Abstract: A method and apparatus are provided for high signal-to-noise ratio (SNR) optical subcarrier management and reception in a communication network. In a multiple-wavelength optical communications link, ancillary signals that are conveyed by low-level intensity-modulated subcarriers are received with increased sensitivity in the subcarrier channel of the network. An increased SNR is accomplished by passing the same ancillary signal along all the carriers and by combining the received signals at a summing amplifier in the electrical domain.

Abstract: A polarization mode compensation system and method using optical switch elements to establish incremental delays between different polarization modes of an optical data signal is provided. A polarization mode separator separates the optical data signal into first and second orthogonally polarized optical signals. A first variable switching delay element provides a first incremental propagation delay for the first polarized optical signal. A second variable switching delay element provides a second incremental propagation delay for the second polarized optical signal. The first and second variable switching delay elements consist of a series of optical switches optically interconnected by different incremental lengths of optical fiber. For example, 2.times.2 optical switches are provided for switching between a reference fiber segment and a respective delay fiber segment to provide a relative incremental propagation delay. A controller controls optical switches in the first and second variable switching delay elements to set first and second incremental propagation delays. In particular, the first and second polarized optical signals are incrementally delayed relative to one another so as to compensate for polarization mode dispersion. A beam combiner then combines the first and second polarized optical signals to form an optical output data signal which can be detected accurately by a receiver without the effects of polarization mode dispersion. In this way, optical data signals can be reliably transmitted over greater distances along a long-haul fiber optic dispersive medium at even greater bit-rates and bandwidth.

Abstract: A system and method for photonic facility and line protection switching in an optical network to permit fault tolerant operation. The optical network comprises components whose operation is monitored by a controller. If the controller determines an optical transmission line in a signal path has failed, the controller will re-route the signal path through a spare, or protect component. Alternatively, the controller can re-route the signal path through a frequency translator and another optical transmission line.

Abstract: A method is provided for predicting an installed performance parameter of an optical fiber cable. The method includes obtaining a measurement indicative of a value of the performance parameter at a first moment in time. A measurement indicative of a value of the performance parameter at a second moment in time may then be obtained.

Abstract: A bidirectional optical link has a plurality of wavelengths to carry information in first and second differing transmission directions to optimize system performance. First and second sets of wavelengths of the plurality of wavelengths are determined wherein the wavelengths of the first set alternate with the wavelengths of the second set. Transmitting is performed in the first transmission direction by way of the first set of wavelengths and in the second transmission direction by way of the second set of wavelengths whereby the transmission directions of adjacent wavelengths of the plurality of wavelengths differ. The wavelengths of the plurality of wavelengths are wavelength division multiplexed within the optical link and the wavelengths transmitted in the same direction are multiplexed with each other. The wavelengths of the plurality of wavelengths can be substantially evenly spaced apart from each other or adjacent wavelengths transmitted in different directions may overlap. The wavelengths of the first set of wavelengths and the wavelengths of the second set of wavelengths are transmitted by way of a single optical fiber. The single optical fiber is provided with a bidirectional amplifier. Selected wavelengths of the plurality of wavelengths can be moved during the transmitting of the plurality of wavelengths in order to avoid interference.

Abstract: A system, method and apparatus are described that allow for the updating and transmittal of a low data rate signal providing ancillary network data as a rider on a high data rate optical signal. This subcarrier modulated signal can be processed and updated by using a drop/insert facility without having to alter the high data rate signal component of the data signal. Since the subcarrier signal can be detected by inexpensive equipment without having to detect and demultiplex the high data rate signal, the approach described offers a cost effective solution to the problem of network monitoring. Ancillary network management information can be communicated regardless of the quality or loss of the high data rate signal. In addition, by updating the subcarrier signal rider in a cumulative manner, a complete history of the fiber link the modulated optical signal travels on is provided to network management.
