The JDS Uniphase SA-Z332A1 is a dual parallel Mach-Zehnder (DPMZ) modulator engineered for high-speed optical transport in metro, regional, long-haul, and ultra-long-haul telecommunications networks. This monolithically integrated device combines parallel high-speed Mach-Zehnder modulators within an MZ superstructure that also functions as a phase modulator, enabling spectrally efficient DQPSK modulation across 40 Gb/s and 10 Gb/s applications.
## Technical Specifications
• Modulator architecture: dual parallel Mach-Zehnder with integrated phase modulation
• Electro-optic bandwidth: high with well-matched amplitude and phase responses across 20 GHz frequency range
• Extinction ratio: enhanced performance; 15 dB ER achievable with 12.5 Gb/s 231-1 PRBS signal under specified operating conditions
• Optical bandwidth: wide; compatible with full-band tunable lasers in C or L band
• Electrical interface: single-sided I/O with two RF inputs via GPO connectors
• Package: 6 mm height, hermetic construction
• Output fiber: single-mode or polarization-maintaining options
• Compliance: Telcordia GR-468
## Key Features
• Monolithic integration of parallel modulators for compact footprint and reduced package height
• Flat electro-optic response over 20 GHz enables broadband modulation without equalization
• Single-sided electrical architecture simplifies RF drive circuitry
• Hermetic 6 mm package ensures long-term reliability in deployed systems
• Maximum driving voltage requirement dependent on operating wavelength and temperature range to maintain 15 dB extinction ratio
## Typical Applications
• 40 Gb/s metro and regional optical networks
• Long-haul (LH) optical transport systems
• 10 Gb/s ultra-long-haul (ULH) networks
• DQPSK modulation in spectrally constrained transport environments
## Compatibility & Integration
The SA-Z332A1 integrates with C-band and L-band tunable laser sources across their full operating ranges. Dual GPO RF connectors accept standard test equipment outputs. Available with either standard single-mode or polarization-maintaining fiber for output coupling.
