According to one embodiment of the present invention, a wavelength-shifted dynamic intelligent bidirectional access optical system utilizes key optical elements such as: a quantum dot enabled semiconductor optical amplifier, a phase modulator and an intensity modulator to provide upstream optical signals. These key optical elements reduce the Rayleigh backscattering effect on the transmission of optical signals. Reduced Rayleigh backscattering effect enables a longer-reach access network topology (more than any other current access network topology) between a subscriber unit and a super node (e.g., many local nodes collapsed into one super node). Such a longer-reach access network topology eliminates operational costs and capital costs related to a vast array of middle equipment such as routers and switches, which would otherwise be needed between super nodes and many remote nodes. Furthermore, a wavelength to a subscriber unit may be protected and dynamically varied for on-Demand bandwidth, information and services and also a subscriber's unit may be configured with any array of connectivity options. Integrated micro-processors, wireless devices, wireless sensors, RFID sensors, and batteries incorporated into an intelligent device may be used to sense the environment, to process information, to initiate action and to communicate with other similar devices. Data interpretation, pattern recognition and reasoning technologies may be utilized to allow these devices to communicate with and/or without human intervention and to operate independently and intelligently. Such independent interactions with other similar devices (integrated with micro-processors, wireless devices, wireless sensors, RFID sensors and batteries) can enable the Internet of Things and/or machine-to-machine communication via an embedded algorithm/software. Such an intelligent device can also act as the remote-control for life and health. |
