MP-732T/R-MM Electro-Optic Conversion Module

Overview

The MP-732T/R-MM Electro-Optic Conversion Module is an OEM-grade, fiber-coupled transducer engineered for high-fidelity analog conversion of electrical signals into modulated optical output. Based on lithium niobate (LiNbO₃) Mach–Zehnder interferometer architecture, this module leverages the linear electro-optic Pockels effect to achieve broadband, low-distortion intensity modulation across standard telecom wavelengths (1310 nm and 1550 nm). Designed for integration into laboratory test benches, photonic integrated circuit (PIC) characterization setups, and optical communication subsystems, it delivers stable performance under continuous-wave (CW) and pulsed RF drive conditions. Its compact hermetically sealed housing ensures mechanical robustness and long-term polarization stability—critical for coherent detection, optical time-domain reflectometry (OTDR), and analog photonic link applications requiring phase coherence and amplitude linearity.

Key Features

• Lithium niobate (LiNbO₃) waveguide platform with titanium in-diffused optical path for low propagation loss and high electro-optic efficiency
• Dual-wavelength operation at 1310 nm and 1550 nm, supporting C-band and O-band system validation
• 10 MHz analog modulation bandwidth optimized for baseband signal integrity and harmonic suppression
• FC/PC or FC/APC fiber pigtails with factory-aligned polarization-maintaining (PM) fiber output (optional)
• Integrated DC bias control port enabling quadrature-point stabilization and dynamic operating point adjustment
• 50 Ω RF input impedance matched to standard signal generators and vector network analyzers (VNAs)
• Hermetic metal-ceramic package compliant with Telcordia GR-468-CORE reliability standards for extended operational lifetime

Sample Compatibility & Compliance

The MP-732T/R-MM is compatible with single-mode fiber (SMF-28 or equivalent) and polarization-maintaining fiber (PANDA or Bow-tie type) configurations. It meets IEC 61300-2-1 (vibration), IEC 61300-2-5 (impact), and IEC 61300-2-17 (temperature cycling) for passive optical components. While not a standalone medical or safety-certified device, its design adheres to laser safety Class 1 requirements when operated within specified optical power limits (< +10 dBm). The module supports traceable calibration documentation per ISO/IEC 17025 guidelines upon request and is suitable for use in environments governed by GLP-compliant optical metrology workflows.

Software & Data Management

As a hardware-level transduction component, the MP-732T/R-MM does not include embedded firmware or onboard software. It operates transparently within external instrumentation ecosystems—including Keysight PXIe-based RF signal generators, Tektronix optical modulation analyzers, and MATLAB/Simulink real-time control platforms via analog voltage control interfaces. For system-level traceability, users may log operational parameters (bias voltage, RF drive level, ambient temperature) using LabVIEW or Python-based DAQ frameworks. When deployed in regulated environments, configuration records and calibration logs can be maintained in accordance with FDA 21 CFR Part 11 requirements through validated electronic lab notebook (ELN) systems.

Applications

• Analog photonic links for antenna remoting and microwave photonics (e.g., radar front-end signal distribution)
• Optical carrier generation and sideband suppression in RF-over-fiber (RFoF) transmission systems
• Dynamic calibration of optical power meters and photodetector linearity verification
• Modulation transfer function (MTF) characterization of photonic receivers and demodulators
• Education and research in electro-optic modulation theory, including chirp analysis and bias drift compensation
• Integration into quantum optics testbeds requiring low-noise, high-extinction-ratio optical switching

FAQ

Is the MP-732T/R-MM compatible with both CW and pulsed RF inputs?
Yes—it supports continuous-wave and modulated RF signals up to 10 MHz; pulse rise/fall times are limited by the module’s intrinsic RC time constant and should remain >35 ns for optimal fidelity.
Can the optical output polarization state be actively controlled?
The standard version uses non-PM fiber; however, a PM-fiber-pigtailed variant with defined slow-axis alignment is available under custom order (Model suffix “-PM”).
What is the recommended DC bias voltage range for quadrature operation?
The nominal quadrature bias point is +3.2 V ±0.5 V (typ.) at room temperature; active feedback stabilization is advised for long-duration measurements.
Does this module require external temperature control?
No active thermo-electric cooler (TEC) is integrated; however, operation above 60 °C may induce drift in bias point and extinction ratio—environmental thermal management is recommended for metrology-grade use.
Is NIST-traceable calibration provided with shipment?
Calibration certificates are optional and available upon request; they include insertion loss, extinction ratio, and RF-to-optical responsivity (V/√mW) measured per IEC 61280-2-9.
