Comcast deploys its first hollow-core fiber in the US

Comcast announced it is adopting advanced hollowcore fiber to serve as the foundation for its faster 10G network which will be capable of 10 gigabits per second internet speeds. In a test of the technology, Comcast connected two Philadelphia locations with 40-kilometer hybrid deployment of hollowcore and traditional fiber. It is believed to be the longest such networking in the world.

Just as the name suggests, hollow core fiber cables have an air-filled central channel surrounded by a ring of glass strands such that a cross section looks rather like honeycomb with an empty hole in the middle. The idea behind this arrangement is that light travels 50% faster through air than over glass, meaning such cabling can deliver better performance and lower latency.

Comcast is the first internet service provider to adopt the fiber optic cable, which delivers faster internet speeds and lower latency (network response). This real world deployment is a significant boost to Comcast's network and will help it bring about 10G networking. For the deployment announced today, Comcast worked with hollowcore fiber cable solutions provider, Lumenisity.

"Hollowcore fiber is a leap forward in how we deliver ultra-fast, ultra-low latency and ultra-reliable services to customers," said Elad Nafshi, EVP & Chief Network Officer at Comcast Cable. "As we continue to develop and deploy technology to deliver 10G, multigigabit performance to tens of millions of homes, hollowcore fiber will help to ensure that the network powering those experiences is among the most advanced and highest performing in the world."
