5G Fronthaul Semi-Active WDM Solution

5G commercial, bearer first. With the accelerated deployment of 5G networks, as one of the basic carriers of the entire 5G industry, the demand for 5G fronthaul networks is becoming stronger. In the 5G era, the radio access network is mainly based on the C-RAN architecture, DU is deployed in a centralized manner, and multiple AAUs are connected through the fronthaul network. The frontal solutions considered by C-RAN are mainly optical fiber direct drive, passive WDM, and active OTN solutions, which have problems such as high fiber resource consumption, no control, and high cost; Sintai Communication is committed to building a high-quality 5G fronthaul network, It is the first to launch a 5G fronthaul semi-active solution, which improves the reliability of the network and also improves the manageability and operation and maintenance of the fronthaul network.
