White Paper: Deploying CPRI Fronthaul with CWDM

Deploying CPRI Fronthaul with CWDM

Migrating to a Centralized RAN architecture enables operational efficiencies and reduces costs. The challenge for Mobile Network Operators is transporting multiple CPRI channels for different wireless carriers and services (3G and 4G/LTE) to multiple cell towers over the fronthaul fiber links.

This white paper provides examples of how to transport multiple services over CPRI channels to different cell towers with Coarse Wavelength Division Multiplexing (CWDM) using iConverter CWDM Multiplexers, Add+Drop Multiplexers, and Transponders.
