780nm PM acousto-optic modulator (operating frequency 80MHz, FC/APC)

Idealphotonics' acousto-optic modulators are widely used in optical fiber sensing applications due to their high modulation extinction ratio, high power tolerance, and other advantages. This product is specifically designed to meet the application needs of optical fiber sensing, featuring small size, low power consumption (less than 1W), fast rise time (12ns), good modulation pulse shape (low overshoot), and excellent pulse repeatability (small jitter in repetition period). Additionally, it can integrate the modulator and driver into a single package, making it convenient for system integration. It is widely applicable in various optical fiber sensing systems that require pulse modulation, such as φ-OTDR, BOTDR, and OFDR.

Product features：Small size、 Low power consumption（＜500mW）、 Fast rise time（12ns）、 Good modulation pulse shape (low overshoot)

Application area：Fiber optic sensing、 LiDAR、 BOTDA
