Lithium Niobate Fiber Optical Modulator Auto-Bias Controller – Ensure Performance
The LNBC series bias controllers enhance the performance of intensity modulators by automatically biasing and stabilizing them at the quadrature point. This is achieved by injecting a low-frequency, low-amplitude dither signal and using built-in photodetectors to form a feedback loop for bias control. This loop helps maintain optimal performance and minimize temperature dependence. The bias is applied via an integrated microheater. The LNBC is designed for use with thin-film lithium niobate modulators that have integrated detectors and microheaters inside the modulator.

System integration
Integration and compatibility
Use these checks to connect Lithium Niobate Fiber Optical Modulator Auto-Bias Controller – Ensure Performance to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- Host interface: USB / RS-232 / manual interface
- 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.
- Control interface
- Power Supply: No, Yes · Controller type: Lithium niobate (LiNbO3) modulator auto-bias controller (LNBC series)
- 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.
