摘要： An optical line terminal is operable in a passive optical network. The optical line terminal includes a chassis. A plurality of optical subsystems are disposed within the chassis. Each optical subsystem is operable to generate optical signals for delivery to a port. Each optical subsystem includes one or more optical switches. When a fault condition is detected at a first optical subsystem preventing the delivery of first optical signals generated by the first optical subsystem to the port of the first optical subsystem, the optical switches switch to deliver second downstream optical signals generated by a second optical subsystem to the port of the first optical subsystem.

摘要： A system for performing failover switches in an optical network, such as a time and wavelength division passive optical networks (TWDM PON) like NG-PON2, includes a backup optical line terminal (OLT) for backing up communications of a primary OLT. The backup OLT is configured to allocate small upstream time slots, referred to herein as “de minimis” time slots, to at least one optical network terminal (ONT) communicating with the primary OLT during normal operation. When a failure occurs that prevents communication between the ONT and the primary OLT, the ONT autonomously tunes to the upstream and downstream wavelength pairs of the backup OLT and begins to transmit data to the backup OLT in the de minimis time slot allocated to it. The presence of data in the de minimis time slot indicates the occurrence of a failover switch to the backup OLT, and the backup OLT then begins to allocate time slots to this ONT, which is normally serviced by the primary OLT according to its normal TDM algorithm.

摘要： The present document provides a method and apparatus for processing abnormal uplink data, herein, the method includes: a first time wavelength division multiplexing TWDM channel terminal in a TWDM passive optical network PON detecting abnormal uplink data; the first TWDM channel terminal sending uplink data abnormality information to other TWDM channel terminals in the TWDM PON, herein the uplink data abnormality information is used for the other TWDM channel terminals detecting whether uplink data sent by an optical network unit ONU managed by the other TWDM channel terminals are abnormal, and processing the ONU sending the abnormal uplink data when the abnormality is detected, solves the problem that an ONU sends data on a wrong uplink wavelength channel to cause uplink data interference on the uplink wavelength channel, and further achieves the effect of rapidly locating the ONU using the wrong uplink wavelength for communication.

摘要： In some embodiments, an apparatus includes a switch device that can be operatively coupled to a network having a set of links. The switch device can receive at a first time, a message having a set of physical coding sublayer (PCS) lanes. The message can include an error notification within a first subset of PCS lanes from the set of PCS lanes and not within a second subset of PCS lanes from the set of PCS lanes. The error notification is associated with signal degradation of a link from the set of links, where the switch device can send a first signal in response to receiving the message at the first time. The switch device can also receive at a second time a message without the error notification, and the switch device can send a second signal in response to receiving the message at the second time.

摘要： A network management system manages preplanned alternative paths in a wavelength switched optical network for a traffic flow having a working path and two or more preplanned alternative paths from a source node to a destination node. A processing part determines if, after the fault, a number of available alternative paths for the respective traffic flow drops to a threshold. If so, a new alternative path is calculated and set up the new alternative path in the nodes, to enable one or more of the nodes to move the traffic flow onto the new alternative path in the event of further faults without waiting for input from the network management system. Thus multiple faults can be handled without the nodes needing to store details of so many such alternative paths. Otherwise, many such alternative paths are needed to take account of many different possible failure locations.
