The High Precision Series VOA is based on a micro-electro-mechanical system (MEMS) device platform driven by a thermally activated MEMS blocker having a built-in high-precision optical position sensor. It uniquely offers advantageous performances, including low insertion loss, ultra-high setting/repeating precision of 0.1dB, and linearity. Once the VOA attenuation value is set, it will remain at the value regardless of the environmental variations and the loss of electrical power. It is available with SM, MM, and PM fiber.
The VOA is driven by an attached PCB having a USB with GUI software.
