Fujian Radio & Television MAN Wavelength Division Project

Background: Fujian Cable Radio and Television Network Co., Ltd. is one of the largest local radio and television network operators in China. Focusing on the strategy of "High Definition Fujian, Smart Radio and Television", the company aims to build a comprehensive service operator.

Technical Task: Connect two sites located ~30 km apart with fiber redundancy to ensure uninterrupted communication even in the event of a fiber break. Total inter-site capacity exceeds 100Gbps using DWDM technology.

DWDM Redundancy 30km Span

Three-Data-Center Ring with Channel Redundancy

Technical Task: Develop a switching scheme between three data centers connected via single optical fiber. Each node must have links on two independent routes for full redundancy.

Initial Data: The customer requires 20 Gbps capacity between each node. The solution implements a ring topology with automatic protection switching (APS) and OTN layer monitoring.

Ring Topology 20Gbps per Link APS Protection

Data Center
