摘要： Methods and systems for analyzing optical parameters of a selected optical fiber member are disclosed. A signal input from an optical fiber member may be selected by instructing a corresponding optical separation device. The output from the corresponding optical separation device may be combined with the outputs of other optical separation devices using an optical coupler. A measurement circuit may measure the optical parameter from the output. Proper operation of an optical separation device may be validated by a monitoring circuit. The monitoring circuit may provide an indication to a user or may be processed by a diagnostic processor. A processing circuit may select one of the optical separation devices in order to measure the optical parameter for a corresponding optical fiber member and consequently may instruct an adjustment circuit to cause the selected optical fiber member to conform to a desired value of the optical ameter.

摘要： A network arrangement where traffic elements of network nodes are programmable. A traffic element comprises electrically controllable transceiver pool having one or more ports that are coupled to an electrically controllable optical director that has all-optical information communication paths. The transceiver pool has one or more customer connection points in addition to the one or more connection points that connect to the optical director, and is adapted to couple a signal from any of the customer connection points to the optical director, at a particular wavelength. The choices for the specific coupling within the optical director and of the wavelengths are specified by control signals that are applied to the transceiver pool and to the optical director.

A signal input from an optical fiber member is selected by instructing a corresponding optical separation device. The output from the corresponding optical separation device is combined with the outputs of other optical separation devices using an optical coupler. A common measurement circuit measures the optical parameter from the output. Proper operation of an optical separation device is validated by a monitoring circuit.

摘要： This is a method for use in architecting low cost networks using a thin optical transport layer. A long reach hot pluggable interface is inserted onto an electrical switch resulting in a standardization of the optical layer. Standardized parts like the long reach hot pluggable interfaces and standard control planes form the logic that connects components of the low cost optical layer. After the components are in place, provisioning is done at end points only. This ensures an automatic and fast turn-up capacity without the need to visit intermediate sites in the network.

摘要： Methods and apparatus to manage bypass paths in an Internet protocol (IP) network are disclosed. An example method disclosed herein includes receiving IP traffic at an aggregation router and measuring a bandwidth value of the IP traffic forwarded from the aggregation router to an IP router at a starting node. The example method also includes establishing a first non-routed bypass path between a switch at the starting node and a first switch at a first destination node when a measured traffic throughput value of the IP router at the starting node exceeds a first threshold value, and sending the IP traffic from the aggregation router via the bypass path.

摘要： A system and method for simultaneous delivery of a plurality of independent blocks of 500 MHz digital broadcast television services, stacking a plurality of RF blocks on a plurality of spectrally sliced WDM optical bands. The method for delivering a plurality of video blocks to a user terminal serviced by a remote node comprises the steps of receiving, by a first WDM, a broadband signal from a broadband signal source, separating, by the first WDM, the broadband signal into a plurality of optical hands, modulating each of the plurality of optical bands with a composite signal representing data in a plurality of independent RF blocks to form a plurality of modulated signals, forwarding the plurality of modulated signals to a second WDM to form a combined broadcast signal, transmitting the combined broadcast signal over feeder fiber to a remote node, selecting a RF block for distribution over a distribution fiber to a conventional satellite set-top box at a user's site and forwarding the selected RF block to the user's site. A novel method and system for reducing spontaneous beat noise is also described.
