? I only need the one 100G, so I don't really need a highly scalable DWDM system. I can't put anything midspan, or if I could it would cost more than just going with a coherent system. Jared
