摘要： An optical fiber protection switch that performs automatic protection switching. The optical fiber protection switch performs span and ring switching at the optical layer, thereby negating the need for SONET ADMs to perform the switching at the SONET layer. The optical fiber protection switch includes span switches and ring switches arranged to provide span and ring switching, respectively. The span switches and ring switches are implemented using 2×2 optical switches, for a total of eight 2×2 optical switches in the optical fiber protection switch. The system described herein may utilize SONET terminals and/or ATM switches in a WDM environment to support capacity increases while providing the ring and span switching functionality. A network switching element providing transparent, self-healing optical 4-fiber BLSR (OBLSR/4) is realized by using the optical fiber protection switch described herein.

摘要： A system for reducing the influence of polarization mode dispersion (PMD) in high speed fiber optical transmission channels. A signal is forward error correction (FEC) encoded according to an FEC code that defines a specified error tolerance per codeword. The invention then effectively randomizes the input polarization of the signal before transmission, in order to reduce the likelihood that PMD will distort one or more codewords beyond the allowed error tolerance. The invention will thereby increase the PMD-limited transmission distance in an optical transmission system.

摘要： An optical add/drop multiplexing unit (16, 116) includes a demultiplexer (53, 153) which optically isolates component signals of an optical input signal from an optical input terminal (22, 122). A plurality of switching units (61, 161) can optically couple either of two outputs to either of two inputs. One input of each switching unit receives a respective component signal from the demultiplexer, and the other is coupled to a respective protection input terminal (42, 142) of the multiplexing unit. One of the output terminals of each switching unit is coupled to a respective protection output terminal (43, 143), and the other is coupled to a respective input of a multiplexer (82, 182). The multiplexer has an output coupled to an optical output terminal (23, 123) of the multiplexing unit, and optically combines the signals at its inputs into an optical signal for its output. The multiplexing unit is operable to cause one of the component signals from the input signal to be routed to the further terminal, or to cause a component signal present at the further terminal to be included in the optical signal at the optical output terminal.

摘要： A technique for communicating a change in bit rates that dependent transponders should each transfer. In one implementation, an upstream transponder outputs a specific frequency communications signal to a downstream transponders. The downstream transponder reacts to receipt of the specific bit rate by requesting new bit rate window information. The upstream transponder communicates such new bit rate window. Thereafter both the upstream and downstream transponders transfer payloads of signals having bit rates within the programmed bit rate windows.
