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.”

Xtera in conversation with Verizon - part 2



In this segment, the conversation turns to network disaggregation trends. A key question that is raised by network operators is "what value am I going to get out of disaggregation if I am not interested in becoming an equipment manufacturer or system integrator?"  The value may be in standardizing APIs and driving network agility.

On the issue of standards, the topic of how to accurately quantify the capacity of open lines is raised, especially when spectral sharing is employed.

University College London carries 120 Terabit/s over a single repeatered fibre with Xtera

University College London (UCL), in collaboration with Xtera, has demonstrated the transmission of 120 Terabit/s over a single repeatered fibre.

The experiment used a hybrid distributed-Raman / EDFA amplifier with a bandwidth of 91 nm. This is an extension of the technology which Xtera currently deploys in its subsea repeaters, with 256QAM and adaptive FEC expertise coming from UCL and Z-PLUS Fiber 150 fibre from Sumitomo. These initial experiments were performed over 630 km with nine broadband amplifiers spaced at 70km.  In the near future, these will be connected to form a loop to allow tests over much longer distances.  The capacity and span achieved today exceeds the previous record of 115 Terabit/s over 100 km by more than six times.

Xtera said conventional approaches can yield bandwidths of approximately 70 nm when using the combination of a C-band and an L-band amplifier. Raman amplification used by Xtera can offer even greater bandwidth, in this case 91nm, while also offering very low noise. 

Dr. Stuart Barnes, Chairman of Xtera, in expressing how pleased he has been with the Xtera / UCL collaboration, states, “This is the start of an exciting period of work where Xtera and UCL will push the limits of this technology even further, a possibility which doesn’t exist for two discrete C+L amplifiers.  I am confident that more bandwidth is not only possible but also practical, and more importantly, commercially viable.  Xtera will continue to push transmission technology further in order to create products which meet the market demands of the future.”

Professor Polina Bayvel, CBE FRS FREng, adds, “I am happy that our state-of-the-art, high-speed WDM transmission testbed, developed through the EPSRC UNLOC programme, could be used to achieve record transmission throughput.  This accomplishment has been enabled by many ground-breaking research developments in digital signal processing and amplifier technology as well as dedicated effort of outstanding researchers from UCL’s Optical Networks Group and Xtera.”

Details of the experiment and findings are available at www.xtera.com/learning/ and www.arxiv.org

Seaborn and Grupo Werthein to build Argentina-Brazil Subsea Cable

Seaborn Networks, an independent developer-owner-operator of submarine cable systems, and Grupo Werthein, a major Argentine investment holding company with significant holdings in the telecommunications sector, announced a binding agreement for the construction of a new subsea optical cable system, named ARBR, connecting Argentina with Brazil.

The new ARBR cable system will additionally provide onward connectivity via Seabras-1, which is currently under construction, to enable a direct route between Argentina and the U.S. The ARBR system will be jointly developed and owned by Seabras Group, an affiliate of Seabras, and Werthein.

Seabras is the sole owner of the Seabras-1 submarine cable system between New York and Sao Paulo in Brazil, which was developed and is operated and owned by Seaborn Networks, in partnership with funds managed and/or advised by Partners Group, a global private markets investment manager.

Seabras noted that it has sold capacity on Seabras-1 to a variety of large and small telecommunications companies and other customers, both via indefeasible rights of use (IRUs) and on short-term lease agreements. As with Seabras-1, Seaborn will act as the operator of the ARBR system. Seabras stated that together the ARBR and Seabras-1 cables represent a total project value of more than $575 million.

The ARBR cable will be a four-fibre pair system with and will offer an initial maximum design capacity of 48 Tbit/s. The system has a scheduled completion date in the second half of 2018. The ARBR cable system's Brazil landing will be located in the existing Seabras-1 cable landing station in Praia Grande, Brazil, enabling direct onward connectivity to New York over Seabras-1. The Argentina landing for the new cable is expected to be in or near Las Toninas, to the south of Buenos Aires.

Xtera Supplies 100G for TIM Brasil in Amazonas

Xtera Communications supplied its 100G optical transport platform to TIM Brasil for a new infrastructure deployment connecting three cities in the Amazon: Manaus, Macapá and Belém.

Xtera’s Nu-Wave Optima 100G optical networking platform was used for a new optical backbone network that was built using the tower transmission lines and power substations of the LT Amazon consortium.  The TIM Brasil cables connect 27 cities in the states of Amazonas, Pará and Amapá. Given the challenging geography of this network environment, the lengths of 5 out of the 14 spans that make up this infrastructure exceed 200 km between sites where active optical equipment is positioned. The longest of these spans reaches nearly 260 km.

"The construction of the first 100G backbone in the Amazon is an innovative and challenging project, connecting one of the most important cities in the Amazon region – Manaus – that will host 2014 FIFA World Cup. This project will bring many benefits to the regional population and reinforces the commitment of TIM for expanding and improving its network throughout Brazil," says Cicero Olivieri, Director of Fixed & Transport Network of TIM Brazil. “We are pleased with the performance of Xtera’s technology, highlighted by the long-span capability and the minimal number of regeneration sites throughout the network, and with their commitment to take on the challenges inherent to any deployment in the Amazon Region."
