InGaAs weak light coherent reception module 800-1700nm DC-350M

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.

Product features：High bandwidth、 High gain、 Low noise、 Built-in low-noise isolation power supply
