Nokia Corporation (ADR)(NYSE:NOK)
and Siemens have come together in a joint venture called Nokia Siemens Networks,
with a consortium of R&D partners to showcase a capacity record using light
to transmit information down commercially deployed multi-mode optical fiber.
There was a 6-fold increase in optical data speed to 57.6 terabit per second
(Tbps), as compared to 9.6 Tbps speed available with today’s commercial
systems.

The technology involves spatial
multiplexing over solid-core multi-mode fiber, which has been recognized at the
European Conference on Optical Communications (ECOC). Robert Richter, head of
R&D optical networks at Nokia Siemens Networks states that double the
capacity needed for 7 billion people can be transmitted over a single fiber,
thanks to this record data rate. With advanced technology, a single fiber will
be able to transmit 40 million different TV streams simultaneously someday.
Hollow-core photonic band gap
fibers along with the spatial multiplexing technology will affect the world
economy too because high-frequency trading firms constituting 73% of the entire
US equity trading volume will gain immensely due to the low latency of optical
transmission.
ModeGap consortium has taken care
of the technicalities, whose members comprise Networks, the University of Southampton
and the Technische Universiteit Eindhoven, and others. The consortium is
focusing on developing components, fiber and digital signal processing concepts
for spatial multiplexing over photonic band gap fibers in the 1.55 and 2
micrometer region.
