Expanded beam simply means that the fiber optic connector end face has been manipulated in some way to over size the launch and receive point of the optical transmission to increase fault tolerance. Most commonly, this is done through the use of a spherical glass lenses embedded in the connector causing a non contact surface as opposed to the tradition ferrule to ferrule contact we see with traditional fiber optic connectors.
These connectors are typically IP68 rated when in the mated condition. This means they seal out not only dirt and other contaminants, but they are also completely submersible when mated. Stratos shows us how their HMA holds up to the abuse of extreme field use.
Expanded beam connectors are perfect for high and low temperatures, desserts, marine use, staging and lighting, broadcast and other mobile deployments, and where high volumes of mating cycles occur.
