Abstract

A communications connection system includes a fiber optic adapter module configured to receive multiple fiber optic connectors. The fiber optic adapter module includes one or more media reading interfaces. Each media reading interface is configured to determine whether a fiber optic connector is received at one of the ports of the adapter module. Certain types of connectors store physical layer information. Certain types of media reading interfaces are configured to read the physical layer information from the connector if the connector stores such information.
