C114讯 北京时间3月16日下午消息（张月红）据海外媒体报道，中兴通讯完成了数据传
输率高达1.7Tbps的光纤网络设备的现场演示。基于WDM的光纤系统可使用8个信道传输
数据，每个信道的容量为216.4Gbps，采用多路复用QPSK调制方式，演示中的传输距离
为1750千米，所使用的是标准的单模光纤。
这项技术的成功演示对运营商来说，从100Gbps传输系统向200Gbps系统升级是可能的，
200Gbps在每比特的成本更低，对频谱的利用率的有25%的提升，可以更长远地应对消费
者对数据传输的需求。
中兴正在致力于100G和超100G的研究，除上述演示外，中兴还完成了单通道11.2Tbps的
光纤信号传输试验。
当前，电信运营商正处于从40Gbps向100Gbps升级的进程中，市场研究公司Infonetics
称，运营商们计划在现有网络中同规模使用40G和100G系统，但很明显地倾向于100G。
Experiment proves seamless upgrade to 200G possible
15 March 2012, Shenzhen, China – ZTE Corporation ("ZTE") (H share stock
code: 0763.HK / A share stock code: 000063.SZ), a publicly-listed global
provider of telecommunications equipment and network solutions, announced it
has conducted an industry first field demonstration of a 8x216.4Gb/s WDM
transmission through a 50GHz optical spectrum grid.
The demonstration utilized patented ZTE high-frequency technology to
accomplish a 200Gb/s polarization multiplexing QPSK signal transmission at
50GHz through 1,750km of standard single model fiber optic cable. This
resulted in a 25 per cent increase in spectrum efficiency and an increase in
transmission efficiency. The experiment proves a seamless upgrade from a
100G transmission system to a 200G system is possible. A record of the
demonstration was presented at the OFC/NFOEC 2012 conference.
ZTE is committed to 100G and beyond-100G research. The company was the first
in the world to successfully complete a single-channel 11.2Tbit/s optical
signal transmission experiment.
ZTE is also an industry leader in next-generation bearer network solutions
and high-speed optical communications transmission technology. As such, it
was the first company to release whole-course 100G solutions in 2010. The
company has completed several trial network projects in the 100G and beyond-
100G fields with the mainstream operators from China, Germany, Russia and
the United States. | s*****t
