Long-
distance data
transmission
Alcatel-Lucent Submarine Networks
(ASN), the undersea cables subsidiary
of Alcatel-Lucent, has achieved a
breakthrough record of data transmission
over a distance of 10,000km. The trial
used real-time processing prototypes of a
new, cost effective, 300GBp/s modulation
technology, designed to optimise the
performance of submarine cable systems.
The trial has been achieved on the
10,000km of ASN’s test bed, combining
the innovative 300G 8QAM (8 quadrature
amplitude
modulation)
technology
of ASN’s 1620 Softnode platform and
second-generation coherent submarine
fibre (CSF-2).
8QAM technology can optimise both new
and existing undersea cable systems,
enabling operators to deliver over
15Tbit/s per fibre pair on transoceanic
systems – equivalent to 2.25 million
simultaneously streamed HDTV channels.
Olivier Gautheron, chief technology
officer of Alcatel-Lucent submarine
networks,
said: “This
breakthrough
underlines ASN’s strategic focus in R&D
to raise the bar for undersea fibre optic
technology. Our researchers continue to
develop new solutions to further apply
our own innovation to help traditional
and web-scale operators cope with
increasing requirements for speed,
capacity and cost-effectiveness.”
Leveraging the largest research and
development
capabilities
in
the
submarine cable industry, ASN has
achieved several breakthroughs in both
repeatered and unrepeatered submarine
cable systems.

ABB has placed an order for what is
believed to be the world’s most advanced
cable-laying vessel. The new 140m ship
will be custom-built at Kleven shipyard in
Norway, with delivery expected in 2017.
The vessel will be constructed in such
a way that fire and flooding can be
contained and will not compromise
positioning and other essential systems.
