ESVOA
The ESVOA is based on micro-electromechanical (MEMS) technology. It manages optical power by changing the coupling efficiency of the device through voltage. MEMS VOA has the characteristics of small size, low power consumption, and fast response speed, making it particularly suitable for power management in WDM and PON systems.
