Balanced Photodetector Modules

Dual-path balanced photodetectors for interferometric and differential optical measurements — widely used in fiber sensing demodulation and coherent detection systems.

they are widely used in coherent detection applications for distributed fiber optic sensing, and in scenarios such as wind measurement radar.
BPD465 Balance Detector 10M-400MHz for OCT, Fiber Optic Sensing Systems, Wind Radar
The balanced photodetector contains two photodiodes and a low-noise transimpedance amplifier, in which the two photodiodes are matched to each other for excellent common mode rejection ratio
