Google to build private "Dunant" cable from Virginia to France

Google is planning a new transatlantic subsea cable system linking the east coast of the United States to Europe to bolster its global network.

Dunant, which is named in honor of Swiss businessman and humanitarian Henri Dunant, will be a four-fiber pair cable system spanning over 6,400km from Virginia Beach to the French Atlantic coast.

Google has selected TE SubCom to build the Dunant submarine cable system. Activation is expected in late 2020.

Google said it continues to consider three options when considering its subsea connectivity needs: (1) purchasing capacity on existing cables (2) joining a consortium to build new cables (3) building a private cable system. In this case, there is a growing need for capacity between its cloud data center regions in Virginia and Belgium.

“We are proud to be working with Google on this important cable system and to be helping to increase internet performance for all,” said Sanjay Chowbey, president of TE SubCom. “The Dunant cable system will be built using SubCom’s industry-leading A1 cable family, which is optimized for projects compatible with higher DCR. As a leading supplier of submarine cable systems, we look forward to continuing to work with our global partners to create more accessible and faster internet access.”

Henri Dunant was the founder of the Red Cross and recipient of the first Nobel Peace Prize.

Google commissions own subsea cable from CA to Chile

TE Subcom has been awarded a contract by Alphabet, the parent company of Google, to build a subsea cable from California to Chile. A ready-for-service date is expected in 2019.

The Curie Submarine Cable will be a four fiber-pair subsea system spanning over 10,000 km from Los Angeles to Valparaiso. It will include a branching unit for future connectivity to Panama.

The project is believed to be the first subsea cable to land in Chile in 20 years.

Google joins Havfrue and HK-G subsea cable projects

Google announced its participation in the HAVFRUE subsea cable project across the north Atlantic and in the Hong Kong to Guam cable system, both of which are expected to enter service in 2019.

In addition, Google confirmed that it is on-track to open cloud regions (data centers) in the Netherlands and Montreal this calendar quarter, followed by Los Angeles, Finland and Hong Kong.

HAVFRUE is the newly-announced new subsea cable project that will link New Jersey to the Jutland Peninsula of Denmark with a branch landing in County Mayo, Ireland. Optional branch extensions to Northern and Southern Norway are also included in the design. The HAVFRU system will be owned and operated by multiple parties, including Aqua Comms, Bulk Infrastructure, Facebook, Google and others. Aqua Comms, the Irish cable owner/operator and carriers’ carrier, will serve as the system operator and landing party in U.S.A., Ireland, and Denmark. Bulk Infrastructure of Norway will be the owner and landing party for the Norwegian branch options. The HAFVRUE subsea cable system will be optimized for coherent transmission and will offer a cross-sectional cable capacity of 108Tbps, scalable to higher capacities utilizing future generation SLTE technology. SubCom will incorporate their Wavelength Selective Switching Reconfigurable Optical Add Drop Multiplexer (WSS-ROADM) for flexible wavelength allocation over the system design life. It is the first new cable system in almost two decades that will traverse the North Atlantic to connect mainland Northern Europe to the U.S.A. TE Subcom is the system supplier.

The 3,900 kilometer Hong Kong - Guam Cable system (HK-G) will offer 48 Tbps of design capacity when it comes into service in late 2019. It features 100G optical transmission capabilities and is being built by RTI Connectivity Pte. Ltd. (RTI-C) and NEC Corporation with capital from the Fund Corporation for the Overseas Development of Japan's ICT and Postal Services Inc. (Japan ICT Fund), along with syndicated loans from Japanese institutions including NEC Capital Solutions Limited, among others. In Hong Kong, the cable is slated to land in Tseung Kwan O (TKO) and will land in Piti, Guam at the recently completed Teleguam Holdings LLC (GTA) cable landing station. HK-G will land in the same facility as the Southeast Asia - United States Cable System (SEA-US).

Google also noted its direct investment in 11 cables, including those planned or under construction:

NEC and Google test subsea modulation using probabilistic shaping

NEC and Google have tested probabilistic shaping techniques to adjust the modulation of optical transmission across the 11,000-km FASTER subsea cable linking the U.S. and Japan.

The companies have demonstrated that the FASTER open subsea cable can be upgraded to a spectral efficiency of 6 bits per second per hertz (b/s/Hz) in an 11,000km segment -- representing a capacity of more than 26 Tbps in the C-band, which is over 2.5X the capacity originally planned for the cable, for no additional wet plant capital expenditure. The achievement represents a spectral efficiency-distance product record of 66,102 b/s/Hz.

The field trial was performed with live traffic on neighboring channels.

The companies said their test used near-Shannon probabilistic-shaping at a modulation of 64QAM, and for the first time on a live cable, artificial intelligence (AI) was used to analyze data for the purpose of nonlinearity compensation (NLC). NEC developed an NLC algorithm based on data-driven deep neural networks (DNN) to accurately and efficiently estimate the signal nonlinearity.

"Other approaches to NLC have attempted to solve the nonlinear Schrodinger equation, which requires the use of very complex algorithms," said NEC's Mr. Toru Kawauchi, General Manager, Submarine Network Division. "This approach sets aside those deterministic models of nonlinear propagation, in favor of a low-complexity black-box model of the fiber, generated by machine learning algorithms. The results demonstrate both an improvement in transmission performance and a reduction in implementation complexity. Furthermore, since the black-box model is built up from live transmission data, it does not require advance knowledge of the cable parameters. This allows the model to be used on any cable without prior modeling or characterization, which shows the potential application of AI technology to open subsea cable systems, on which terminal equipment from multiple vendors may be readily installed."

Transpacific FASTER Cable Enters Service with 60 Tbps Capacity

The world's highest capacity undersea cable system has entered commercial service -- six fiber pairs capable of delivering 60 Terabits per second (Tbps) of bandwidth across the Pacific.

FASTER is a 9,000km trans-Pacific cable connecting Oregon and two landing sites in Japan (Chiba and Mie prefectures). The system has extended connections to major hubs on the West Coast of the U.S. covering Los Angeles, the San Francisco Bay Area, Portland and Seattle. The design features extremely low-loss fiber, without a dispersion compensation section, and the latest digital signal processing technology.

Google will have sole access to a dedicated fiber pair. This enables Google to carry 10 Tbps of traffic (100 wavelengths at 100 Gbps). In addition to greater capacity, the FASTER Cable System brings much needed diversity to East Asia, writes Alan Chin-Lun Cheung, Google Submarine Networking Infrastructure.

Construction of the system was announced in August 2014 by the FASTER consortium, consisting of China Mobile International, China Telecom Global, Global Transit, Google, KDDI and Singtel.

Xtera's subsea repeaters enable C+L transmission on Seaborn's ARBR cable

Seaborn Networks will use Xtera’s wideband repeater to enable C+L band capability for its new ARBR cable between São Paulo and Buenos Aires.

The ARBR submarine fibre optic cable system, which is a fully-funded project developed jointly by Seaborn Networks and the Werthein Group. The 2,700 km open system, 4-fibre pair, 48Tbps, direct PoP-to-PoP subsea cable will connect Argentina and Brazil. The ARBR subsea cable system will allow for direct onward connectivity to New York, via the new Seabras-1 system.

Xtera’s wideband repeater is a hybrid Raman / EDFA design and can be configured to provide bandwidth in the C band alone, or across the C+L bands. First deployed in 2015, Xtera’s addition of Raman amplification to standard repeater technology has been used to achieve bandwidths of approximately 70 nm, while also offering very low noise solutions. Xtera said development continues to increase the capacity on a fibre pair to well over 100Tbit/s, further demonstrating that high capacity solutions do not have to mean large and costly fibre count systems.

In comparison, standard subsea repeaters use a single frequency band to carry the traffic. Seaborn said that by putting both the C and L frequency bands into ARBR’s cable on a fiber pair basis, it can pick and choose which fiber pair uses both bands and which use a single band, therefore enabling a choice between the most cost-efficient deployment of a fiber pair (single band) or an ultra-high capacity fiber pair (C+L). Seaborn is therefore able to tailor the subsea solution of each fiber pair to match the needs of different customers. For instance, carriers, ISPs and enterprise customers need affordable bandwidth from Argentina, whereas hyper-scalers need the assurance of ultra-high capacity throughout the life of the cable system.

“We work constantly with our partners and customers in this dynamic Latin American market to develop subsea cable systems that meet their future bandwidth demands,” says Larry Schwartz, Chairman & CEO of Seaborn. “Use of Xtera’s technology on the ARBR system will allow Seaborn to offer the most advanced system under the sea with on-demand capacities of up to 44Tbit/s per fiber pair. Disruptive innovation like this resonates with our content provider customers and positions us to respond to their needs well into the future.”
