Telecom Lead Europe: ZTE Corporation, China’s
second largest telecom equipment maker in association with the operator of the
largest optical transport infrastructure in Europe has completed the
field test of optical transmission with data rates of 100Gb/s, 400Gb/s and
1Tb/s.
The trail test was conducted on a trial network
comprising eight cities in Germany, including Darmstadt, Stuttgart and
Nurnberg.
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. The new technology can increase network
capacity with backwards compatibility and prospects for scalable extension,
while reducing the complexity and cost per bit,” said Chen Yufei, Bearer
Network general manager at ZTE.
The experiment was done to address important issues that
concern operators and vendors around network evolution towards and beyond 100Gb.
The equipment used during the trial was based on technologies such as coherent
detection, QPSK/16QAM modulation and innovative digital signal processing.
ZTE used its 100Gb OTN products (ZXONE 8000 series),
400Gb prototype and 1Tb prototype for the trial transmission.
The company said that teams from ZTE and the network
operators 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 100Gb/s channels with a large performance
margin.
ZTE introduces multi-application 400G and 1T DWDM prototype
Recently, ZTE unveiled the world’s first 400G/1T dense
wavelength division multiplexing (DWDM) multi-application network device
prototype.
The company claims that the new device prototype can
carry out seven different network applications depending on a carrier’s
requirements.
