摘要： Disclosed herein is a bidirectional wavelength division multiplexed self-healing ring network. The ring network includes a central office and a plurality of remote nodes. Two optical fibers each connect the central office and the remote nodes in a ring form to allow optical signals to be bidirectionally received and transmitted between the central office and the remote nodes. One of the two optical fibers is a drop fiber for transmitting optical signals from the central office to the remote nodes, while the other is an add fiber for transmitting optical signals from the remote nodes to the central office.

摘要： A self-healing passive optical network is disclosed. The network includes a central office and a remote node connected to the central office through a main optical fiber. The remote node transmits one portion of power of the upstream optical signal, which has been input from each of the optical network units, to the central office, and returning a remaining portion of the power of the upstream optical signal to the optical network unit. The network also includes a plurality of optical network units connected to the remote node through a plurality of distribution optical fibers. Each of the optical network units transmits an upstream optical signal to the remote node through the directly connected distribution optical fiber, and detects abnormality occurrences from a state of the upstream optical signal returning from the remote node.

摘要： An encoding method includes selecting a run detection method in accordance with characteristics of image data, generating a run value by detecting a run that is repeated in the image data in accordance with the selected run detection method, generating run count bits by counting the number of repetitions of the detected run, and performing a run-length encoding using the detected run values and the run count bits. The run detection method includes a coefficient run detection method that detects a run based on pixel values, a pattern run detection method that detects the run based on whether the pixel blocks have a specified pattern, a difference run detection method that detects the run based on a difference value between two successive pixel values, and a residual run detection method that detects the run based on an error value that is a difference value between an actual pixel value and a predicted value.
