A Proposal for Bandwidth Consumption in FTTH Networks in China

FTTH development is slow but steady in China. The phenomenon is rooted from some major challenges, such as cost, limited bandwidth in metro networks, bandwidth consumption behaviours. To address above challenges, FTTH architectures and bandwidth consumption behaviours are studied in the paper. To remove the bandwidth bottleneck between access and Metro networks and reduce cost, LR-PON (Long-Reach Passive Optical Network) is suggested to be applied in two ways in China. For resolving the challenge of bandwidth exhaustion in Metro networks caused by high-capacity consumption in access networks, a new bandwidth scheduling, Bandwidth on Schedule (BoS) is proposed to improve efficiency of bandwidth utilization. In the paper, the proposed solutions to challenges will be helpful to increase the penetration rate of FTTH deployment in China.
