Key Technologies For Seamless Full Duplex Integration Of Hybrid Passive Optical Networks(PON) With Radio Over Fiber (RoF)

The mounting customer demands for bandwidth-desirous services are deriving for a cost effective, robust, and high capacity access network. Even now, the end users expect a satisfactory and economical delivery of "Quad-play" applications (voice, video, data, and mobility) and rich-media applications (multimedia, interactive gaming, and meta-verse) over the access network. In last two decades, a remarkable evolution of access networks is observed both in wired and wireless, predominantly driven by ever-changing bandwidth requirements.The integration of wired and wireless domains in the access landscape that presents a technical analysis of optical architectures suitable to support radio over fiber (RoF) is the focus of this thesis. RoF is a perfect technology for the integration of wireless and wired networks that it aggregates the best features of both communication technologies. A wireless connection releases the end-user from the restrictions of a physical link to a network that results in mobility, flexibleness, and ease of use. Whereas, optical networks offers immense amount of bandwidth that appease the most bandwidth voracious customers compared to bandwidth limited wireless networks. Hence, RoF provides the best optimum solution to end-users by allowing them to maintain their mobility along with the needed bandwidth for both current and future communication/entertainment applications. Moreover, RoF networks also deliver greater geographical coverage and tractability as compared to using either wired or wireless technology. Thus, the integration of millimeter radio wave and passive optical network has the ultimate potential to make the networks more ubiquitous, dynamic and robust.However, mm-wave frequencies suffer many propagation impairments through the air that limit to a very short-range free space distance and ensue microcell and pico-cell coverage. So, to implement mm-wave fiber-radio network, the cost of the base station (BS) needs to reduce and to shift the system complexity and expensive devices to the central office (CO). The capability of the feeder fiber optic networks for integrated mm-wave RoF systems can be improved by employing hybrid PON (TDM-WDM) that is an efficient, simple and economical way to utilize the available vast bandwidth of the fiber. This research work carries on studying the adoptable, simple and cost effective model for identification and delineation of integrated multi-Gbit/s mm-wave RoF systems with PON. Another hybrid system in the frame of this work aimed for an uncompressed ultra-high definition television (UHDTV) with a resolution16times more from current high definition TV transmission over a passive optical network for video conferencing with high resolution and extremely low latency.
