As LED applications with fast dimming appears, it is required that the variable pulse position modulation (VPPM)-based visible light communications (VLC) scheme works in this environment also. With the previous VPPM scheme, however, transmission was

A code-division multiple-access (CDMA) passive optical network is proposed as an optical access network system to satisfy the subscriber's increasing data traffic. A CDMA scheme is used not only for delivering multiple channels to as many remote unit

An optics layer protection method for the Gigabit-Ethernet system is proposed. It monitors optical signal quality by comparing each input bit with a calibrated window, and switches to a stand-by fibre when a working fibre faces a quality degradation.
