Currently, China Unicom has achieved great success in global first carrier-class land optical fiber application project. ZTT independently new developing G.654 low-loss optical fiber has successfully applied to this project.
Most worthy of mention is ZTT G654 has solved problems like spectral efficiency, transmission distance, system capacity of this global first project and achieved good equipment matching with China Unicom. Besides, China Unicom has also highly praised ZTT for its research and production capacity. ZTT would prepare to make greater contributions for promoting the coming early of 400G optical communication times.
