JDSU Creates World's Smallest Tunable Optical Transmitter

New TOSA Bridges the Gap for Tunability and Pluggability Missing in Previous
Transceiver Offerings; Provides New Pluggable Solution to Support 50 GHz
Channel Spacing in Metro Networks

MILPITAS, Calif., Jan. 22 /PRNewswire-FirstCall/ -- JDSU
(Nasdaq: JDSU and TSX: JDU) today announced that it has created the world's
smallest widely tunable transmitter optical subassembly (TOSA) for the dense
wavelength division multiplexing (DWDM) transceiver market. The new TOSA
represents a dramatic reduction in size and cost compared to previous discrete
solutions for tunable transmitters.

The new TOSA brings full band tunability, or the ability for service
providers to change to any wavelength on demand, to pluggable small form
factor (XFP) transceivers that previously only supported one to two
wavelengths.
In addition, the new tunable TOSA will enable service providers to use
pluggable small form factor products to support 50GHz channel spacing in metro
area networks, as traffic continues to grow in this area due to increased use
of voice, video and data applications among consumers. According to a recent
report by analyst firm IDC, fastest growth in optical networking is expected
in the metro space over the next three years.
The TOSA houses JDSU's Integrated Laser Mach Zehnder (ILMZ) chip that was
announced in September 2007. The ILMZ is a photonic integrated circuit (PIC)
that combines a tunable laser and optical modulator on a tiny chip for
smaller, higher performance tunable solutions. JDSU produces the ILMZ using a
semiconductor style of manufacturing that allows this functionally integrated
optical solution to be produced in high volumes more quickly and efficiently,
resulting in lower costs.
"JDSU's new TOSA is the first of its kind and an exciting step forward for
the transceiver industry," said Alex Schoenfelder, vice president and general
manager of Integrated Photonics at JDSU. "Our ability to leverage the
expertise of JDSU's in-house datacom and telecom teams provided a competitive
advantage when it came to packing the most innovation possible into a
dramatically smaller assembly."
TOSAs reside within optical transceivers -- the key interface to optical
networks that convert electrical data to optical signals and back again as
they travel through DWDM networks.
JDSU will offer transceiver products leveraging the new TOSA package to
the market later this year.
