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.
