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.
