High Speed Premium Variable Fiber Optical Attenuator 350-2400nm, 18dB

SKU: NPOA, NPHA

The Nano-Speed Premium Variable Fiber Optical Attenuator (NPOA) provides fast electrical control of optical power. It utilizes special electro-optic crystals that feature lower driving voltage, faster response, and broader wavelength coverage compared to the standard NSOA. This is achieved through a patented configuration activated by a voltage electrical control signal. The solid-state optical crystal design eliminates mechanical movement and organic materials, ensuring high reliability and fast response with minimal mechanical footprint. The NPOA Series Variable Optical Attenuators are designed to meet the most demanding operational requirements, offering ultra-high reliability and fast response times, as well as vibration insensitivity. Agiltron also provides customized electronic designs to meet special control requirements and applications. The NPOA is bidirectional, available in either normally-transparent mode (light passes through without applied voltage) or normally-opaque mode (light is blocked without applied voltage). The attenuation level depends on the stage, and the response speed is related to the attenuation level and driver power (repetition rate), with small attenuations reaching MHz response rates. The NP Series VOA is mounted on a specially designed electronic driving PCB board with a 0~5V control input optimized for various repetition rates.
