LAN emulation on passive optical networks using RF subcarrier multiplexing

Abstract

An emulation technique of local area networks (LAN) on passive optical networks (PON) using RF subcarrier multiplexing was presented. The technique requires a single wavelength source at each optical network units for transmission of upstream baseband. The carrier sense multiple access with collision detection (CSMA/CD) protocol can also be adopted by reusing the redirected signals for carrier-sensing and collision detection. It was observed that the power margin decreases with the increase in the number of ONUs.
