Description

 The KY-APRM-20G series 20Gbps APD high speed photoreceiver integrates high-speed InGaAs APD avalanche photodiode, automatic gain control circuit and low-noise broadband transimpedance amplifier. It features high gain, high sensitivity, AC-coupled output and flat gain. The built-in temperature compensation circuit ensures the output stability of the photodetector module at different temperatures.The module is powered by DC 12V, the fiber interface is FC/APC, and the electrical signal is differentially output by the SMA port. It’s mainly used in high-speed fiber transmission systems, microwave photonic links and other fields.
