ZTE announced that it has partnered with China Telecom to complete the acceptance test of a ROADM all-optical backbone network through live streaming. ZTE reports it passed 15 mandatory test items and 14 additional ones in the test. The indexes of 100 percent recovery rate for a single fibre cut and 97 percent recovery rate for multiple fibre cuts have proven the stability and reliability of the optical network, ZTE said.
Back in 2019, ZTE won the bid for the all-optical ROADM network. The project spans 15 provinces in Northwest China. In the construction, ZTE has adopted the all-optical cross-connection technology with a 96-wavelength system. ZTE’s bandwidth adjustment has also laid the foundation for network expansion in the future.
To support transport over a long distance, ZTE's Flex Shaping algorithm has powered the network to balance bandwidth resources and transport capabilities. In addition, the visualization of resources and latency based on the management platform has provided customers with a dynamic network. ZTE has also provided "dynamic rerouting" recovery, enabling the recovery against multiple fiber cuts and increasing network stability. Therefore, ZTE says the network can address the service requirements of 5G, big videos, DC private lines and high-value financial private lines for large bandwidth.
