ZTE achieves 1 Tb breakthrough in Western Europe

ZTE partnered with western European operator and completed data rates of 100Gbps, 400Gbps and 1Tbps during field trial in western Europe.

A joint team of engineers from both sides completed the field test on a trial network comprising eight cities in Germany, including Darmstadt, Stuttgart and Nurnberg. The equipment used during the trial was based on advanced technologies such as coherent detection, QPSK/16QAM modulation and innovative digital signal processing.

Using ZTE’s 100Gb OTN products (ZXONE 8000 series), 400Gb prototype and 1Tb prototype, the team succeeded in simultaneous transmission on 100Gbps, 400Gbps and 1Tbps WDM channels over 2,150 km, passing 26 spans with gain flattening EDFAs (Erbium Doped Fiber Amplifier).

The team also achieved 2,450 km of successful transmission on two simultaneous 100Gbps channels with a large performance margin. The transmission distances for the respective configuration in both experiments set a significant milestone in the industry.

"In terms of scale and novelty, this field trial is world leading, and it showcased the design capability of ZTE’s 100Gb / 400Gb /1Tb optical transmission systems,” said ZTE Bearer Network general manager Chen Yufei.

The new technology can increase network capacity with backwards compatibility and prospects for scalable extension, while reducing the complexity and cost per bit. Being on the cutting edge of research and development, ZTE’s optical network solution will enable network operators to meet tomorrow’s challenges of soaring traffic growth in the backbone transport network, as demonstrated by the successful trials he added.

ZTE's 400Gbps and 1Tbps DWDM prototypes are capable of providing seven different solutions for a range of network applications in a single device.
