Large Core Fiber Optical Variable Attenuator

The NanoSpeed™ Large Core Variable Fiber Optical Attenuator (NSLA) provides electrical control of optical power. This is achieved using an electro-optic crystal between two crossed polarizers, activated via a voltage of the electrical control signal. The solid-state optical crystal design eliminates mechanical movement and organic materials. The NP Series Variable Optical Attenuators are designed to meet the most demanding operation requirements of ultra-high reliability and fast response time with minimal mechanical footprint. Our also offers customized electronic designs to meet special control requirements and applications. The NSLA is bidirectional. The NS Series VOA is available in either normally-transparent, in which the light passes through without applying a voltage, or normally-opaque, in which the light is blocked without applying a voltage.
