Transmitters & Receivers
The HSFD is a fiber-coupled InGaAs PIN photodiode integrated with a high-speed transimpedance amplifier (TIA), supporting data rates up to 25 Gb/s with differential output. It offers a flat response across a wide operating temperature range and is available with single-mode and multimode fiber coupling options, making it versatile for various high-speed optical communication applications. The multimode fiber coupling uses fiber tip lens technology for high efficiency.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
12, 25 GHz Fiber Optical Amplified InGaAs PIN Photodiode: Laboratory optical integration depends on preserving the optical budget through the complete path. The 1230 - 1620 wavelength specification sets source and detector compatibility. The fiber/interface entry (SM28, 50/125) must match the connected components.

Technical FAQ
Fiber Type: SM28, 50/125 · Fiber Cover: 0.9mm tube, Bare fiber. 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.
Wavelength: 1230 - 1620. Check the Transmitters & Receivers 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.
Driver PCB: Non, Single Output, Differential. 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.
