The MX connector series represents a major breakthrough for fiber in field production. Using advanced expanded beam technology, this is the most dependable, easiest to maintain fiber connector available. Unlike conventional pin-and-socket butt-joint connectors, the MX mating interface consists of easy to clean lenses. There are no recesses to trap dirt or interfere with signal transfer. Cleaning is simply a matter of wiping off the lenses with a lint-free cloth.
