MT ferrules are widely applied in multiple optical connectors like MPO/MTP, QSFP+ transceivers, active optical cables (AOC cable), and also suitable for custom designed passive or active fiber coupling packages. Fiber is secured to the ferrules with an optical connector grade thermal cure epoxy and can be polished with specially made Flock Pile Polishing Films. XYT has designed Polishing Film that achieves geometry and fiber height requirements consistently in your MT connector polishing operation.
