MTP OverviewWhat is an MPO Connector?The MPO connector family is defined by IEC-61754-7.The MTP multi-fiber connector is US Conec’s trademarked namefor our MPO connector. The MTP connector is fully compliant withIEC-61754-7; therefore it is an MPO connector.While there are many MPO connectors on the market (Furukawa,Sumitomo, Fujikura), the MTP parts are distinctly different. TheMTP connector is a high performance MPO!1/14/2003 2
