摘要： Optical networks may store information or data therein by maintaining the information or data in motion. The optical networks may include optical fiber rings configured to receive optical signals comprising the information or data and to circulate the optical signals within the optical fiber rings. The optical signals and the information or data may be transferred out of the optical fiber rings in order to amplify the optical signals (e.g., to overcome losses due to attenuation within the optical fiber rings), to analyze the optical signals according to one or more processing techniques, or to transfer the information or data to another computer device upon request. If continued storage of the information or data is required, an optical signal including the information or data may be transferred back into the optical fiber rings and may continue to circulate therein.

摘要： A method for primary and backup links protection in passive optical network (PON) and a ring-based system are disclosed. The method includes establishing ring-based PON between at least two optical line terminals OLT through at least two user side edge nodes or network side edge nodes, each of the OLTs connecting with any other OLT through at least two edge nodes. In the ring-based PON, existing two links clockwise and counterclockwise, any one of them is a primary link and the other is a backup link. When the primary link is normal, any node in the ring-based PON receives data by the primary link; when the primary link is failed, the failure will be informed to relative nodes in the ring-based PON, and any node in the ring-based PON receives data by the backup link. According to the embodiments of this invention, the effect to network caused by single link failure in PON network can be reduced.

摘要： The invention relates to a local network with several subscribers that are interconnected by an optical data line (1) for transmitting audio and/or video data and that are connected to a ring network by control data. At least one subscriber of the local network is configured as a data source (2) for compressed audio and video data, for example as a DVD player. At least one subscriber represents a data think (3) for audio data and at least one subscriber (4) represents a data think for transmitted video data.

The decoded, separate audio data and/or the video data are transmitted to their data thinks (4, 3) by the optical data line (1) and to the output units (9, 11) that are allocated to said data thinks. The inventive configuration or a local network is very economical and makes very efficient use of the transmission capacity of a network.

摘要： A plurality of optical cross-connect switches (OCCS B, OCCS C, OCCS D) are freely interconnected (302, 304, 306, 308, 310, 312) to form a mesh type network (202). At least three of the optical cross-connect switches are switched to form a line-switched ring network, thereby forming a ring/mesh network (202). Simply by changing the switching logic of the optical cross-connect swithes within the ring/mesh network, new rings can be created and existing rings can be modified, thereby providing a great deal of flexibility to make changes to the network as traffic patterns change without incurring hardware costs or significant network downtime. Another advantage of the ring/mesh design approach is that spare capacity within the line-switched ring can be utilized by the mesh network, and spare capacity within the mesh network can be utilized by the line-switched ring, thereby significantly increasing the spare efficiency.
摘要翻译：多个光交叉连接交换机（OCCS B，OCCS C，OCCS D）自由互连（302,304,306,308,310,312）以形成网状网络（202）。至少三个光交叉连接交换机被切换以形成线路交换环网，由此形成环/网状网络（202）。通过改变环/网状网络内的光交叉连接交换机的交换逻辑，可以创建新的环，并修改现有的环，从而提供很大的灵活性，因为业务模式发生变化导致硬件成本或重大网络停机时间。环/网设计方法的另一个优点是网络网络可以利用线路交换环内的备用容量，网线网络中的备用容量可以被线路交换环使用，从而显着提高备用效率。
