High Speed Dual-Stage Variable Fiber Optical Attenuator/Modulator

The NS Series Variable Fiber Optical Attenuator (VOA) provides electrical control of optical power. This is achieved using a patent pending non-mechanical configuration and activated via a voltage electrical control signal. The solid-state optical crystal design eliminates mechanical movement and organic materials. The dual-stage NS Series Variable Optical Attenuators are designed to meet the high attenuation in addition of ultra-high reliability and fast response time with minimal mechanical footprint. Photonwares also offers customized electronic designs to meet special control requirements and applications. This type of VOA  is bidirectional.

The NS Series VOA is available in either normally-transparent or normally-opaque configurations.

Photonwares’ PCB driver listed in the web is recommended to operate this device, featuring high efficiency and low cost with 12VDC power and 0-5V control input.
