Optical Modulators

High Speed Multimode Broadband Variable Fiber Optical Attenuator 200nm, 50 μm Core

The broad waveband NS Variable Fiber Optical Attenuator (NVOA) provides electrical control of optical power. This is achieved using our patent pending non-mechanical configuration and activated via a voltage electrical control signal. Our solid-state optical crystal design eliminates mechanical movement and organic materials. Our NVOAs are designed to meet the most demanding operation requirements of ultra-high reliability and fast response time with minimal mechanical footprint. The switch is bidirectional and broadband. This NVOA can be used as the intensity modulator as well. The broadband NS Series VOA is available in either normally-transparent or normally-opaque configurations. The NS Series VOA is controlled by 0~5V voltage with a specially designed electronic driver having performance optimized for various repetition rate.
