Abstract

A communications connection system includes a fiber optic connector including a storage device having memory configured to store physical layer information. The storage device also includes at least one contact member that is electrically connected to the memory. Certain types of fiber optic connectors have the storage device mounted to a key of the fiber optic connector. Certain types of fiber optic connectors have the storage device mounted in a cavity defined in the fiber optic connector.
