Optical Modulators
This series of Lithium Niobate (LiNbO3) fiber optic modulators employs a Mach–Zehnder interferometer structure for optical power modulation with low drive voltage, utilizing a traveling push-pull waveguide electrode design. Each Z-cut device integrates a bias control section featuring a built-in micro-heater and an optical power monitor, enabling precise bias adjustment while monitoring output intensity for optimal performance. To compensate for DC drift and maintain the optimal bias point, an optional automatic bias control (ABC) version is available; when selected, the modulator is mounted on a PCB and fully tested prior to delivery. Additionally, a push-pull configuration is available that features two RF driving inputs to achieve zero-chirp operation when driven at a 180° phase difference.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
25GHz Lithium Niobate Waveguide Fiber Optical Intensity Modulator: Optical modulation depends on preserving the optical budget through the complete path. The 1520-1620nm wavelength specification sets source and detector compatibility. The fiber/interface entry (PM1550) must match the connected components. The 25GHz dynamic specification sets the usable control bandwidth.

Technical FAQ
Input Fiber: PM1550 · Output Fiber: PM1550. Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
Wavelength: 1520-1620nm. Check the Optical Modulators passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
Bias Controller: Non, Yes · RF Driver: Non, 4V, 8V. Match supply voltage, analog or digital command range, connector pinout and default optical state to the instrument interlock. Confirm the unpowered state explicitly — it decides what happens to the link on a power failure.
