Abstract: A method is provided for mapping the position of a customer fiber end on a passive optical network (PON). The method comprises the steps of: connecting an optical reflector to a specific customer fiber end; carrying out an optical time domain reflectometer (OTDR) trace of the a passive optical network utilising a central office OTDR device; identifying a target reflection event in the OTDR trace having an increased amplitude relative to other reflection events in the OTDR trace, consequent upon the presence of the optical reflector; and mapping data associated with the target reflection event to the specific customer.

Abstract: This disclosure provides a remote control for an electronic display apparatus, includes an operation panel disposed on a surface of the remote control, and a circuit board located inside the remote control. The circuit board includes a control module and a signal emitting module. The operation panel includes a key group. The key group includes an enter key, an inner ring direction key, and an outer ring direction key. The control module is connected to the key group for recognizing different press operations. If the press operation is on the inner ring direction key, a signal for moving a cursor displayed on a display device of the electronic display apparatus one item is emitted through the signal emitting module. If the press operation is on the outer ring direction key, a signal for moving a cursor displayed on the display device of the electronic display apparatus at least two items is emitted through the signal emitting module.
