Virgin Media Trials Infinera’s Cutting Edge Multi-gigabit Network Technology

Infinera announced that Virgin Media has trialed innovative network technology which provides new ways to roll out multi-gigabit speeds to consumers and businesses.

The trial, delivered on the operator’s network in Reading, UK, saw Virgin Media install prototype Infinera XR optics technology in its network. The new equipment plugs into the existing network and can send and receive data at much higher speeds than was previously possible – reaching transfer rates of up to 400Gbps in a single fiber.

In 2019, Virgin Media trialed 10Gbps symmetric full fiber home broadband technology in Papworth, Cambridgeshire. This new trial goes a step beyond that, demonstrating that the operator’s passive fiber optic access network (PON) – which provides multiple premises with full fiber connections – could deliver 400Gbps symmetrical services by making use of the latest technology.

Fiber optic networks transmit data from one point to another through a series of electrical switches and optical transceivers. These optical transceivers control where the information is sent and at what speed, ultimately determining how fast data can be sent from one point to another.

In the trial, the traditional network transceivers were replaced with cutting-edge technology which split a single fiber optic cable into many connections, all taking a share of the huge capacity. This means a single fiber could be used to provide multi-gigabit speeds to many customers at the same time.

By using standard passive optical network technology, the transceivers can support higher speed data transfers and can be remotely upgraded and configured. This allows the network operator to make changes quickly and easily, paving the way for simple upgrades to consumer services in future.

This new technology could help support the rapidly growing demand for data which is being driven by high-quality video streaming, remote working, and immersive entertainment, as well as the need to carry 5G traffic to and from mobile phone masts as well as other emerging bandwidth intensive technologies.

Jeanie York, Chief Technology and Information Officer, Virgin Media, said: “Our next-generation network already offers gigabit connectivity to more than 7 million homes, but with data use and demand for hyperfast speeds surging, we’re continually investing in our network to prepare for whatever the future brings.

“Innovations like XR optics ensure our customers continue to benefit from the UK’s fastest widely available speeds, pave the way for future network upgrades and help support the rollout of multi-gigabit broadband and mobile services.”

“The trial with Virgin Media provides a solid proof point that Infinera’s XR optics technology can be seamlessly applied to existing networks,” said Dave Welch, Infinera Chief Innovation Officer and Co-founder. “This represents a radical shift in the way networks can be built, promising a more flexible and sustainable way to meet the ever increasing need to transmit more data at higher speeds.”
