We present results from the first gridless networking field trial with flexible spectrum switching nodes and 620 km of installed fibre links. Signals at 10G, 12.25G, 42.7G, DP-QPSK 40G, DP-QPSK 100G and 555G are generated, successfully transported and switched using flexible, custom spectrum allocation per channel. Spectrum defragmentation is demonstrated using integrated SOA-MZI wavelength converters. Results show error-free end-to-end performance (BER<1e-9) for the OOK channels and good pre-FEC BER performance with sufficient margin to FEC limit for the 40G and 100G coherent channels as well as for the 555G super-channel.
我们展示了首个采用灵活频谱切换节点和620公里已安装光纤链路的无网格网络现场试验结果。通过为每个通道灵活分配定制频谱，成功生成、传输并切换了10G、12.25G、42.7G、DP-QPSK 40G、DP-QPSK 100G和555G的信号。使用集成的SOA-MZI波长转换器展示了频谱碎片整理。结果表明，OOK通道实现了无差错的端到端性能（误码率<1e-9），40G和100G相干通道以及555G超通道的前向纠错误码率性能良好，与前向纠错限制相比有足够余量。
