Precision Variable Optical Attenuator Programmable Array Turn-Key System

The VOA Array Rack System is highly versatile and capable of meeting performance requirements for all application scenarios. The system integrates monitoring power taps to provide high-precision control of laser output power. Power control is lower in cost than attenuation control. Many types of VOAs can be selected. MEMS VOAs offer low cost and 70dB shut-off. Electro-optical NanoSpeed TM VOAs offer a 300ns fast response and a high-speed laser power stabilization function that eliminates fluctuations and surges. Fiber-Fiber TM VOAs offer ultra-broadband coverage from 200 to 2500nm, compatible with all types of fibers and ultra-low insertion loss. The system is a modular pluggable design that accommodates any number of channels in a single system with various corresponding rack heights.
