    • InGaAs weak light coherent reception module 800-1700nm AC-1.6G

    IdealPhotonics has developed a high-speed, low-noise analog coherent receiving module for optical coherent detection applications. This SVDC power coherent receiver module integrates a high-speed, low-noise analog optoelectronic balanced detector and a high-quality fiber coupler. During the manufacturing process, the splitter ratio and length of the coupler are strictly controlled to further enhance the common-mode rejection ratio. Building on the coherent reception, to further improve the optical signal-to-noise ratio (SNR), the high SNR coherent receiving module integrates a low-noise small-signal fiber amplifier to amplify weak backscattered light signals. This module is suitable for fiber optic sensing, lidar, wind measurement radar, and other fields.
