These technologies are optical channel multiplexing, information modulation using advanced techniques, and signal detection. Currently, the first step for the implementation of 5G mobile networks, after economic and coverage considerations, in other words, strategic positioning of antennas based on studies, is the design of the optic fiber transport network architecture to support the massive data flow coming from the antennas that communicate with the users of 5G networks. In this research, we study the optical interface technologies of 5G networks, emphasizing those used for the development of the simulations presented in section seven, called Results Obtained; we chose these technologies based on the ITU recommendations that separate the architecture of the transport network for 5G mobile communications and establish the supported and future data rate for the links, as well as its recommendations for NGN or next-generation networks by standardizing the operation of transport networks and wavelength distribution networks that are convergent. In the same way, the physical and technical characteristics of the optical interface of this type of network must have been shown, depending on which part of the transport network architecture is studied: front-haul, mid-haul, or backhaul. Simulations of modulation and multiplexing techniques are performed in a 5G optical front-haul using PAM4 high-level modulation and SWDM and M-WDM optical channel multiplexing typical of 5G mobile networks for bidirectional communications from the RRHs or remote radio heads to a DU to verify the eye diagrams generated over 400 meters and 10 km for the simulations presented. Within the optical front-haul simulations, we showed how SWDM optical multiplexing presents better characteristics than M-WDM using two-core fiber and shorter distances. In the same way, the development of a PAM4 modulator in the Optisystem 19 optical network simulation environment we showed, which triples the Q factor within the eye diagram analysis of the signals in reception in a 5G optical front-haul compared to one elaborated with native blocks within the program.
