摘要： In a WDM optical communication system that includes a plurality of nodes interconnected by communication links, a node is provided that includes a first plurality of transponders each generating and/or receiving an information-bearing optical signal at a different channel wavelength from one another. An optical coupling arrangement, which may include one or more reconfigurable optical switches, transfers the channel wavelengths between a link connected to the node and the first plurality of transponders. The arrangement is adaptable to reconfigure its operational state to selectively direct different ones of the channel wavelengths from the link to different ones of the transponders without disturbing the optical path through the node traversed by any other channel wavelengths. A communications and configuration arrangement is provided, which transfers data identifying the respective channel wavelengths at which the transponders operate from the transponders to the optical coupling arrangement. In response to the transferred data, the communications and configuration arrangement reconfigures the operational state of the optical coupling arrangement.

摘要： In accordance with the invention a multiwavelength optical fiber cross connect is provided with an active all-fiber optical router for multiplexing/demultiplexing. The router is comprised of one electronic component--a phase controller--and four fiber components: 1) a fiber directional coupler, 2) a fiber reflective grating filter, 3) a fiber tap, and 4) a fiber phase modulator. The application describes how to make optical routers from these components ranging in complexity from a single wavelength drop router to an N-port, N-wavelength router for add/drop multiplexing. The application also describes how optical wavelength routers can be combined to create optical fiber Cross connect (OXCs), ranging in complexity from 2.times.2 single wavelength OXCs to NXN, M-wavelength OXCs.

摘要： A method and apparatus is provided for reducing impairment to an adiabatically chirped optical signal propagating in an optical communication system. The method begins by receiving an adiabatically chirped optical signal that has traversed one or more network components in the optical communication system. The optical signal has a parameter characteristic of signal quality (e.g., an extinction ratio) that is reduced at least in part by a fidelity-degrading transmission slope accumulated in the one or more network components. A fidelity-enhancing transmission slope imparted to at least one wavelength of the adiabatically chirped optical signal at one or more select points along a transmission path of the communication system so that the optical signal experiences an increase in said parameter characteristic of signal quality.

摘要： A variable dispersion optical unit is used to vary the relative dispersion between an input signal and an output signal of the optical unit under control of a control circuit. The control unit uses an optical homodyne detector to beat the input optical signal with the output optical signal to generate a control signal to adjust the relative dispersion a variable dispersive element. The variable dispersive optical element may be selected from a group of dispersive elements including at least a Bragg grating, a Fabry-Perot filter, a Mach-Zehnder filter, and a waveguide routing element. The variable dispersive optical unit can be used as part of a variable wavelength selective optical circuit (e.g., a tunable wavelength filter) where the varying dispersion characteristics is used to control the selection of the wavelength of the tunable wavelength filter, or is used to select the drop/add wavelength(s) of an Add/Drop circuit.

摘要： A Raman amplified transmission includes at least two pump sources to provide amplification to optical signals residing in the C-band (1530-1562 nm) and L-band (1574-1604 nm). The pump signals are chosen so as to provide for a relatively flat and wide composite gain spectrum with a width at least 50% greater than that generated by a monochromatic pump, while also chosen so as to prevent any four-wave mixing products from being in either the C- or L-bands.
