Key Features • Monolithically integrated, parallel, high-speed MZ 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 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 m ultisymbol 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.
