摘要： A network apparatus used in an optical network is disclosed. The network apparatus includes one or more first tunable and temperature controlled (TTC) lasers, one or more transmitters each of which is connected to one of said one or more TTC lasers, one or more second TTC lasers, one or more digital signal processing (DSP) transponders (TPNDs) each of which is connected to one of said one or more second TTC lasers, one or more receivers, and a controller to control said one or more transmitters and said one or more DSP TPNDs, wherein said one or more transmitters defragment an optical access spectrum, and said one or more DSP TPNDs exploit a newly available spectrum. Other apparatuses, systems, and methods also are disclosed.
