Description
The KY-PRM-XCH series multi-channel PIN photoreceiver integrates multi-channel of high linearity analog PIN detector and low noise broadband transimpedance amplifier with high gain, high sensitivity,AC coupling output and flat gain. The module is powered by positive 12V,and the fiber interface is universal for single-mode and multi-mode optical fiber. The electric signal is SMA output, mainly used in picosecond optical pulse detection, optical detection, laser radar, optical fiber sensing system and other fields.
