AGILE OPTICAL COMPONENTS
Key Features • Monolithically integrated parallel high speed MZ
modulators with a phase modulator
• High speed MZ modulators with matching amplitude and
phase response
• High Electro-optic bandwidth
• Compatible with full band tunable lasers
• Integrated RF power monitors for precision control
• Single-sided electrical I/O
The Dual Parallel Mach-Zehnder (DPMZ) modulator is ideally suited for use in
metro, long haul (LH) and ultra long haul (ULH) optical transport applications.
It is used for spectrally efficient multi-symbol transmission based on differential
quadrature phase shift keying (DQPSK) modulation. The DPMZ modulator is
comprised of two matched, high-speed Mach-Zehnder (MZ) modulators that are
monolithically integrated, in parallel, inside an MZ super structure. The MZ super
structure also functions as a phase (shifter) modulator.
DPMZ modulators have been specifically designed to yield well-behaved and
matching electro-optic amplitude and phase responses over 20 GHz frequency
range. The MZ modulators have been design to have enhanced extinction ratios.
The DPMZ is available with either single mode or polarization maintaining
output fiber.
For mounting convenience and space efficiency, the DPMZ is designed with the
electrical I/O located on one side of the package. It is packaged using JDSU’s
compact (6-mm high) hermetic packaging technology. The two RF inputs use
GPO connectors.
The JDSU Agile Optical Components family includes modulators, switches,
attenuators and tunable filters. These products provide the basis for spectrally
efficient DWDM transmission utilizing dispersion tolerant modulation. They
support a wide range of flexible functionalities at lower operational expenses for
the Agile Optical Network. DPMZ modulators have a wide optical bandwidth.
They are compatible with full band tunable lasers in either C or L band.
Applications
• 40 Gb/s metro, regional and LH
optical networks
• 10Gb/s ULH optical networks
• Spectral efficient DQPSK modulation
Compliance
• Telcordia GR-468
