Description

The KY-ICR-BW coherent receiver module consists of two polarization beam splitters, a dual-polarization 90-degree optical mixer, four performance-matched balanced detectors and power and control circuits. The dual-polarization 90-degree optical mixer demodulates the incident signal light by an external reference light source, and is converted into an electrical signal by four balanced detectors, then amplified output low noise amplifier circuit. It features high gain, high linearity, high common-mode rejection ratio, AC-coupled output and flat gain. The module is powered by DC 5V, two fiber input ports, the fiber interface is FC/APC, and the electrical signal is output by SMA-type connector. It can choose three bandwidth applications of 10M, 200M and 1G. It’s mainly used in space optical communication system, DVS/DAS, and other optical fiber sensing system systems.
