Traditional CATV networks are facing critical pain points: insufficient bandwidth ceiling, high O&M costs caused by massive active nodes, limited room for value-added service expansion, and low asset utilization due to redundant construction. This solution adopts an all-optical upgrade framework that replaces the traditional coaxial cable architecture with fiber-optic transmission. Through full-process design covering headend optimization, trunk transmission upgrade, and passive retrofitting of the distribution network, it improves network bearing capacity, optimizes operating efficiency, expands the space for value-added services, and helps operators achieve smooth network evolution.
