Abstract
An upgradeable electrical add/drop multiplexer is provided that is capable of processing light at numerous wavelengths thereby eliminating the need to add an optical add/drop multiplexer to an existing electrical add/drop multiplexer to process new services provided at different wavelengths than the wavelengths for which the existing electrical add/drop multiplexer are designed. The electrical add/drop multiplexer may be used to process light transmitted over a passive optical network under an RFoG, EPON, and/or 10GPON standard or any combination thereof or may be upgraded for future standards.
