Class LightPath

java.lang.Object
ons.LightPath
Direct Known Subclasses:
EONLightPath, WDMLightPath
public abstract class LightPath
extends java.lang.Object
In an optical network, a lightpath is a clear optical path which may traverse several links in the network. It is also good to know that information transmitted through lightpaths does not undergo any conversion to or from electrical form.
