mm-wave and Wi-Fi transmission over single and multi-mode optical fibers

This paper explores the simulation design and transmission of a 60GHz mm-wave and Wi-Fi (IEEE 802.11n) transmission over a coupled long-haul Single Mode Fiber (SMF) and Multi-mode Fiber (MMF) to a residential station by utilizing optical carrier suppression (OCS) modulation at the central office. This topology includes the use of a dual drive Mach-Zehnder modulator (DD-MZM) to realize Remote Heterodyne Detection (RHD) and Wavelength-Division Multiplexing (WDM) to separate both modulated optical signals. At the receiver station, an offset launch is applied at the junction where SMF is coupled with MMF to improve the signal bandwidth by applying Offset Launch theory. The transportation of mm-wave wireless signals within radio-over-fiber network causes impairments on the signals, some of which are fiber modal and chromatic dispersion. In this paper, we apply such a unique theory that increases signal bandwidth by mitigate the pulse broadening witnessed on a signal as a result of modal dispersion in the Multimode fiber.
