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 a WDM optical communication system that includes a plurality of nodes interconnected by communication links, a node is provided that includes a reconfigurable optical switch having a plurality of input ports and at least one output port. The node also includes a plurality of transmitters that are each coupled to one of the input ports of the optical switch.

At least one backup transmitter is coupled to one of the input ports of the optical switch. The backup transmitter includes a tunable laser tunable to any of the channel wavelengths at which the plurality of transmitters operate. The reconfigurable optical switch includes at least one wavelength selective element that selects at least one channel wavelength from among any of the channel wavelengths received at any of the input ports. The switch also includes a plurality of optical elements associated with the wavelength selective elements, Each of the optical elements direct one of the selected channel wavelengths selected by the associated wavelength selective element to the output port independently from every other channel wavelength. The selected channel wavelengths directed to the output port are combined on the output port.

摘要： The present invention significantly improves the signal to noise ratio (SNR) in a passive optical array by adding erbium-doped optical amplifiers between the sensor couplings to offset the coupler splitting losses. Optical amplifiers are inserted between the sensor couplings along the signal path, and the gain of the amplifiers is designed to offset losses due to the previous coupling. The overall SNR can be maintained without significant degradation even for large numbers of sensors. In a first aspect of the present invention, the amplifiers are located along the distribution and return buses directly after the couplers, except possibly for the last sensor. In a second aspect of the present invention, the amplifiers are located directly before the couplers. The optical amplifiers preferably are made of short lengths of erbium-doped fiber spliced into the distribution and return buses. Improvements can be made to the SNR when the distribution bus coupling ratios are set at optimal values. The value of the optimal coupling ratio depends upon the amplifier configuration, the excess loss and other configuration parameters. In alternative embodiments, sensors are grouped into parallel configurations along the distribution and return buses to increase the number of sensors without a corresponding increase in the number of amplifiers and with an improvement in system performance to a certain point.
摘要翻译： 本发明通过在传感器耦合之间添加掺铒光放大器来显着提高无源光学阵列中的信噪比（SNR），以抵消耦合器分离损耗。 光放大器被插入到沿着信号路径的传感器耦合之间，并且放大器的增益被设计成抵消由于先前的耦合引起的损耗。 即使对于大量的传感器也可以保持整体SNR而没有显着的降低。 在本发明的第一方面中，除了最后一个传感器之外，放大器沿着分配和返回总线直接位于耦合器之后。 在本发明的第二方面中，放大器直接位于耦合器之前。 光放大器优选地由拼接到分配和返回总线中的短长度的掺铒光纤制成。 当分配总线耦合比被设置为最佳值时，可以对SNR进行改进。 最佳耦合比的值取决于放大器配置，过剩损耗和其他配置参数。 在替代实施例中，传感器沿着分配和返回总线被分组成并行配置，以增加传感器的数量，而不会相应地增加放大器的数量，并且将系统性能提高到某一点。
