With the increasing volume of RAN deployments globally for macro, private 5G and CBRS deployments, there is a clear need for service providers to provide a fast and cost-effective way (given RAN costs are most of the cost for deploying mobile networks) of transporting 4G and 5G fronthaul and midhaul radio traffic based on CPRI and/or e-CPRI interfaces. This can be accomplished using DZS technology innovation via DWDM circuits in Centralized RAN (C-RAN) and Open RAN (O-RAN) networks. This innovative solution is highlighted in this new white paper from DZS.

The DZS Saber 4400 ROADM platform redefines RAN networks and expands 4G and 5G radio connectivity by providing lightning fast, cost-effective deployment scenarios for front and midhaul transport with reduced Capex and Opex. The Saber 4400 can be deployed in standard remote cabinets resulting in savings of up to $200K per site versus traditional hut solutions. The solution provides reduced latency and cost topologies critical for 5G and 4G RAN deployments using the industry’s first extended temperature and modular ROADM platform to control all aspects of radio transport. This reduces infrastructure investment, eliminating the need to deploy temperature-controlled huts and active transport equipment at cell sites. It redefines your investment approach, allowing for more investment in expandable, high-bandwidth solutions and less investment in the buildings to house them.

When multiple cell sites are connected along a single fiber for fronthaul in a linear chain topology (for example along a highway or a train track), the DWDM solution becomes more complicated. At each cell site, specific wavelengths are dropped, and others continue down the line. When an all-passive solution is used, the number of sites that can be connected in this manner is very low due to the optical losses through the chain. The DZS Saber 4400 platform-based solution can eliminate this problem. By using an active Saber 4400 ROADM system at the DU site, while retaining a passive solution at each of the cell sites, longer linear chains of cell sites can be connected, significantly reducing costs. The solution also provides an extremely low-latency, high-bandwidth solution to aggregate all the midhaul/backhaul traffic to the core network.
