No Drift / High Precision USB Variable Attenuators (VOAs)
The High Precision Series VOA is an ideal variable optical attenuator providing near-perfect performances with a USB interface and user-friendly GUI. With a built-in position sensor, once the VOA’s attenuation value is set, it will remain at the value regardless of environmental variations. This series VOAs overcome the instability and drift issue associated with conventional VOAs. We produce three types to cover most application scenarios. The thermal actuated MEMS VOAs feature low loss and linear response. It is available with all types of fibers of 125 μm outer diameter and 0-5V analog control interface for OEM applications. We further produce high-speed feedback control VOAs with a faster response time of about 1 μs.
