Verizon cites week-over-week rise in traffic

Verizon reported the following week-over-week comparisons of peak hour usage traffic over its residential fiber and wireless consumer networks:

  • Gaming, up 75%
  • VPN, up 34%
  • Web traffic up close to 20%
  • Video, up more than 12%
  • Social media usage: 0%, flat

Verizon said usage is expected to fluctuate over time, especially as more people telecommute and more students are at home.

“As we see more and more individuals work from home and students engage in online learning, it is a natural byproduct that we would see an increase in web traffic and access to VPN.  And as more entertainment options are cancelled in communities across the US, an increase in video traffic and online gaming is not surprising,” said Kyle Malady, Chief Technology Officer for Verizon.  “We expect these peak hour percentages to fluctuate, so our engineers are continuing to closely monitor network usage patterns 24x7 and stand ready to adjust resources as changing demands arise.”

“We’re in an unprecedented situation,” said Malady. “We continually evaluate peak data usage times and build our networks to stay ahead of that demand.  “While it is not clear yet how having millions of additional people working from home will impact usage patterns, we remain ready to address changes in demand, if needed.”

Infinera carries 800G wavelength at 96 Gbaud over 950km

Infinera completed a live network trial of 800G single-wavelength transmission at 96 Gbaud over 950 kilometers (km) across a long-haul link in a major North American network operator’s production network.

The production network trial, which was conducted over a third-party optical line system carrying live multi-vendor traffic, leveraged Infinera’s Groove (GX) Series, equipped with its sixth-generation dual-800G Infinite Capacity Engine (ICE6) technology.  The trial demonstrated Infinera’s vertically integrated ICE6 optical engine, which features second-generation Nyquist subcarriers, 64QAM with per-subcarrier long-codeword probabilistic constellation shaping, and per-subcarrier dynamic bandwidth allocation. The operator's network used G.652 fiber.

Infinera said the achievement signals a major industry milestone in driving down the cost per bit of telecommunications networks.

“The success of this trial proves our ability to transmit 800G high-baud-rate signals across significant distances, which will be instrumental in driving down network costs,” said Parthi Kandappan, Chief Technology Officer at Infinera. “This marks another major accomplishment for Infinera’s Optical Innovation Center, adding to its long history of pioneering innovations in optical networking.”

Infinera and Corning carry 800G wavelength over 800km

Infinera has demonstrated the ability to carry an 800 Gbps wavelength across 800km on Corning’s TXF optical fiber.

The achievement leveraged Infinera’s sixth-generation Infinite Capacity Engine (ICE6) technology in a Groove (GX) Series platform transmitting 800G using 64QAM with probabilistic constellation shaping (PCS). ICE6 combines Infinera’s sixth-generation photonic integrated circuit with its in-house-developed 7-nanometer dual-channel 800G per-wave FlexCoherent digital signal processor.

Corning’s state-of-the-art TXF fiber is an ITU-T G.654.E compliant, ultra-low-loss, silica-core fiber with large effective area.

The companies said the success of the 800G trial highlighted the advanced features of Infinera’s vertically integrated ICE6 technology, including Nyquist subcarriers, per-subcarrier long-codeword PCS, and per-subcarrier dynamic bandwidth allocation, along with superior fiber designed to help meet growing bandwidth demands for network operators from metro to subsea network applications.

NeoPhotonics intros 64 GBaud L-band coherent optical components

NeoPhotonics introduced an L-Band suite of coherent optical components, including its 64 GBaud L-Band High Bandwidth Coherent Driver Modulator (HB-CDM), 64 GBaud L-Band Intradyne Coherent Receiver (ICR) and ultra-narrow linewidth L-Band tunable laser Micro-ITLA. NeoPhotonics already supplies standard C-Band coherent components.

NeoPhotonics notes that the L-Band uses wavelengths centered around 1590 nm and is primarily used to complement the C-Band (1550 nm) to increase data capacity, especially in long-haul networks. By adding channels in the L-Band, operators can double the capacity of an optical fiber. NeoPhotonics 64 Gbaud coherent components and tunable lasers enable single channel 600G data transmission over short haul data center interconnect (DCI) links using 64 QAM. These components also support 400G over metro distances of 400-600 km using 64 GBaud and 16 QAM or 200G over long-haul distances of greater than 1000 km using 64 GBaud and QPSK.

The NeoPhotonics L-Band External Cavity (ECL) micro-ITLA incorporates the same laser architecture as its C-Band laser for a pure optical signal with an ultra-narrow linewidth and very low phase noise. In coherent systems, any error in the phase of the signal and reference lasers, due to the laser’s linewidth, can cause data errors, thereby making narrow linewidth critical in systems using higher order modulation.

The NeoPhotonics 64 Gbaud L-Band HB-CDM co-packages an Indium Phosphide based Mach-Zehnder (MZ) quadrature modulator chip with a linear, quad-channel, differential 64 GBaud driver. Both the C-Band and L-Band versions of the HB-CDM are designed to be compliant to the Optical Internetworking Forum (OIF) Implementation Agreement OIF-HB-CDM-01.0 “High Bandwidth Coherent Driver Modulator”.

NeoPhotonics 64 Gbaud L-Band Micro-ICR incorporates an integrated comixer chip and four balanced photodiodes with four differential linear amplifiers to provide four output channels at 64 GBaud. The form factor of the High Bandwidth Coherent Receiver is designed to be compliant with the OIF Implementation Agreement for Micro Integrated Intradyne Coherent Receivers; IA # OIF-DPC-MRX-02.0.

For applications that require more capacity than provided by the standard C-Band, but do not require the full L-Band, each of these components is available in a “C++” version, which supports tuning across the full “Super C-band” covering 6.0 THz of spectrum or up to 50 percent more than standard systems. These C++ components can support 80 channels at 75 GHz channel spacing, which effectively increases the capacity of an optical fiber by as much as 50 percent over standard C-Band only systems at comparable distances.

"We are pleased to add L-Band versions to our existing suite of coherent components, thus providing customers with a complete solution to their fiber capacity requirements, whether C-Band, C++ Band or L-Band," said Tim Jenks, Chairman and CEO of NeoPhotonics. "Our ultra-pure tunable laser design and our high performance coherent modulator and receiver designs are very flexible and excel in different spectral regimes to provide the highest speed over distance performance," concluded Mr. Jenks.

Samsung Electronics delivers 512 GB flash storage for smartphones

Samsung Electronics has begun mass producing the first 512-gigabyte (GB) eUFS (embedded Universal Flash Storage) 3.1 for use in flagship smartphones.

The Samsung 512GB eUFS 3.1 offers a sequential write speed of over 1,200MB/s, which is more than twice the speed of a SATA-based PC (540MB/s) and over ten times the speed of a UHS-I microSD card (90MB/s). This means consumers can enjoy the speed of an ultra-slim notebook when storing massive files like 8K videos or several hundred large-size photos in their smartphones, without any buffering. Transferring contents from an old phone to a new device will also require considerably less time. Phones with the new eUFS 3.1 will only take about 1.5 minutes to move 100GB of data whereas UFS 3.0-based phones require more than four minutes.

In terms of random performance, the 512GB eUFS 3.1 processes up to 60 percent faster than the widely used UFS 3.0 version, offering 100,000 input/output operations per second (IOPS) for reads and 70,000 IOPS for writes.

Along with the 512GB option, Samsung will also have 256GB and 128GB capacities available for flagship smartphones that will be launched later this year.

Nokia hits record single carrier bit rate of 1.52 Tbps over 80 km

Researchers at Nokia Bell Labs achieved a world record for the highest single carrier bit rate at 1.52 Terabits per second (Tbps) over 80 km of standard single mode fiber.

Marcus Weldon, Nokia CTO and President of Nokia Bell Labs, said: “It has been fifty years since the inventions of the low-loss fiber and the associated optics. From the original 45 Megabit-per-second systems to more than 1 Terabit-per-second systems of today – a more than 20,000-fold increase in 40 years – to create the fundamental underpinning of the internet and the digital societies as we know it. The role of Nokia Bell Labs has always been to push the envelope and redefine the limits of what’s possible. Our latest world records in optical research are yet another proof point that we are inventing even faster and more robust networks that will underpin the next industrial revolution.”

The Nokia Bell Labs optical research team, which was led by Fred Buchali, employed a new 128 Gigasample/second converter enabling the generation of signals at 128 Gbaud symbol rate and information rates of the individual symbols beyond 6.0 bits/symbol/polarization.  This accomplishment breaks the team’s own record of 1.3 Tbit/s set in September 2019 while supporting Nokia’s record-breaking field trial with Etisalat.

Several of these achievements were presented as part of Nokia Bell Labs’ post deadline research papers at the Optical Fiber Communications Conference & Exhibition (OFC) in San Diego.

Additionally, Nokia Bell Labs researcher Di Che was awarded the OFC Tingye Li Innovation Prize.

Recently, Di Che and team also set a new data-rate world record for directly modulated lasers (DML) by transmitting a 400 Gbps signal up to 15 km.

Nokia Bell Labs also highlighted the following significant achievements in optical communications:

The first field trial using spatial-division-multiplexed (SDM) cable over a 2,000km span of 4-core coupled-core fiber was achieved by researchers Roland Ryf and the SDM team. The experiments clearly show that coupled-core fibers are technically viable, offer high transmission performance, while maintaining an industry standard 125-um cladding diameter.
A research team led by Rene-Jean Essiambre, Roland Ryf and Murali Kodialam introduced a novel new set of modulation formats that provide improved linear and nonlinear transmission performance at submarine distances of 10,000 km. The proposed transmission formats are generated by a neuronal network and can significantly outperform traditional formats (QPSK) used in today’s submarine systems.
Researcher Junho Cho and team experimentally demonstrated capacity gains of 23% for submarine cable systems that operate under electrical supply power constraints. The capacity gains were achieved by optimizing the gain shaping filters using neural networks.
The researchers that achieved the world record and research results are part of Nokia Bell Labs’ Smart Optical Fabric & Devices Research Lab, which designs and builds the future of optical communications systems, pushing the state-of-the-art in physics, materials science, math, software and optics to create new networks that adapt to changing conditions and go far beyond today’s limitations.

Google's Dunant transatlantic cable makes landfall in France

Google’s transatlantic Dunant cable has landed in Saint-Hilaire-de-Riez, in the Vendée region of France. The terrestrial stage of the laying of this cable is proceeding.

As the “Landing Party” and owner of the French part of the cable, Orange has completely refurbished the historic station in Saint-Hilaire-de-Riez, which was no longer in use, to house the terminal equipment for the Dunant system. This area is a strategic location, close to the main connectivity hubs on this side of the Atlantic. From this landing station, Orange is deploying terrestrial optical fibres in France between Saint-Hilaire-de-Riez and Paris to route its traffic on the Dunant cable to the capital's major Data Centres and will also provide service to the rest of Europe and major international Data Centres.

Orange will benefit from two pairs of optical fibres with a capacity of up to 30Tbps each.

"We are very pleased with the arrival of the Dunant cable in France. It is the concrete realization of a project in co-construction with Google that will enable us to respond to the explosion of Internet usage over the long term. This partnership strengthens Orange's role as a world leader in the investment, deployment, maintenance and operation of strategic infrastructures. The landing of Dunant on our shores once again places France at the heart of the global digital development," said Jean-Luc Vuillemin, Senior Vice President, International Networks and Services at Orange.

Orange and Telxius to backhaul Google's Dunant transatlantic cable

Orange and Telxius will provide terrestrial backhaul extensions in France and in the US for Google's Dunant submarine cable, which is expected to enter service in late 2020.

Under this agreement, Orange and Telxius offer co-location services at their respective Cable Landing Stations in Saint-Hilaire-de-Riez (France) and Virginia Beach (US).

From its Saint- Hilaire-de-Riez (85) Cable Landing Station, Orange will enable terrestrial connection to Telxius up to Paris, while Telxius will connect Orange to Ashburn from Virginia Beach.

This collaboration represents a strong transatlantic bridge as both companies can effectively provide multi- terabit capacity on this Europe-US route. It also reinforces Orange and Telxius’ respective positions to support the development of new digital usages for their international customers in Europe and America and bolsters the international leadership position of both companies on the wholesale market to better address the needs of content-providers and third-party operators.

“We are pleased to announce this agreement with Telxius, which will allow us to provide our customers with very high capacity end-to-end services, as well as network redundancy, on the strategic transatlantic route. We will be operating two fiber pairs of over 30 terabits per second between France and the USA. It is a valuable extension to Orange’s global network joining our Atlantic and Mediterranean routes to Africa, the Middle East and Asia with guaranteed best in class quality of service,” said Jerome Barré, CEO of Orange Wholesale and International Networks.

Google's Dunant cable leverages SDM for 250 Tbps capacity

Google's Dunant submarine cable system, which will link the U.S. and France, will be the first subsea cable to leverage space-division multiplexing (SDM), enabling 250 terabits per second capacity.

In a blog posting, Vijay Vusirikala, Director of Network Architecture and Optical Engineering at Google, says SDM will increase cable capacity in a cost-effective manner.

Dunant's design uses twelve fiber pairs and power-optimized repeaters. Whereas traditional subsea cables are powered from the shore end and rely on a dedicated set of pump lasers to amplify the optical signal for each fiber pair, SDM allows pump lasers and associated optical components to be shared among multiple fiber pairs.

The new technologies and advancements that fueled this year’s conference will set the stage for the industry’s next breakthroughs in 5G, artificial intelligence (AI), machine learning, intra- and inter- data center equipment, disaggregation and more.

The OFC technical Program Chairs, Shinji Matsuo, NTT Device Technology Labs, NTT Corp., Japan; David Plant, McGill University, Canada; and Jun Shan Wey, ZTE TX, USA, worked tirelessly to ensure the OFC program remained accessible and collaborative for the broader community.

“OFC 2020 has demonstrated that large conferences can engage participants across the globe utilizing the optical fiber communications technologies developed by experts in the field,” said Wey, Plant and Matsuo. “The research and innovations enabled by the OFC community have made OFC 2020 the perfect opportunity to run a virtual conference experiment.”

“The travel restrictions that arose due to the Coronavirus created a new dynamic for this year’s event,” shared the Program Chairs. “But by partnering with OFC management, we were able to rise to the challenge and offer a way for continued global collaboration throughout the event.”

As in previous years, this year’s plenary session was live-streamed, providing important insights to the broader optical communications community from three respected technical and commercial leaders in the field. Professor Sir David Payne, director, Optoelectronics Research Centre, University of Southampton, UK explored the role of silica in the future of optical communications, emphasizing its potential and challenging the audience to think differently about ways to tackle technical hurdles.

“Let me get to answer my initial question, ‘Is there a future for silica?’ Silica is not all done by any means. It’s very hard to beat for optical components largely because it’s a very refractory material,” Payne concluded.

Dr. Qi Bi, president, China Telecom Technology Innovation Center, CTO, China Telecom Beijing Research Institute provided a lessons-learned overview of China Telecom’s 5G deployment. “The ever-growing data rate of 5G is expected to revolutionize the way that we live and do business,” Bi shared. “Vendors need to think how we can do an integrated approach instead of an independent approach so we can have a much better handle on system integration.”

Dr. Benno Willke, research group leader, Max Planck Institute for Gravitational Physics, Germany, rounded out the session with a visionary talk that discussed plans for a third-generation of gravitational-wave detector.

A commemorative event, “Celebrating 50 Years of Light-speed Connections,” was held this year to recognize the importance of bringing low-loss optical fiber and room-temperature semiconductor lasers together in 1970 to transform global communications and enable light-speed connections across continents and oceans. Special programming featured a keynote address by Dr. David Welch, founder and chief innovation officer of Infinera Corporation, Sunnyvale, California, U.S.A, whose talk gave a glimpse into the near-term future, a show-floor exhibit on the history of fiber optics and a reception.

“Optical networks are central to global connectivity and global communication, and it has absolutely transformed our society and our world,” Welch remarked. “In the end, life is about human-to-human activity. We may elect to utilize machines to facilitate better human-to-human connectivity, and I think that is the greatest contribution of the optical network: the expanse of our human-to-human connectivity.”
