Photo IC for Fiber Amplifier
Photo IC for Fiber Amplifier
A new photodetector IC for fiber amplifiers that outputs the incident light signal as an analog voltage waveform.
Our proprietary photodetector element achieves low capacitance and low noise. It adopts our proprietary shield structure, which is unaffected by external electromagnetic noise, and a built-in filter reduces output noise.
Features
- Frequency 100kHz
- High linearity
- Low noise: noise equivalent power level −95dBm (0.3pW TYP)
- Resistant to external electromagnetic noise (proprietary shield structure)
- Built-in filter reduces output noise
- Light-receiving surface size (1.2mm×1.2mm)
