High Speed Premium Broadband Variable Optical Attenuator 350-2400nm, 120nm Coverage

SKU: NPBA

The Nano-speed Broadband Variable Fiber Optical Attenuator (NSBA) provides electrical control of optical power using a patent-pending configuration activated by a voltage signal. Its solid-state optical crystal design eliminates mechanical movement and organic materials, ensuring ultra-high reliability and fast response times. The NSBA supports a wide wavelength range and is packaged with a driver that includes an SMA 0-5V control input and a 12V power supply input. It is bidirectional, with two configurations: normally-transparent, where light passes through without applied voltage, or normally-opaque, where light is blocked without voltage. The wavelength range and attenuation levels depend on the number of electro-optic crystal stages, while response speed is influenced by attenuation level and driver power. Small attenuation levels can achieve response speeds up to MHz.
