BPD-003 OEM Balanced Photodetector
Product information "BPD-003 OEM Balanced Photodetector"
InGaAs Photodetector; 1060, 1310, 1550 nm; Aluminium Enclosure; Responsivity >0.5->0.8 mA/mW; RF Bandwidth 0-200 MHz; Transimpedance Gain 100×103 V/A
OCT and sensor systems require high performance balanced photodetectors to boost system signal-to-noise ratio (SNR). General Photonics’ BPD-003 OEM balanced photodetector module is specially designed for OEM applications in such fields, engineered for low cost and small size as well as high performance.
The BPD-003 device consists of an optical head and a post-amplification board with an SMA or SMB RF output connector. The optical head has two input fibers aligned with a pair of matched photodetectors, selected for high CMRR and sensitivity, followed by an integrated low-noise transimpedance amplifier (TIA) placed immediately after the photodetectors to amplify received signals with low noise and enhanced CMRR.
The integrated post-amplification circuit further conditions and amplifies the output of the detectors to a range of ± 3.5 V maximum. With a bandwidth of up to 200 MHz and a high conversion gain, the BPD-003 is ideal for integration into OCT, fiber sensor and high-performance optical measurement systems.
