euNetworks Further Expands Hollowcore Fiber Footprint

January 13th, 2023 by · Leave a Comment

We don’t hear as much about the ultra-low latency fiber infrastructure favored by high-frequency traders these days, perhaps because there’s not as much new going on. But euNetworks has found an interesting angle in the form of hollowcore fiber and this morning they deployed more of it over in the London metro area.

euNetworks’ infrastructure spans most of western Europe, but in this case we are talking about very specific routes in the London metro area. The new deployment adds 26km of hollowcore fiber between the London Stock Exchange and Basildon to the east. Combined with earlier deployments, that gives them a 40km route with no mid-span amplification.

euNetworks first started deploying hollowcore in April of 2021 with just 1km of the stuff connecting the LSE to a nearby Interxion facility, and followed up a year later with another 7km. Then it was a hybrid route to Basildon six months later. Now that route is 100% hollowcore. Clearly they have been taking pains to get it right, but the trend is clear.

The company says it will be looking at more routes, not just in the metro but in the longhaul. There are likely more London routes in the drawing board, but I’ll bet the broader Frankfurt/London/Amsterdam/Paris routes are on there too. Within hollowcore fiber signals travel some 50% faster than in normal fiber, rivaling the speed of the wireless systems that have dominated this space for over a decade but of course with much greater capacity.
