摘要： An interconnect fabric is constructed from a plurality of fixed wavelength transmitters which are used to transmit arriving data packets through a star coupler, and a plurality of tunable receivers which tune to whatever frequency necessary to receive the desired data from the star coupler. A control network, constructed from a plurality of fixed wavelength receivers and a plurality of tunable transmitters, determines what frequencies the tunable receivers should tune to, and sends a signal to effectuate such tuning.

摘要： The capacity of a multi-mode optical fiber system, such as a local area network, is increased by selectively propagating only higher-order modes through the multi-mode fiber. Because only a small number of higher-order modes are propagated, pulse spreading induced by modal dispersion is minimized, and the bandwidth of the multi-mode fiber is increased. Because of the reduced modal dispersion, higher-order modes are recovered from the multi-mode fiber in accordance with the invention without filtering the output of the fiber. This renders the system less vulnerable to mechanical perturbations that are known to reduce the bit error rate of systems requiring filtering. Thus, by propagating only higher-order modes in this manner, the "bandwidth-distance" product of the multi-mode fiber is significantly increased.
摘要翻译：通过选择性地仅通过多模光纤传播高阶模式，增加了诸如局域网的多模光纤系统的容量。由于只有少量的高阶模式被传播，所以通过模态色散引起的脉冲扩展被最小化，并且多模光纤的带宽增加。由于减少的模态色散，根据本发明从多模光纤中恢复高阶模式，而不过滤纤维的输出。这使得系统不太容易受到已知降低需要滤波的系统的误码率的机械扰动的影响。因此，通过以这种方式仅传播高阶模式，多模光纤的“带宽 - 距离”乘积显着增加。

摘要： The polarization-dependent distortion of an optical signal transmitted through an optical fiber is reduced by aligning the polarization of the optical signal to minimize the received signal distortion. A polarization controller (a device which can change the polarization of light in an optical fiber) may be located at either the input or output end of a long haul optical fiber system and is used to align the polarization of the signal to minimize the received signal distortion. Automatic operation of the polarization controller can be obtained by using a steepest-descent method based on a distortion measure of the received signal for the optical signal transmitted through the optical fiber to generate control signals which are used to control the polarization controller.
摘要翻译：通过对准光信号的偏振来减少通过光纤传输的光信号的偏振相关失真，以使接收信号失真最小化。偏振控制器（可以改变光纤中的光的偏振的装置）可以位于长距离光纤系统的输入端或输出端，并用于对齐信号的极化以最小化接收信号失真。可以通过使用基于通过光纤传输的光信号的接收信号的失真测量的最陡下降方法来获得偏振控制器的自动操作，以产生用于控制偏振控制器的控制信号。

摘要： A plurality of M receivers are utilized to receive a plurality of N channels from various incoming multiplexed data signals, N.gtoreq.M, where each incoming data signal arrives on a separate wavelength and comprises several channels. Each of the M receivers, in sequence, receives a separate one of the N channels, thereby M of the N channels. The process then repeats for the next M channels, in the same sequence as the first M channels. The repetitions continue until all N channels are received.
