euNetworks Digs Deeper Into Hollowcore

Following up on its initial deployments of hollowcore fiber in London over the last year and a half, euNetworks has announced the deployment of a new route out to Basildon. The new 45km route is a hybrid of hollowcore and regular single mode fiber, cutting 10% off the latency on the route.

The company first started doing this in April 2021 on a 1km route between the London Stock Exchange and an Interxion facility, and this past March added another 7km to Interxion’s LON1 facility. The new hybrid route contains 14km of hollowcore fiber.

The speed of light in hollowcore fiber is 50% greater because it’s moving in air and not glass. That gives it a 3µs per kilometer advantage, which means a lot to latency-critical industries such as high speed trading. So far euNetworks has found economically viable ways to leverage this in the London metro area, but there’s no reason they can’t do the same thing in, around, and between other financial markets.
