Title:
DISPERSION COMPENSATION FOR HIGH SPEED OPTICAL TRANSMISSION SYSTEMS
Document Type and Number:
WIPO Patent Application WO2002015441
Kind Code:
A3
Abstract:
A tuneable dispersion compensation module may be used to determine a desired dispersion compensation value for a transmission path. In one aspect, the tunable dispersion compensation module comprises at least one variable coupler that is capable of receiving one or more optical signals and providing the signals to a first path having a first dispersion, or second path having a second dispersion. Once the desired value is determined, a connectable compensation module is configured to provide the optimal dispersion compensation value determined using the tuneable module. The connectable module may include a reconfigurable connector that is capable of receiving one or more optical signals and providing the signals to a first path having a first dispersion and a second path having a second dispersion. As is the case with the tuneable module, multiple stages can be provided to the connectable module to achieve desired range and/or granularity of dispersion.
