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