Claim 0:
1. A multiport optical device, comprising:
an input port;
a plurality of output ports adapted for connection to a plurality of passive optical network (PON) segments;
an optical power splitting device in communication between the input port and the plurality of output ports and adapted to provide divided portions of an optical signal received at the input port to the plurality of PON segments via the plurality of output ports; and
a plurality of optical delay devices in optical communication between the optical power splitting device and at least a portion of the plurality of output ports, wherein the plurality of optical delay devices provide a plurality of distinguishable delay values, that delay the divided portions of the optical signal, 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.
