This is the most advanced experiment to date in electrical division multiplexing (ETDM) based on 16QAM signals. The result sets a benchmark for the global optical networking industry, further boosting the development of new technologies and supporting the new generation of transport standard to address the exponential growth of IP traffic.
ZTE has successfully achieved high-speed single-carrier WDM transmission of 120 Gbaud ETDM and PDM-16QAM optical signals. This was accomplished by utilizing optical pre-emphasis and receiver-side MLSE to mitigate the filtering reduction effect caused by the bandwidth limitations of the optoelectronic components. Twelve 150 GHz WDM channels, each loaded with 960 Gb/sa over 1,200 kilometers, based on 100 km spans of TeraWave™ optical fiber, have been verified.
Dr. Jianjun Yu, Chief Scientist at ZTE Optical Lab USA: "Thanks to the generation of high-speed transmission signals, transport interfaces with bit rates of up to 1 TB/s will be achievable in the near future. We can expect that bit rates greater than 1 TB/s will be introduced as standard rates for Ethernet as a logical evolution for the 400Gb interface, which is based on high-speed transmission signals and high-order modulation formats. ZTE has been relentless in driving research and development of 400G single-carrier transmissions, and also possesses key technologies for future Tb/s solutions.".
ZTE has been committed to the development of 400G/1T technology and applications, delivering several key innovations in this field. In 2013, ZTE completed 400Gb/s data signaling over a distance of 5,000 kilometers, using 25 reconfigurable add-drop multiplexer (ROADM) nodes without electrical repeaters. In 2015, ZTE's US Optical Laboratory collaborated with OFS America to achieve a 10,000-kilometer single-carrier PDM-QPSK transmission, setting a world record for 400Gb/s transmission. In January 2016, together with T-Mobile Austria, ZTE successfully completed a 10G/100G/400G hybrid transmission trial on existing networks, demonstrating that 400G Optical Transport Networks (OTNs) are suitable for complex, long-distance applications.
