A novel architecture for ROF-WDM PON integration using PDM and remote modulation

A novel scheme for the integration of Radio Over Fiber technique with WDM-passive optical Networks is presented. WDM Passive Optical Network (WDM-PON) is an emerging solution for the ever increasing bandwidth requirements that can support a large number of users. Wireless communication now relies on RoF technology for meeting increased demand for capacity. This work proposes a scheme to integrate Radio over Fiber with WDM-Passive Optical Networks with dual polarisation, in which a wired baseband data and a wireless radio signal are modulated onto the two polarised components of a light source. The wavelength for upstream transmission is send to the BS from the Central Station. This remote modulation achieves Base Station design simplification, which is a critical aspect in future pico cellular approach.
