Claim 18:
19. A passive optical system comprising:
an optical signal splitting device comprising:
an input port adapted to receive an optical signal;
a plurality of output ports adapted for connection to a plurality of passive optical network (PON), wherein an optical signal applied to the input port is divided into a plurality of separate optical signal segments, the plurality of separate optical signal segments applied to the plurality of PON segments via the plurality of output ports; and

a plurality of optical delay devices in optical communication with the plurality of output ports, wherein the plurality of optical delay devices provides a plurality of distinguishable delay values, that delay plurality of separate optical signal segments, the plurality of distinguishable delay values facilitating associations of the plurality of PON segments to the plurality of output ports based on optical time domain reflectometry (OTDR) measurements obtained via the input port.
