The LC Duplex connector family is designed specifically for challenging environments such as outdoors. Typically an IP67 rating means that the connector can be ‘splashed’ or ‘rained on’. The official test involves submerging a mated pair to 1 meter depth for 30 minutes, with no water leakage observed. In addition, these connectors also withstand most common industrial liquids that they may come in contact with, a benefit when used in a factory environment.
