11 Mar 2009 Controlled modal filling in multimode optical fibers, expressed as Encircled Flux or Mode Power Distribution, is vital for modern datacomms systems. The Modal Explorer is quick and accurate at 850 and 1300nm and complies with the latest IEC standards.
Already used for measurements of VCSELs and LRMs, international standards bodies such as IEC and TIA are now adopting the measurement of Encircled Flux in an effort to improve repeatability of loss and bandwidth measurements for components used in 1Gb and 10Gb multimode systems.
