100G over 100 km of dark fiber

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 start from high five figures. So, my question

You could break this into 10x 10g coherent lanes, but you’re going to end up back close to coherent 100g prices. You’re at the threshold distance where you’re past all the short range tech and are seriously pushing it - whereas the 100g coherent tech is just taking off. How important is this

YMMV, but my take: 1 - You should worry a little, but not much. Filters allowing unwanted announcements might be created using these erroneous IRR records, but they won't do any damage by themselves. An actual wrong BGP announcement is required for any damage to happen, and even without those IRR r
