论文摘要
地中海底部的KM3NET中微子望远镜的光学数据传输系统将在检测器阵列中提供6000多个光学模块中的每个模块中的每个模块，并在岸上与控制站有点对点的光学连接。 KM3NET的ARCA和ORCA检测器分别以约3500 m和2500 m的深度安装；他们到控制站的距离约为100公里和40公里。每个光学模块的预期最大数据速率为200 Mbps。实施的光学数据传输系统与深海电源电缆和接线盒网络的布局相匹配。为了有效使用系统中的纤维，应用密集波长乘积的技术。出现了光学系统的性能，以测量的位错误率，光学预算和系统实现的下一步。
The optical data transport system of the KM3NeT neutrino telescope at the bottom of the Mediterranean Sea will provide each of the more than 6000 optical modules in the detector arrays with a point-to-point optical connection to the control stations onshore. The ARCA and ORCA detectors of KM3NeT are being installed at a depth of about 3500 m and 2500 m, respectively; their distance to the control stations is about 100 kilometers and 40 kilometers. The expected maximum data rate is 200 Mbps per optical module. The implemented optical data transport system matches the layouts of the networks of electro-optical cables and junction boxes in the deep sea. For efficient use of the fibres in the system the technology of Dense Wavelength Division Multiplexing is applied. The performance of the optical system in terms of measured bit error rates, optical budget and the next steps in the implementation of the system are presented.
