PPT-Single wavelength / channel optical communication

The simplest optical communication scheme is single wavelength channel communication The light from a single laser VCSEL DFB laser etc is electricallymodulated and sent through a single or multimode fiber. Division Multiplexing CO-OFDM. 1. Principle of orthogonal frequency-division multiplexing (OFDM). The principles of orthogonal frequency division multiplexing (OFDM) modulation have been in existence for several decades. However, in recent years these techniques have quickly moved out of textbooks and research laboratories and into practice in modern communications systems. The techniques are employed in data delivery systems over the phone line, digital radio and television, and wireless networking systems. Communication Infrastructure for Next-Generation .
