Ultra-Low-Noise Polarization-Diversity Coherent Receiver Module UPDR-400M-A
Guangshi Technology's ultralow-noise polarization-diversity receiver module targets polarization-sensitive fiber sensing. It separately mixes the local oscillator with the two polarization states of the signal and receives them with two high-speed, low-noise balanced detectors, effectively resolving coherent polarization issues. Upgraded from the original PDR series, it greatly reduces background noise for a higher detected-signal SNR.

A microlens array (MLA) is a high-precision optical component composed of hundreds or thousands of tiny, uniformly arranged micro lenses on a single flat substrate. Unlike traditional single lenses that focus one light beam, a microlens array can split, homogenize, and reshape light on a micro scale. It is widely paired with VCSELs, lasers, and image sensors, becoming a core part of modern miniature optical systems.
