| Abstract: | The large-scale construction of 5G base station consumes a lot of basic resources of fronthaul fiber,which brings the pressure of network construction cost and energy consumption to operators.By comparing various fronthaul schemes and analyzing from the aspects of technology,construction period and cost-effectiveness,it is proposed that passive WDM scheme should be adopted in the area with insufficient fiber core,which can greatly save construction cost,shorten construction period,reduce the investment in power transformation of equipment rooms and reduce operation cost.The scheme can optimize the integrated TCO,efficiently solve the 5G fronthaul problems and improve the network competitiveness. |
