A team at the Optical Networks Group at University College London (UCL) has sent 178 terabits per second through a commercial single-mode optical fiber that has been on the market since 2007. It's a record for the standard single-mode fiber widely used in today's networks, and twice the data rate of any system now in use. The key to their success was transmitting it across a spectral range of 16.8 terahertz, more than double the broadest range now in commercial use.

伦敦大学学院 (UCL) 光网络组的一个团队通过自 2007 年上市的商用单模光纤每秒发送 178 TB 的数据。这是广泛使用的标准单模光纤的记录当今的网络，以及目前使用的任何系统的两倍数据速率。他们成功的关键是在 16.8 太赫兹的光谱范围内传输它，是目前商业使用的最宽范围的两倍多。
