SKU: NVOA, NHOA
The Nano-speed Variable Fiber Optical Attenuator (NVOA) provides high-speed electrical control of optical power through a patent-pending configuration activated by a voltage control signal. Its solid-state optical crystal design eliminates mechanical movement and the need for organic materials, ensuring long-lasting durability and optimal performance. The NVOA Series Variable Optical Attenuators are engineered to meet demanding operational requirements, offering ultra-high reliability, rapid response times, and a compact footprint, as well as space qualification. The NVOA operates bidirectionally and is available in two configurations: Normally-transparent, where light passes through without voltage applied. Normally-opaque, where light is blocked until voltage is applied. The attenuation level is dependent on the operational stage, while the response speed is influenced by both the attenuation level and driver power (repetition rate). For lower attenuation levels, response times can reach up to the MHz range. Each NVOA unit is mounted on an electronic driving PCB board with a 0–5V control input, optimized for various repetition rates. Agiltron also offers customized electronic designs tailored to specific control requirements and applications.
