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.
