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."
