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.”

Ciena adds L-Band to its subsea GeoMesh Extreme

Ciena is boosting the horsepower of GeoMesh Extreme submarine solution by adding support for L-Band spectrum. The platform also gains the ability to operate on TE SubCom’s L-Band wet plant system, nearly doubling the information-carrying capacity of a submarine cable.

Specifically, in addition to current C-Band (~ 1530nm to 1565nm) spectrum, Ciena’s GeoMesh Extreme solution now opens up the L-Band (~ 1656nm to 1625nm) in the same optical fiber, doubling the carrying capacity of an undersea cable.

Some highlights:

  • The same technology used by Ciena’s C-Band SLTE, which is deployed worldwide, is ported to the new L-Band SLTE to ensure the highest level of performance. Ciena has already deployed in the L-Band over terrestrial networks for many years and will leverage this extensive knowledge, expertise, and field experience to ensure a seamless migration into the L-Band in submarine networks.
  • TE SubCom announced earlier in 2017 that it has demonstrated a new transmission record of 70.4 Tb/s capacity over 7,600 km. This record transmission is made possible utilizing SubCom’s C+L technology, effectively doubles the available transmission bandwidth of the repeater by an unprecedented factor of two in supported capacity per fiber pair when compared to the same number of fiber pairs in traditional C-Band technology.
  • Submarine cable operators will also benefit from Ciena’s advanced Blue Planet MCP solution that allows for managing the Ciena C/L-Band SLTE and TE SubCom C/L-Band wet plant from a single, unified management platform for a seamless, end-to-end, best-in-breed Open Cable.

“Our partnership with TE SubCom has been critical in ensuring that customers can meet demand growth while delivering the highest level of performance. Leveraging L-Band, over and above the traditional C-Band, changes the economics of submarine network connectivity by providing unprecedented improvements in capacity, reliability, and simplicity,” stated Steve Alexander, Chief Technology Officer, Ciena.
