Openreach demonstrates world's first 100Gbps broadband connection

Tuesday, June 13th 2017 by Phil Wilkinson-Jones

Openreach has demonstrated the world’s first 100Gbps broadband service at its Adastral Park research centre in Suffolk.

The demonstration uses advanced transmission technology to deliver faster speeds over a standard residential fibre to the premises (FTTP) connection.

Developed alongside Huawei, the new technology would give users enough capacity to stream 4,000 ultra HD movies simultaneously.

Mark Lam, Openreach’s chief information officer, said: “It demonstrates a massive hike in speed – the highest we’ve seen worldwide.

“In fact it’s so fast that it’s actually very hard to transmit anything over it that can properly illustrate the capacity.

“It would pump more bandwidth into your home than the TV broadcasters use to transmit their raw footage from a football match.”

Mr Lam said growing bandwidth requirements and the impending introduction of 5G mobile networks show the need to stay ahead of demand.

“Bandwidth requirements are increasing at a rate of around 40 per cent year on year, as services such as ultra-high definition video grow rapidly.

“There are predictions now that it would take more than five million years to watch just the amount of video that will cross global networks each month in 2020.”

Upgrading cabinets to G.Fast

As part of BT’s Innovation Week event, Openreach also demonstrated extensions to its broadband cabinets that will allow it to roll out ultrafast speeds using G.Fast technology.

The company has developed G.Fast ‘side pods’ that can be bolted on to existing copper cabinets in locations where there is also a superfast fibre cabinet.

Trevor Linney, head of access network research at BT, said homes within 400 metres of an upgraded cabinet would be able to access speeds of more than 100Mbps.

“G.Fast is something we’ve been working on for a number of years, but the key difference today is its deployment.

“We’ve gone on a journey where we used to aim for G.Fast to operate on gigabits over tens of metres into something that delivers hundreds of megabits over hundreds of metres.

“It can use all the great investment Openreach has made already made in its infrastructure to reach as many customers as possible.”
