Abstract: A method of channel balance for a channel balance section in an WDM optical network with a starting node, an ending node and a plurality of intermediate OADNs (Optical Add Drop Node) first determines express wavelengths and non-express wavelengths starting from the starting node, then calculates TX (transmitter) power change which will bring the express channel performance to a target value and sets TX power using obtained TX power value. The method then moves to non-express channels by calculating TX power change for each non-express channel and sets TX power using obtained TX power value. Lastly, for each intermediate OADN, the method calculates TX power change for each added channel in each OADN and sets TX power using obtained TX power value.

Abstract: A Re-Configurable Dispersion Compensation Module is provided. A new approach to the variable DCM, the RDCM combines existing optical switch technology with existing fixed DCM technology and advantageously also with existing TDCM technology into a programmable smart optical component. Advantageously Micro-Electrical Mechanical Switch (MEMS) optical switch technology may be used. The alternate RDCM technology provides a controller, and a set of controllable switches to employ a set of DCMs and TDCMs for adjusting the dispersion compensation along an optical signal path. This alternate RDCM technology mitigates the problems of conventional TDCMs, while fitting most of the requirements for high speed systems, and being of a compact size.

Abstract: An optical device simultaneously provides a multiplexing and demultiplexing function and combines dichroic WDM filter technology with Bragg grating filter technology. A plurality of adjacent sequential ports of a multi-port optical circulator serve as a vehicle for launching and receiving a multi-wavelength optical signal to be separated by the Bragg and dichroic filters. Other adjacent sequential ports having similar filters tuned to different wavelengths provide paths for combining the other wavelengths of light into a single signal. Conveniently a single circulating port serves as the input/output port of the device. The configuration can be applied an optical waveguide structure and, or more particularly to an optical fiber structure. Furthermore this configuration can combine multiplexing/demultiplexing function with a dispersion compensation function by adding a group of fiber Bragg gratings to a port of a circulator.
