    摘要： A method and system for transient and switching stabilization of a fiber optic transport system. One or more data-bearing channels are coupled to an optical fiber. The data-bearing channels are distributed among a plurality of frequency sub-bands. A set of control channels is also coupled to the optical fiber. Each control channel includes a pair of signals at separate frequencies. There is at least one control channel in each of the plurality of frequency sub-bands. The pair of signals of a control channel are cross-polarized. Optical power in at least one of the plurality of sub-bands is measured. Responsive to the measured optical power, the optical power of a control channel is adjusted to maintain a substantially constant power of a sub-band that contains the adjusted control channel.

    摘要： A system for enabling reconfiguration of a Wavelength Division Multiplexed (WDM) optical communications network. A plurality of channel transmitters are provided for generating respective optical signals within corresponding wavelength channels of the network. A broadband light source generates a broadband continuous wave light having a bandwidth corresponding to a channel band of the network. A wavelength selective switch includes a first switch port connected to receive optical signals from the channel transmitters. A second switch port is connected to receive the broadband continuous wave light from the broadband light source. The wavelength selective switch is configured to comb the broadband continuous wave light into a plurality of narrowband lights respectively corresponding with wavelength channels of the network. A common-OUT port of the wavelength selective switch outputs a WDM signal for transmission through a downstream fiber span of the network. The wavelength selective switch is controlled to switch optical signals from the first switch port to the common-OUT port as active wavelength channels, and further to switch narrowband lights corresponding to inactive channel wavelengths to the common-OUT port. Consequently, a spectral loading of the WDM signal is independent of the number of active wavelength channels.

    摘要： A modular bidirectional optical amplification system includes a multiwavelength dual amplifier building block, a multiwavelength unidirectional booster amplifier BB, a unidirectional and a bidirectional Optical Service Channel (OSC) BB, an Intelligent Optical Terminal Accessway (IOTA) module, and an interleaved filter BB. The dual amplifier BB is available in a C-band version, an E-band version and a hybrid version, and provides unidirectional or bidirectional multichannel amplification. The booster amplifier is available in a C-band version, an E-band version and in a booster plus variant; one for the C-band and one for E-band. The unidirectional and bidirectional OSC BBs provide a means for OAM&P functionality to the optical network. The IOTA BB provides multiplexing and demultiplexing, and the filter BB provides separation of the signal into grid-1 and grid-2 channels.
