The light is a form of carrier wave that is modulated to carry information. E/O converters use light-emitting elements such as semiconductor lasers, O/E converters use light-receiving elements such as photodiodes, and optical elements such as lenses are used at the input and output of optical fiber. It takes electrical signals, which carry the information to be transmitted (like a digital file or voice call), and transforms them into light pulses suitable for. Canada produces 40% of the worlds optoelectronic products (Nortel, JDS Uniphase, Quebec Photonic Cluster.
