Variable Optical Attenuators

Multi-Channel VOA Array with Integrated Monitor

The Multi-channel Variable Fiber Optical Attenuator with Integrated Power Monitor Module (VOA-TAPM) is designed to provide the precision control of a steady output optical power or attenuation independent of environmental variations or input laser instability. The input-tap and output-tap are integrated with VOAs in a compact module. The module eliminates laser power variations, such as PDL, WDL, TDL, etc., and is particularly suitable for continuous optical power regulation and transient optical suppression, as well as analog signal modulation applications. The module is a platform ready for customization with a control electronics option.
