Abstract
An arrangement is provided for a configurable optical add/drop multiplexer (OADM) mechanism. The configurable OADM mechanism comprises at least one configurable optical add/drop multiplexer (C-OADM) module and at least one switch associated with the C-OADM modules (the minimum configuration is only one C-OADM with bypass (expansion) switches). The switches can be configured so that some of the C-OADM modules can be selected to form a processing pipeline. Each of the selected C-OADM moduels may be further configured to perform wavelength manipulations such as adding a wavelength, dropping a wavelength, tapping an input optical signal, and a combination thereof.
