Abstract
An optical add/drop apparatus and method wherein add/drop modules are designed into an optical add drop multiplexer such that channels are added/dropped without resorting to regeneration, with optical signals being routed into the add portion of the module which are not as dispersed as those optical signals being dropped, such that dispersion is compensated for while signal routing is facilitated.
