4G / 5G transmission :
In the 5G fronthaul, if the optical fiber is used to directly connect RRU and DDU, it will consume a lot of optical fiber resources. If the wave division multiplexing system is used, the optical fiber resources can be saved.
D-NET mainly produces WDM products,5G fronthaul can use wave division multiplexing (WDM) technology to provide 1:6 and 1:12 multiplratios on 1-core optical fiber to carry 3/6 services, and realize service transmission at different rates by config color modules of different rates (10Gbps and 25Gbps).
