CONFIGURABLE OPTICAL ADD/DROP MULTIPLEXER WITH PARTIAL OR COMPLETE WAVELENGTH DROP CAPABILITY

摘要

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 modules 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.
