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.

The HSPD4040 high-speed detector module is designed for both digital and analog applications. The module contains an InGaAs PIN photodiode which response wavelength covers 1250 to 1650 nm and necessary matching electronics. HSPD4040 can provide the bandwidth upto 40GHz .  The module operates on +5V. It complies with a standard single-mode 9/125μm fiber input. The RF output port is a 2.92 mm connector matched by 50 ohm impedance . HSPD4040 is hermetically sealed, and weighs less than 20 grams. ROHS 2.0 certificated . 

To meet the demand of domestic customers for the full localization of high-speed detectors with amplification, Fiberwdm has launched a product with a bandwidth exceeding 20GHz. This series of high-speed detectors comes with built-in amplification and features extremely low noise. It can be used in high-speed communication systems and femtosecond laser system testing, making it a cost-effective, fully localized product. Fiberwdm has independently developed a linear power supply, which can fully meet the needs of high-speed detectors in scientific research applications.
