High-Speed Detectors High-Speed Detectors HSPD4018 & HSPD4040
To meet domestic customers' demand for fully localized high-speed photodetector (PD) products, Fiberwdm has developed two high-speed PD products with bandwidths exceeding 18GHz and 40GHz after nearly 2 years of R&D and optimization. The 18GHz PD has a rise time of less than 20ps, and the 40GHz PD has a rise time of less than 8.5ps. Their responsivity is no lower than that of similar imported products from Finisar, Thorlabs, etc., and the tail oscillation is also well controlled. This series of high-speed detectors does not include a Transimpedance Amplifier (TIA) and features extremely low noise. It can be used for testing high-speed communication systems and femtosecond laser systems, and is a cost-effective fully localized product. The linear power supply independently developed by Fiberwdm can fully meet the requirements of high-speed detectors in scientific research applications.
