摘要： A method and apparatus is proposed for performing the ONU activation process in a PON having a standard line rate of 50 G or higher. The method and apparatus are based upon having the OLT instruct any activating ONUs to transmit at a line rate that is less than 50 G, which allows for an OLT receiver without any particular equalization configuration to accurately recover the upstream burst-mode transmissions from the activating ONUs. Once the activation process is completed, the OLT may instruct the new ONUs to reset their transmitters to operate at the higher line rate of the PON. Alternatively, at the end of the activation process, the new ONUs may be configured to automatically reset their transmitters to higher line rate.

摘要： A method of adding a transceiver including a transmitter and a receiver to an optical network. The transceiver is controlled to enable the receiver while maintaining the transmitter in a disabled state. The receiver detects a presence of an optical signal at a first wavelength. If an optical signal at the first wavelength is not present, the transmitter is enabled. Responsive to detection that an optical signal at the first wavelength is present: a feature of the optical signal, and a match condition between the detected feature and a predetermined feature are detected. The transmitter is enabled responsive to detection of the match condition.

摘要： Optical solutions to address and overcome the issues of superseding/replacing electrical interconnection networks have generally exploited some form of optical space switching. Such optical space switching architectures required multiple switching elements, leading to increased power consumption and footprint issues. Accordingly, it would be beneficial for new optical, e.g. fiber optic or integrated optical, interconnection architectures to address the traditional hierarchal time-division multiplexed (TDM) space based routing and interconnection to provide reduced latency, increased flexibility, lower cost, and lower power consumption. Accordingly, it would be beneficial to exploit networks operating in multiple domains by overlaying mode division multiplexing to provide increased throughput in bus, point-to-point networks, and multi-cast networks, for example, discretely or in combination with wavelength division multiplexing.

摘要： A disclosed optical transport system is configured to use hierarchical modulation for better utilization of the available BER margin, e.g., to increase data-transport capacity per carrier wavelength in the system. For example, hierarchical modulation may be used to reduce the number of carrier wavelengths assigned to support a given volume of bidirectional data transport between a set of nodes in an optical backbone network. An embodiment of the disclosed optical transport system can advantageously be constructed by modifying a conventional WDM system, e.g., by adding configurable hierarchical-layer mappers at some of the nodes and modifying some of the ROADMs used therein to enable a drop-and-continue mode of operation.

摘要： Provided is an optical network system and optical network unit (ONU) structure enabling a passive optical access network having a meshed structure with at least two central nodes and plurality of ONUs. One embodiment employs a partially or fully meshed structure of optical fibers between customer locations and multiple optical line terminal (OLT) locations creating a passive optical access network. The ONUs can communicate with a neighboring OLT or ONU using a symmetrical or asymmetrical TDM scheme, and convert between the different TDM schemes. For this purpose, the ONU structure includes two transceiver units, one connected to the western network port and the other to the eastern. The ONU can establish communication between either network port and a further ONU or an OLT, with the ONU controller adapted for passing through data, and converting TDM schemes.
