Abstract

Aspects of the subject disclosure may include, for example, a device having an input port and multiple output ports adapted for connection to multiple passive optical network (PON) segments. The device includes an optical power splitting device in communication between the input port and the multiple output ports and adapted to provide divided portions of an optical signal received at the input port to the PON segments via the output ports. The device includes optical delay devices in optical communication between the optical power splitting device and at least a portion of the multiple output ports. The optical delay devices provide distinguishable delay values, that delay the divided portions of the optical signal, the distinguishable delay values facilitating associations of the PON segments to the output ports based on optical time domain reflectometry (OTDR) measurements obtained via the input port. Other embodiments are disclosed.
