High-Speed Bias Photodetectors Fiber-Coupled
The HSDT series High-Speed Fiber-Coupled Detectors are plug-and-play units featuring high-fidelity analog response with bandwidths up to 50 GHz. These biased detectors are ideal for measuring fast signal transients without distortion from amplification circuitry. Each unit integrates a high-speed InGaAs PIN photodiode operated in photoconductive mode with an internal reverse bias, providing a linear optical-to-electrical response without ringing and supporting input powers up to 10 dBm. The output is delivered via an RF SMA connector. Designed for high-speed photonics applications, HSDT detectors are suited for test and measurement tasks in data communications, analog microwave systems, and general photonic research.

Technical FAQ
Wavelength: 1310-1650nm. Check the High-Speed Bias Photodetectors Fiber-Coupled 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.
Power Supply: Non, Yes. 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.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
