ModCon Mode Controller is an innovative solution designed to enhance the accuracy and reliability of fiber optic measurements. This compact and lightweight module seamlessly integrates with your existing LED or VCSEL light sources, transforming them to deliver consistent Encircled Flux (EF) compliant launch conditions. This ensures that your light source meets the rigorous standards set by IEC 61280-4-1:2009, providing stability and repeatability in your measurements. Ensuring precise measurements in multi-mode fibers is crucial, as the modal condition of the light source can significantly impact results. Traditional measurement tools like OTDRs and LS/PM devices often yield varying results due to differences in the light sources used. The ModCon Mode Controller addresses this issue by standardizing the modal distribution, regardless of the source, thus minimizing uncertainties and enhancing measurement accuracy. By utilizing the ModCon, you can achieve better consistency and agreement between different test data sets, making it an essential tool for any professional seeking to comply with international standards. Each ModCon unit undergoes thorough testing with Arden’s MPX Modal Explorer, guaranteeing that its output meets the necessary standards. For added assurance, a Certificate of Conformance or Test Sheet is available to support your equipment record-keeping needs. The ModCon Mode Controller represents a simple yet effective method for improving measurement reliability in fiber optic testing.
