Ericsson Fronthaul 6000 serve all RAN connectivity with a superior and flexible 5G optical platform. It is a flexible and cost-efficient solution for Ethernet, CPRI and eCPRI transport, separately or together. It offers market-leading fiber density, 25G capacity and negligible latency to achieve. 5G Fronthaul Connectivity Solution - As large data traffic, high speed and low latency requirements for 5G implementation, the optical fibre technology is gradually replacing traditional coaxial cable to connect Baseband Unit (BBU) and Remote Radio Unit (RRU). This new link was established to supplement to the backhaul. Abdulhalim Fayad,, Tibor Cinkler, and Jacek Rak This work was supported by CHIST-ERA Sustainable and Adaptive Ultra-High-Capacity Micro Base Stations (SAMBAS) Grant funded by Research Foundation–Flanders (FWO), Agence nationale de la Recherche (ANR), National Research, Development and Innovation. Specifically, optical technologies presented by passive optical networks (PONs) are introduced as the best suitable solution for 5G and beyond network fronthaul due to their properties of providing high capacity and low latency connections. We considered time and wavelength division multiplexed. Complete guide to selecting 25G SFP28 optical modules for 5G fronthaul networks. Compare SR, LR, ER, BiDi, and CWDM types covering transmission distance, wavelength, power consumption, and application scenarios.
