OZ Optics produces fiber optic patchcords specifically for high power applications. These patchcords feature special high power fibers, carefully prepared fiber endfaces, and specially designed fiber optic connectors to ensure maximum power handling for your application. This specialty termination requires more diligent handling methods such as cleanliness, and low power testing. When not in use, the ends of the fiber and the connector receptacles should be covered with the supplied metal caps. This will protect the connectors from dirt and contamination.
