Hybrid AM-VSB/256-QAM/Internet transport systems in the campus

We propose and demonstrate simultaneous transport of 1556 nm downstream CATV analog video, 256-quadrature amplitude modulation (QAM) digital TV and Internet access signals, as well as 1310 nm upstream Internet access signals over the existing multimode fiber (MMF) in the campus. This technique makes...

Description
Summary:We propose and demonstrate simultaneous transport of 1556 nm downstream CATV analog video, 256-quadrature amplitude modulation (QAM) digital TV and Internet access signals, as well as 1310 nm upstream Internet access signals over the existing multimode fiber (MMF) in the campus. This technique makes possible analog and digital video transmission, gigabit Ethernet as well as Internet access to the classrooms through the existing MMF. Our proposed system has the distinctive advantages of simplicity and lower cost, and is thus eminently suitable for fiber to the classrooms application.
