ZTE Corporation (0763.HK / 000063.SZ), a major international provider of telecommunications, enterprise and consumer technology solutions for the Mobile Internet, completes an ultra-high-speed 200Gbps optical communication coding investigation and verification system, demonstrating the record-setting throughput among the same type systems.
Based on the system, ZTE completed the research test on the latest 400ZR-FEC solution drafted by the Optical Internetworking Forum (OIF). ZTE’s research work revealed a performance degradation of the 400ZR-FEC at ultra-low bit error rate (BER) as well as its root cause that is invisible to existing soft-ware based simulation and verification means, ZTE’s further investigations indicated directions for resolving the problem.
This work demonstrated at 200Gbps for the first time a practical, effective, and efficient thorough investigation on coding performance at ultra-low BERs down to 10-15 , exerting a critical influence on the OIF 400ZR-FEC standards to be determined in April 2018. The report of the research has been accepted as a post-deadline paper at this year’s Optical Fiber Communication Conference and Exhibition (OFC).
Post-deadline papers at OFC represent the industry’s most influential research results selected globally by the Technical Program Committee of the conference, which is composed of the top experts in the industry and academia. These papers are presented in the closing day of the conference.
ZTE’s recent verification results on the OIF 400ZR-FEC solution are timely, cutting-edge and rigorous in argumentation, and will have a direct influence on the completion of the next-generation 400G optical communication standards. It is also the first time that a research achievement led and completed by a Chinese enterprise in the optical communication algorithm category was accepted as a post-deadline paper at OFC, which demonstrates ZTE’s leading position in technological innovation and product development in the optical communication field.
“ZTE’s ultra-high-speed 200Gbps optical communication coding investigation and verification system resolves the problem of coding performance investigation in the optical communication systems at ultra-low post-decoding BERs, which has been a challenge facing the academia and the industry for more than 20 years. Employing this system, ZTE completed the investigation and verification of the OIF 400ZR standards proposal within two weeks. The demonstrations would have a long-trem and profound influence on the error-correction coding research in optical communications,” said Dr. Yi Cai from ZTE in the post-deadline paper presentation.
ZTE has long been committed to providing 400G/1T technology with important R&D resources. So far, ZTE has submitted dozens of patent proposals involving optical modulators, framers, chips and algorithms, and has accomplished a number of key innovations in the high-speed optical communication field. So far, ZTE has deployed more than 400 100G and beyond commercial networks and trial networks for high-end operators in Asia-Pacific, Europe, America and Africa, with the total fiber length exceeding 400,000 km.
