Seaborn tests technology to boost Seabras-1 by 50%

Seaborn Networks says it could increase capacity of its new Seabras-1 subsea cable by 50% using new optical technology.

The cable company and its technology vendor, Infinera, say they have completed a trial on the newly opened cable that demonstrates much higher efficiency.

Larry Schwartz, chairman and CEO of Seaborn Networks, said: “The capacity upgrade maximises our return on investment and further underscores the uniqueness of Seaborn’s capacity on Seabras-1.”

The trial “demonstrated 4.5 bits per second per hertz on the Seabras-1 cable”, said Seaborn, over a distance of more than 10,500km. Seabras-1, which went into service earlier this month, links Brazil and the US.

Dave Welch, president and co-founder of Infinera, said the technology used “delivers industry-leading capacity-reach performance for our subsea customers where spectral efficiency is paramount and bandwidth demand is growing at more than 45% per year”.

The technology supports “up to 18.2Tbps per fibre for distances over 10,000km”, said Seaborn.

As Capacity reported this week, data center and connectivity service provider Ascenty is using Seabras-1 to connect its São Paulo and Vinhedo data centers in Brazil to the US.
