This paper presents an overview of the optical transport for the 5G RAN. 2. 5G RAN disruption 3GPP has identified eight possible functional splits (FS) and associated interfaces since Release 14 for the 5G RAN architecture, also known as NG-RAN, consisting of the 5G Core Network (5GC) and 5G radio base station gNB.
In order to satisfy the need for larger transmission capacity, 5G is spreading. Large-capacity communication systems are used for the base stations where the traffic concentrates and higher-speed optical devices are applied to each layer.
Accordingly, there is demand for electro-absorption modulated lasers (EMLs) that operate with 26-Gbaud 4-level pulse amplitude modulation (PAM4) as optical devices with the transmission speed of 50 Gbps to be applied to midhaul of 5G base station networks.
Different optical layer options for 5G transport exist, from which operators will likely have to address different network scenarios and use a mix of solutions. Grey optics are the most flexible and cost-efficient solution in fiber-rich scenarios, where the RU and DU/CU are linked up by direct dark fibers per physical port.
This new computing platform relies on a sophisticated hardware/software co-design to optimize performance, power efficiency, and scalability, enabling a compact, yet adaptable and
