On the one hand

with the rapid development of China Mobile cable broadband users

the occupancy rate of wired broadband ports is getting higher and higher

single PON mouth with more and more users

it is difficult to meet the multi-user high-bandwidth concurrent demand. On the other hand

with the Internet TV

4 K

3 D and video games and other emerging business development

fast or even Gigabit users increasingly strong demand

and the existing network can not fully support the high-bandwidth business development needs

bandwidth upgrade speed is imminent. In this paper

we focus on the FTTH access scenarios of China Mobile’s strong and high-value sites

analyze the requirements of speed expansion

propose to reduce the splitting ratio scheme and upgrade the 10 GPON scheme. The project should adopt the suitable speed improvement scheme according to the actual situation.
