1270~1330nm CWDM4 DFB（25G）

Macro channel water-cooled stacked laser diodes integrate dozens of laser bars into one vertical stacked module with large-diameter macro flow cooling channels.

The CNGE 384 uncooled infrared core module is a high-performance core component for thermal imaging systems. Adopting mature uncooled infrared detection technology, it realizes all-weather thermal radiation perception and high-definition imaging without refrigeration equipment.

VCSEL, short for Vertical Cavity Surface Emitting Laser, is a widely used semiconductor laser component in modern optoelectronics. Unlike traditional edge-emitting lasers, VCSEL emits laser light vertically from its chip surface. Thanks to its low power consumption, stable beam quality, low cost, and easy integration, it has become the core light source for 3D sensing, wearable devices, and high-speed optical communication.

Founded in Beijing in 2011, Beijing FJR Opto-electronic Technology Co., Ltd. specializes in R&D, manufacturing and sales of infrared thermal imaging equipment and complete optoelectronic systems.
