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.

Abstract: A method for validating service continuity of deployed fiber serving terminals in a passive optical network includes broadcasting, from a central office of a passive optical network, a beacon signal to a plurality of beacon responders, wherein each beacon responder of the plurality of beacon responders is connected to a respective fiber serving terminal of a plurality of fiber serving terminals of the passive optical network, changing a counter in response to each response message that is received from the plurality of beacon responders in response to the beacon signal, and generating a report indicating which fiber serving terminals of the plurality of fiber serving terminals are functioning properly and which fiber serving terminals of the plurality of fiber serving terminals are not functioning properly, based on whether a count of the counter is equal to an expected number of responses, after an expiration of a predefined period of time.

Abstract: An example apparatus may include an optical splitter apparatus that includes a dual mode fiber having a single mode fiber core embedded in a multi-mode fiber core, a plurality of single mode fibers, and a funnel waveguide coupling the dual mode fiber to the single mode fibers. The optical splitter apparatus may be for use in a passive optical network. The single mode fiber core may be for transmitting downstream optical signals, where the funnel waveguide distributes the downstream optical signals to the single mode fibers. In addition, the single mode fibers may transmit upstream optical signals, and the funnel waveguide may direct the upstream optical signals into the multi-mode fiber core. The optical splitter apparatus may have an asymmetric insertion loss ratio between the downstream optical signals received via the single mode fiber core and the upstream optical signals received via the single mode fibers.
