Abstract: A communications network has a plurality of nodes interconnected by an optical transmission medium. The transmission medium is capable of a carrying a plurality of wavelengths organized into bands. A filter at each node for drops a band associated therewith and passively forwards other bands through the transmission medium. A device is provided at each node for adding a band to the transmission medium. Communication can be established directly between a pair of nodes in the network sharing a common band without the active intervention of any intervening node. This allows the network to be protocol independent. Also, the low losses incurred by the passive filters permit relatively long path lengths without optical amplification.

Abstract: A bank of complex gain elements is used to provide a step-wise approximation of an arbitrary complex-gain predistortion function for a nonlinear transmitter. The bank of gain elements is in an adaptive loop realizing adaptive control. The adaptive loop is closed between an Input of the gain bank and an output of the transmitter through a linear receiver at an adaptive controller composed of a bank of proportional-integral (PI) controllers. The real and imaginary parts of each predistortion gain element are controlled by a corresponding adaptive PI controller. The signals processed by the adaptive controller are represented in orthogonal coordinates in terms of real and imaginary number pairs of complex numbers. The adaptive controller achieves unconditionally stable operation independently from the arbitrary phase rotation in the input signal or the adaptive loop.

Abstract: An adaptive controller for linearization of transmitters using predistortion of the input signal has reduced sensitivity to impairments such as gain variation, phase noise or modulation/demodulation frequency instability by linearizing an adaptively normalized gain provided through a separate estimation and cancellation of linear gain variations. Values of a nonlinear and a linear gain blocks, cascaded with the linearized transmitter and called respectively a predistortion block and a gain regulation block, are independently adjusted by two different adaptive controllers. In one embodiment, four banks of real gain elements compose the predistortion block and realize an arbitrary step-wise approximation of a generalized 2null2 transmit gain matrix of nonlinear functions. In a further embodiment cancellation of a DC level bias multi-channel impairment is provided by an adaptively adjusted signal adder inserted in the transmit chain between the predistortion block and the linearized transmitter.

Abstract: A flow of information over a network is controlled by a policing function placed at a data link layer of the network. For a full-duplex architecture, an accumulated count value for each packet of information received as input by a switching device is ascertained during a predetermined interval. The policing function at a data link layer determines if the accumulated count value has exceeded an interval bit rate based on a transmission rate set by a traffic contract at a networking layer higher than the data link layer. In response to the accumulated count value exceeding the interval bit rate, the switching device sends a PAUSE frame to halt transmission of the information. The half-duplex architecture, collision based backpressure and carrier-sense backpressure techniques are used by the policing function for enforcement of the traffic contracts.
