Expanded Beam fibre optic connectors are designed to operate in harsh environments, they use non-physical contact fibre optic termini that are fully sealed behind an anti-reflective coated ball lens. This lens expands the beam to many times its original size aiding optical alignment and minimizing the effects of dust, debris, vibration, and other environmental conditions. Because there is no wear on the optical surfaces / end faces of the termini during use, the QPlex connector has excellent durability, in excess of 3,000 mating cycles, providing a long service life interconnect solution.

QPlex Connectors are used in Oil & Gas, Mining, Factory Automation, Heavy Equipment, Marine, Broadcast, Medical, Military, Aerospace, and Defense for Communications, Audio / Video, and Sensing Applications.
