Abstract

Radio frequency identification (RFID)-equipped communication components are disclosed. The communication components can include fiber optic components, such as fiber optic connectors and fiber optic adapters as examples. An RFID-equipped circuit is provided in the communication components to communicate information. In order that the electrical circuit be provided in the communication component without altering the communication component connection type, the circuit may be disposed in at least one recessed area of the communication component housing. In this manner, the communication component maintains its connection type such that it is compatible with a complementary communication component connection type for backwards compatibility while also being RFID-equipped. The circuit may also be provided in a substrate containing one or more electrical contacts coupled to the circuit such that a wired coupling is established with one or more electrical contacts provided in another communication component when connected.
