Virgin Media tests Infinera XR optics - coherent optical subcarrier aggregation

Virgin Media has trialed prototype Infinera XR optics technology in its network in Reading, UK to send and receive data at up to 400Gbps in a single fiber.

In 2019, Virgin Media trialed 10Gbps symmetric full fiber home broadband technology in Papworth, Cambridgeshire. 

Infinera said 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.


In the trial, the traditional network transceivers were replaced with Infinera XR optics technology, splitting a single fiber optic cable into many connections.

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.

“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.”

Infinera announces XR optics partnerships with II-IV and Lumentum

Infinera announced a collaboration with II-VI, a global leader in optical communications modules, to bring to market XR optics-based networking solutions. The companies said the partnership will result in the introduction of a family of easily deployable, pluggable XR optics offerings applicable across a wide variety of market applications.

Infinera said XR optics enables radically more efficient and cost-effective solutions for the transport networking challenges operators face in delivering new 5G, enhanced broadband, and cloud-based business services. Infinera's XR optics technology, which is optimized for hub-and-spoke traffic patterns, is powered by independently routable Nyquist subcarriers and coherent optical aggregation capabilities. XR optics technology enables a single high-speed transceiver to simultaneously send and receive independent data streams to/from numerous low-speed transceivers.

In addition, Infinera announced a separate partnership with Lumentum to bring to market XR optics-based networking solutions. The partnership will result in the introduction of a family of easily deployable, pluggable XR optics offerings applicable across a wide variety of market applications.


Infinera's XR Optics delivers coherent optical subcarrier aggregation

Infinera introduced a point-to-multipoint coherent optical subcarrier aggregation technology with the potential to significantly reduce the number of transceivers required in an access network while eliminating intermediate aggregation.

Infinera's XR optics technology, which is optimized for hub-and-spoke traffic patterns, is powered by independently routable Nyquist subcarriers and coherent optical aggregation capabilities. With coherent subcarrier aggregation (CSA) capabilities, XR optics technology enables a single high-speed transceiver to simultaneously send and receive independent data streams to/from numerous low-speed transceivers.
Subcarriers can be flexibly sized. For example, 4 X 25G subcarriers defined in a 100G QSFP-28 transcrivers; or 16 X 25G subcarriers defined in a 400G QSFP-DD transceiver.

The company says that by leveraging these capabilities, network operators will be positioned to significantly reduce the number of transceivers in the network, eliminate the need for costly intermediate aggregation devices, and more efficiently optimize transport infrastructure for hub-and-spoke end-user traffic flows.

Initial areas of focus include DAA fiber deep networks, 5G X-haul, DSL/PON backhaul, and fiber-enabled business services.

XR optics is designed to be integrated into a variety of form factors, including industry-standard pluggables, from low-speed interfaces with a single subcarrier to high-speed (400G+) interfaces with numerous subcarriers.

Liberty's Virgin Media to merge with Telefónica's O2

Liberty Global plc and Telefónica SA will merge their operating businesses in the U.K. to form a 50:50 joint venture focused on broadband + mobile + video + entertainment consumer services. O2 is the largest mobile platform in the UK, while Virgin Media claims to be the nation's fastest broadband network.

The "fully-converged" JV is also expected to become a leading challenger in the B2B space as the combination will accelerate the adoption of converged fixed-mobile services to Virgin Media’s and O2’s existing business customers.

The JV will have an approximate annual turnover of £11 billion, and 46 million mobile, home, and business connections.

The companies cite significant operating benefits for the JV, with estimated run-rate cost, CAPEX and revenue synergies of £540 million on an annual basis by the fifth full year post closing, equivalent to a net present value of approximately £6.2 billion post tax and net of integration costs, as well as significant synergies from the accelerated usage of existing tax assets. The vast majority of the benefits relate to demonstrable cost and CAPEX synergies, with an annual run-rate of approximately £430 million out of which approximately 80% are expected to be achieved by the third full year after the closing.

CAPEX synergies:

  • Use of existing infrastructure to provide services for each entity’s customers at lower cost compared to standalone / wholesale capabilities;
  • Migration of Virgin Media mobile traffic to Telefonica UK’s network;
  • Combination of regional and national network infrastructures and IT systems;
  • Reduction in combined marketing expenditures;
  • Potential to reduce general and administration costs; and 
  • Site rationalization

Telefónica's Chief Executive Officer, Jose Maria Alvarez-Pallete, said, “Combining O2’s number one mobile business with Virgin Media’s superfast broadband network and entertainment services will be a game-changer in the U.K., at a time when demand for connectivity has never been greater or more critical. We are creating a strong competitor with significant scale and financial strength to invest in UK digital infrastructure and give millions of consumer, business and public sector customers more choice and value.  This is a proud and exciting moment for our organisations, as we create a leading integrated communications provider in the U.K.”

Mike Fries, Chief Executive Officer of Liberty Global, said, “We couldn’t be more excited about this combination. Virgin Media has redefined broadband and entertainment in the U.K. with lightning fast speeds and the most innovative video platform. And O2 is widely recognized as the most reliable and admired mobile operator in the U.K., always putting the customer first. With Virgin Media and O2 together, the future of convergence is here today. We’ve seen the benefit of FMC first-hand in Belgium and the Netherlands. When the power of 5G meets 1 gig broadband, U.K. consumers and businesses will never look back. We’re committed to this market and are right behind the Government’s digital and connectivity goals.”
