Seaborn Selects Xtera C+L-band repeaters for ARBR System
Seaborn Networks is to use Xtera’s C+L-band repeater design for its ARBR system and achieve on-demand capacities of up to 44 Tbits/s per fibre pair. The ARBR system runs between São Paulo and Buenos Aires, and will meet the growing capacity requirements of Internet Content Providers on this route. With direct onward connection to New York via Seaborn’s Seabras-1 system, it will also provide a lower latency route between the commercial and financial centres of Buenos Aires, São Paulo, and New York.
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 says development continues to increase the capacity on a fibre pair to well over 100 Tbits/s, further demonstrating that high capacity solutions do not have to mean large and costly fibre count systems.
“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 and CEO of Seaborn. “Use of Xtera’s andtechnology on the ARBR system will allow Seaborn to offer the most advanced system under the sea with on-demand capacities of up to 44 Tbits/s per fibre pair. Disruptive innovation like this resonates with our content provider customers and positions us to respond to their needs well into the future.”
“We are pleased to be able to offer a system solution that sidesteps the Shannon limit, matching Seaborn’s efforts to challenge the conventions of the industry, offering more to their customers and accomplishing this at a highly competitive price point,” adds Xtera’s COO Leigh Frame. “The combination of EDFA and Raman amplification allows us to provide C+L today, and Xtera is already innovating for what is beyond. We will continue to develop our products to stay ahead of market trends and help shape customer requirements, both commercially and technologically.”
The ARBR cable is fully funded and on an accelerated implementation schedule to bring new capacity on an underserved route.
