Numerical Implementation of a Wideband Chaotic Light Based Ring-and-Spur Long-Reach Passive Optical Network: Architectures and Real-Time Secure Communications
In this paper, a wideband chaotic light based ring-and-spur long-reach passive optical network (ring-and-spur LR-PON) is proposed and numerically demonstrated. The bidirectional long-haul secure communication between the optical line terminal (OLT) and the optical network unit (ONU) is realized, in which the bandwidth of the chaos carrier is more than 20 GHz. As a result, the data rate can reach up to 10 Gb/s for each wavelength channel. The proposed network has potential practical values, owing to its advantages such as providing a higher bit rate, achieving a higher level of real-time security, survivability, etc.
