MPO fiber optic jumper, MPO (Multi-fiberPushOn) connector is one of the MT series connectors. The ferrule of the MT series uses two guide holes and guide pins with a diameter of 0.7mm on the left and right sides of the ferrule end face (also called PIN needle) for precise connection. MPO connectors and optical fiber cables can be processed to produce various forms of MPO jumpers. MPO jumpers can be designed with 2~12 cores, up to 24 cores, and 12-core MPO connectors are most used. The compact design of the MPO connector makes the MPO jumper more cores and smaller in size. MPO jumpers are widely used in the wiring process that requires high-density integrated optical fiber line environments, FTTX and 40/100GSFP, SFP+ and other transceiver modules or internal and external connection applications of equipment.
