5G commercial, bearer first. With the accelerated deployment of 5G networks, as one of the basi c carriers of the entire 5G industry, the demand for 5G fronthaul networks is becoming stronge r. In the 5G era, the radio access network is mainly based on the C-RAN architecture, DU is de ployed in a centralized manner, and multiple AAUs are connected through the fronthaul network. T he fronthaul 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; Xintai Communication is committed to building a high-quality 5G fronthaul netwo k, It is the first to launch a 5G fronthaul semi-active solution, which improves the reliabili ty of the network and also improves the manageability and operation and maintenance of the fronthaul network.

Program features

  • Support CPRI 1~10 and eCPRI (10G/25G), compatible with STM-1/4/16/64, GE/10GE/25GE and othe r multi-service unified bearer, transparent transmission, maximize the value of fronthaul network

  • Modular configuration, 1:6/12/18 optional, can achieve multi-directional multi-level convergence, large-scale fiber saving

  • A variety of color light modules can be provided, supporting CWDM 18 waves, MWDM 12 waves, and meeting various line power budget index requirements

  • Support optical layer 1:1 protection, protection switching time is less than 50ms, improving network reliability

  • Supports graphical interface network management, reconstructs wireless and transmission management domains, and realizes full monitoring of optical module and line status
  • The active WDM equipment at the central office supports AC 220V and DC -48V power supply options, 1+1 power input protection, and the equipment power failure does not affect business transmission
  • Remote passive WDM has outdoor deployment capabilities and flexible deployment locations

Application scenario

  • Mainly meet the needs of end point-to-point CRAN networking scenarios, the distance between DU and AAU sites is within 10km

  • In areas where optical fiber resources are scarce, there is no pipeline resources, and new optical fibers are laid unconditionally

  • Build a high-quality fronthaul network to support 5G high-reliability business needs
