The High Precision Series VOA is based on a micro-electro-mechanical system (MEMS) device platform driven by a fast piezo actuator with a built-in high-precision optical position sensor. It uniquely offers near-perfect performance that is unmatched in the industry, including ultra-low insertion loss of 0.2dB, ultra-broadband from 200 to 2100nm, ultra-high setting/repeating precision of 0.1dB, high optical power handling up to 1W, and linear response. Once the VOA attenuation value is set, it will remain at the value regardless of environmental variations and the loss of electrical power. Light passes through the device with a thin index-matched gap without any optical coatings. It is available with all types of fibers with a 125-micron outer diameter. Other-diameter fibers can be accommodated with special order.
The VOA is driven by an attached PCB with USB or RS232 computer interfaces and GUI software.
