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.
