CLS to CLS Latency info

The speed of light through fiber is about 2/3 the speed of light through a vacuum. This is why HFT prefers microwave over fiber when it comes to latency.

I’d be astonished if they varied much from lightspeed.

Hello there 

I have been searching for CLS (Cable Landing Station) to CLS latency infirnation for submarine cables. I was able to identify only a handful of them via sales catalogs. I am still missing like 320~ systems, does wnyone have this info available? 

If i can’t find the data, i am going to formulate from lentgh of fiber diveded by speed of light on fibre (~ +\- resistance) but I really would prefer actual ping ;) 

This is for www.networkatlas.org project. Thank you in advance!
