PARIS, February 27 /PRNewswire-FirstCall/ — Alcatel-Lucent (Euronext
and NYSE: ALU) today announced, in four post deadline papers accepted at
the OFC/NFOEC conference in San Diego, California, new optical networking
milestones, including a new optical transmission record and three novel new
photonic integrated circuits.
In a post deadline paper, Bell Labs researchers in its Villarceaux,
France center, in partnership with Alcatel-Thales’ III-V Lab and the
optical solution company Kylia announced the successful transmission of
16.4 Terabits per second of optical data over 2,550 km. This transmission
was achieved using 164 Wavelength-Division Multiplexed (WDM) channels
modulated at 100 Gbit/s and represents a world record for capacity x
distance at 41.8 Petabits/s.km. Several new technologies were used,
including a highly-linear, balanced optoelectronic photoreceiver and an
ultra-compact, temperature-insensitive coherent mixer. This result is a
critical step forward in enabling 100 Gbit/s Ethernet. It ensures the
maximum exploitation of the fibre bandwidth to cope with future capacity
needs, by providing very high information spectral density at 2bit/s/Hz.
Three other papers from Bell Labs researchers at Holmdel, NJ were
accepted. They describe the development of three new photonic integrated
circuits developed to achieve 100 Gbit/s with a high spectral efficiency.
In the first of these papers researchers developed an integrated high-speed
receiver using DQPSK modulation that is about 1,000 timers smaller than
existing DQPSK receivers which are built out of discrete components. This
new receiver could significantly lower the cost and size of 100 Gbit/s
components. Another of these papers demonstrated a dual-polarization
modulator with a 40 Gbit/s data stream in one polarization and a different
40 Gbit/s data stream in another one. This technique doubles the capacity
of a link without requiring any additional bandwidth. The last paper in
this series presents a modulator producing a 16-QAM signal format, used for
systems with extremely high spectral efficiency. While this format is well
known in wireless and satellite communications, its use in optics is new.
“These breakthroughs highlight the depth and breadth of the work done
by Bell Labs researchers in optical networking and physical technologies
around the world, and show how they must constantly improve and innovate
across various technical areas, to pave the way to the future of
communications” said Gee Rittenhouse, Research VP at Alcatel-Lucent’s Bell
Labs. “Particularly interesting is that these papers highlight the many
different dimensions of optical networking research that the new Bell Labs,
the result of the merger between Bell Labs and the former Alcatel’s R&I, is
doing to advance optical networking and give Alcatel-Lucent powerful
innovations to continue to be a leader in this space.”
