摘要： This disclosure relates to detection of optical fiber failure and implementation of protection switching in a passive optical network (PON). A protection switch determines whether there is an optical fiber failure in a fiber link between an OLT and a group of ONTs. In the case of an optical fiber failure, an optical fiber may be physically cut or damaged, causing the optical fiber link to be disabled. A protection switch may detect an optical fiber failure by determining a peak optical power of at least a portion of an upstream optical signal transmitted from one or more ONTs via the optical fiber link. If the peak optical power is less than a threshold value, the protection switch may detect a fiber failure. In response to a detected fiber failure, the protection switch may switch upstream and downstream PON transmissions from a primary optical fiber to a secondary optical fiber.

摘要： This disclosure describes techniques for providing a communication path for upstream communications originating from a node of an optical network. In particular, methods and devices are described for combining upstream communications originating from the node of the optical network with upstream communications originating from subscriber devices coupled to the node. The upstream communication originating from the node may, for example, include status information about the node. The upstream communication, which may include status information about the node, essentially piggy-backs onto upstream communication originating from the subscriber devices coupled to the node.

摘要： This disclosure describes ONT-based management of micronodes in an RFOG network. A micronode is configured to permit remote management via an ONT in an optical network. An optical networking protocol, such as a PON protocol, may be used to exchange information with an ONT for management of the micronode. Management may include configuration and monitoring of the micronode. The micronode may have a management interface that supports remote configuration and monitoring via an ONT coupled to the management interface. An operator may use the ONT as a management terminal for the micronode. The ONT may permit an operator to effectively manage micronodes, and also may offer a ready upgrade path to provide optical networking services such as PON services to a subscriber when the operator is ready to upgrade its CO equipment and CPE.

摘要： This disclosure is directed to techniques for facilitating return path compliance in networks. A device, such as an optical network terminal (ONT), may, for example, buffer a digital representation of an upstream analog signal to facilitate return path compliance specified by a Data Over Cable Service Interface Specification (DOCSIS) 3.0 standard. The ONT may comprise a first conversion module that converts an upstream analog signal into a corresponding digital signal and a signal detection module that determines whether the upstream analog signal represents a valid upstream communication. The device may further comprise a buffer that buffers the corresponding digital signal while the signal detection module makes the determination, a second conversion module that converts the buffered digital signal into a reconverted upstream analog signal upon the determination that the upstream analog signal is valid and a laser that transmits the reconverted upstream analog signal via a fiber optical cable.

摘要： In general, this disclosure relates to optical network devices with support for multiple physical layer transport standards. An optical network device may include an optical receiver that can be adaptively configured to support different physical layer transport standards. For example, the optical receiver may include a photodiode and a control unit to adjust a characteristic of the photodiode to support different optical physical layer transport standards on an adaptive basis. For example, the control unit may adjust the photodiode characteristic to prevent an overload condition when an optical signal is received according to the physical layer access standard.

摘要： In general, techniques are described for monitoring downstream traffic in order to schedule delivery of upstream traffic in a computer network. The techniques may be implemented by an optical line terminal (OLT) comprising a control unit and an interface. The control unit determines an amount of upstream data that is waiting at one of a plurality of ONTs to be transmitted upstream to the OLT, and determines an amount of downstream data that is transmitted by the OLT to this ONT. The control unit increases the determined amount of upstream data based on the determined amount of downstream data transmitted by the OLT to the ONTs and, after increasing the determined amount of upstream data, generates an upstream grant map that grants time slots to the ONTs based on the determined amount of upstream data. The interface transmits the upstream grant map downstream to the ONTs.
