MT-FA with the development of optical modules also ushered in new market demand.Different from the traditionalconnector, the crystal end face at the end of MT-FA cannot be directly physically connected, and the length of the deviceis generally short, so there are problems such as light leakage and inaccurate return loss test, and the polarity of fibercannot be tested with conventional polarity detector.Dimension Technology upgrades and iterates on the basis oimulti-core polarity insertion loss instrument to provide customers with a one-stop FAUMPER test solution, taking intoaccount the FA test of different branches and diferent angles, improving the eficiency of production inspe ction.

FA/JUMPER devices cannot connect to the MPO interface ofpolarity testers, making TOSA/ROSA array testing ineffective. 

Dimension Technology's patented visual polarity detection solves this problem. Integrated into the insertion and return loss meter, it enables one-step IL, RL, and polarity testingfor FA/JUMPER devices.

This testing solution can automatically test IL, RL, and polarity. For high-fiber-count arrays (2000+fibers), it uses a high-capacity integrating sphere. For multi-branch FA devices, the softwareintelligently organizes polarity sequences and generates a unified report.

Non-wrapped return loss meters, based on OTDR principles, have blind spots when testina uitra-short connectorswithout special handling. Wrapped return loss meters using OcWR also fail to test MT-FA device Rx end MT returnoss without matching gel. Dimension Technology has optimized the OTDR algorithm for FA-specific scenariosenabling detection of Rx end MT return loss.

Based on the optimized algorithm of Dimension Technology's multi-core polarity insertion and return loss meter the MT end return loss test results are stable and accurate when using matchinggel.
