5G Fronthaul Transmission

The semi-active CWDM system adopts asymmetric equipment form, which is composed of AU active CWDM equipment, AAU passive CWDM equipment, color optical module at DU side, color optical module at AAU side and network management system. The semi-active CWDM can provide protection and automatic switching mechanism, and support management, operation and maintenance of front-haul network. DU Active CWDM equipment and AAU passive CWDM equipment multiplex several wavelengths for transmission to save fiber resources. The system can support the mixed transmission of 4G / 5G services at the same time to realize the unified front-haul transmission of 4G / 5G.
