ZTE Corporation has partnered with the operator of the largest optical transport infrastructure in Europe on a field trial for optical transmission with data rates of 100 Gb/s, 400 Gb/s and 1 Tb/s.
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 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 100Gb/s, 400Gb/s and 1Tb/s WDM channels over 2150 km, passing 26 spans with gain flattening EDFAs (Erbium Doped Fiber Amplifier). The team also achieved 2450 km of successful transmission on two simultaneous 100 Gb/s channels with a large performance margin.
Commenting on the trials, Chen Yufei, general manager, bearer network, ZTE said, ?In terms of scale and novelty, this field trial is world leading, and it showcased the design capability of ZTE?s 100 Gb and 400 Gb /1Tb optical transmission systems. The new technology can increase network capacity with backwards compatibility and prospects for scalable extension, while reducing the complexity and cost per bit. 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.?
