Abstract
An electronic apparatus includes: a housing with a signal entrance; an optical fiber with a first end and a second end adjacent the signal entrance; a remote control signal receiver and an indicator light emitter in the housing and adjacent the first end, the indicator light emitter emitting an indicator light signal towards the first end; a light receiver in the housing, adjacent the first end and configured to receive the indicator light signal, which is emitted from the indicator light emitter and reflected back by a barrier at the signal entrance and process the reflected indicator light signal, thereby outputting an electrical signal, the reflected indicator light signal being transmitted back to the first end through the optical fiber and then received by the light receiver; and a signal processing circuit electrically coupled with the light receiver and configured to process the electrical signal, thereby obtaining a control signal.
