    摘要： A reconfigurable WDM add/drop multiplexer and its method of operation at an add/drop node on an optical fiber carrying a plurality of WDM signals is described. The WDM add/drop multiplexer has a coupler and a demultiplexer element dropping WDM signals from the optical fiber to a plurality of drop terminals, and a wavelength-selective switch adding WDM signals from a plurality of add terminals onto the optical fiber. The coupler splits the WDM signals received from the optical fiber and passes the split WDM signals to the first and second output terminals. The demultiplexer element separates the split WDM signals at the plurality of drop terminals. The wavelength-selective switch, which has an input terminal for connection to the second coupler output terminal and an output terminal for connection to the optical fiber, selectively adds WDM signals on the plurality of add terminals to the optical fiber responsive to control signals.

    摘要： An optical transmission system and method for reducing non-linear distortion caused by the interaction of Self-Phase Modulation and Group Velocity Dispersion is disclosed. An optical link includes a transmitter for providing signals at a first optical wavelength, a transponder for converting the first optical wavelength to a second optical wavelength, a plurality of spans of optical transmission fiber and optical fiber amplifiers, a dispersion compensating device, and a receiver. The system operates at a relatively high input power level. The transponder includes a device for smoothing edges of the rise and fall times of optical pulses, such as an electrical attenuator and low pass filter, so that sharp-edged pulses received from the transmitter are transformed to a Gaussian shape. A dispersion compensating device, such as an optical fiber grating, also helps to improve the bit error rate as a function of receiver sensitivity despite an overall link length less than 600 km.

    摘要： Systems and methods for verifying performance at an intermediate point in an optical link are provided by virtue of one embodiment of the present invention. One application is locating a fault along a long optical link while minimizing the need for trained personnel to inspect and monitor the link at numerous widely separated locations. At an intermediate point in the link, a portion of the optical signal present is tapped off and demodulated. By use of error correction decoding techniques on the demodulated data, the performance of the link up until that intermediate point may be verified.
