Abstract:
1. A method of mapping a position of an end of a specific customer fiber on a passive optical network (PON), comprising steps of: connecting an optical reflector to an end of a specific customer fiber; carrying out an optical time domain reflectometer (OTDR) trace of the PON utilising an OTDR device located at a central office; identifying a target reflection event in the OTDR trace having an increased amplitude relative to other reflection events in the OTDR trace; mapping data associated with the target reflection event to a specific customer; and determining whether said identified target reflection event on the OTDR trace conflicts with other reflection events associated with other customer optical network terminations (ONTs), and if so, performing additional steps of: identifying an area of the OTDR trace free from potentially conflicting reflection events; and calculating length of optical fiber required to be spliced to said specific customer fiber in order to shift said target reflection event to said area of the OTDR trace.
