MPO is the industry acronym for “multi-fibre push on.” Originally created in the late 20th century, MPO connector is the first generation of clip clamping multi-core optic fiber connector, which developed by the Japan NTT to easily interconnect multiple fiber strands and transfer an ever increasing amount of data.
While MTP is a registered trademark of US Conec, marketed as a “high performance MPO connector with multiple engineered product enhancements to improve optical and mechanical performance when compared to generic MPO connectors.” Both MTP connector and MPO connector are available with standard or elite / low loss options. The picture below shows the transmission of a 24-fiber MTP fiber connector.
