modulators, with a phase modulator superstructure
• 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
Applications
• 40 Gbps metro, regional and LH
optical networks
• 10 Gbps ULH optical networks
• Spectrally efficient DQPSK modulation
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 multisymbol 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 superstructure. The MZ
superstructure also functions as a phase (shifter) modulator.
DPMZ modulators are specifically designed to yield well-behaved and matching
electro-optic amplitude and phase responses over a 20 GHz frequency range and
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 modulator is designed with
the electrical I/O located on one side of the package. The two RF inputs use GPO
connectors. DPMZ modulators are packaged using our compact (6-mm high)
hermetic packaging technology.
The JDSU family of agile optical components includes modulators, switches,
attenuators, and tunable filters. These products provide the basis for spectrally
efficient DWDM transmission using dispersion-tolerant modulation. They
support a broad range of flexible functionalities at lower operating costs for agile
optical network. DPMZ modulators have a wide optical bandwidth, and are
compatible with full band tunable lasers in either C or L band.
