Alcatel-Lucent Submarine Networks (ASN) and Nokia Bell Labs
today announced they have achieved a record transmission capacity
over a 6,600 km single mode fiber. The breakthrough lab trial
demonstrated a total 65 terabit-per-second (Tb/s) transmission
using submarine grade dual band erbium doped fiber amplifiers,
which will help extend the capability of transoceanic cable systems
to meet increasing data traffic demand. The trial
leveraged Bell Labs' new Probabilistic Constellation Shaping (PCS)
technology, a groundbreaking new modulation technique that
maximizes the distance and capacity of high-speed transmission in
optical networks. Unlike traditional techniques whereby all
constellation symbols are transmitted with the same occurrence, PCS
intelligently uses non-uniform transmission of constellation
symbols by reducing the occurrence of high power symbols, thus
providing more resilience to noise and other impairments, and the
ability to dynamically adapt to changing conditions. Using this
novel approach, the capacity of undersea cable systems can be
further maximized to help telecom and webscale operators address
increasing consumer and business data traffic demands. The capacity
of 65 Tb/s - equivalent to more than 10 million HDTV channels
streamed simultaneously - is 13,000 times the capacity that was
available on the first undersea amplified transatlantic system
installed in 1995.
Olivier Gautheron, chief technology officer
of ASN, said: "This new record is the latest in a long series of
achievements by Alcatel-Lucent Submarine Networks over the past 20
years, with breakthroughs that have transformed long distance data
transmission. It also underlines our strategic focus on R&D to
raise the bar for undersea fiber-optic technology as our
researchers continue to develop new solutions to help traditional
and webscale operators cope with increasing requirements for speed,
capacity and cost-effectiveness." Marcus Weldon, president of Nokia
Bell Labs & Nokia CTO, said: "The future digital existence
where everyone, everything and every system and process is
connected will require a massive increase in network capacity and
the ability to dynamically optimize this capacity. Probabilistic
Constellation Shaping extends the limits of current optical
transmission by utilizing novel modulation techniques to
dramatically improve the performance and capacity needed for the
new digital era that will be enabled by the Future X Network." In
September, Nokia Bell Labs, Deutsche Telekom and the Technical
University on Munich leveraged PCS technology to achieve speeds of
1 Tb per second per channel over Deutsche Telekom's terrestrial
optical network. It presented the results of this trial at the
Europe Conference on Optical Communications (ECOC) 2016 in
Dusseldorf, Germany. About Alcatel-Lucent Submarine Networks
