Xtera®, the system supplier for the ARBR project, announced that Seaborn Networks (“Seaborn”) has selected its C+L band design for the system between Sao Paulo and Buenos Aires. ARBR utilizes the advanced technology of Xtera in order to meet the growing capacity requirements of Internet Content Providers on this crucial route. The ARBR system will allow for direct onward connectivity to New York, via Seaborn’s Seabras-1 system, thereby providing a lower latency route between the commercial and financial centers of Buenos Aires, São Paulo, and New York. Xtera’s proven 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. 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.
