Abstract
Techniques are described for obtaining, by an optical network device (OND) coupled to an optical network, physical layer data of the optical network; generating, by the OND, an encapsulated representation of the physical layer data of the optical network; and outputting the encapsulated representation of the physical layer data to a diagnostic device.
Claims20
A method comprising:
- receiving, by an optical line terminal (OLT) coupled to a passive optical network, an optical signal that represents an upstream frame of the passive optical network;
- capturing, by the OLT and while receiving the optical signal that represents the upstream frame, a representation of physical layer data corresponding to the upstream frame of the passive optical network, wherein the representation of the physical layer data comprises samples of the optical signal;
- generating, by the OLT, an encapsulated representation of the physical layer data corresponding to the upstream frame of the passive optical network;
- and
- outputting, via another network different than the passive optical network, the encapsulated representation of the physical layer data to another device different than the OLT.
An optical line terminal (OLT) coupled to a passive optical network, wherein the OLT comprises:
- an optical detector configured to receive an optical signal that represents an upstream frame of the passive optical network;
- a memory;
- and
- one or more processors configured to:
- obtain, via the optical detector, a representation of physical layer data of the passive optical network corresponding to the upstream frame of the passive optical network, wherein the representation of the physical layer data comprises samples of the optical signal;
- generate an encapsulated representation of the physical layer data of the passive optical network;
- and
- output, via another network different than the passive optical network, the encapsulated representation of the physical layer data to an external device.
An optical line terminal (OLT) coupled to a passive optical network, wherein the OLT comprises:
- means for receiving an optical signal that represents an upstream frame of the passive optical network;
- means for obtaining a representation of physical layer data of the passive optical network corresponding to the upstream frame of the passive optical network, wherein the representation of the physical layer data comprises samples of the optical signal;
- means for generating an encapsulated representation of the physical layer data of the passive optical network;
- and
- means for outputting, via another network different than the passive optical network, the encapsulated representation of the physical layer data to an external device.
A non-transitory computer-readable storage medium storing instructions that, when executed, cause one or more processors of an optical line terminal (OLT) coupled to a passive optical network to:
- obtain a representation of physical layer data of the passive optical network corresponding to an upstream frame of the passive optical network, wherein the representation of the physical laver data comprises samples of an optical signal that corresponds to the upstream frame;
- generate an encapsulated representation of the physical layer data of the passive optical network;
- and
- output, via another network, the encapsulated representation of the physical layer data to an external device.
