我们以数值方式研究了光纤接头和光纤连接器对模式复用多模光纤链路中模式相关损耗 (MDL) 和多输入多输出 (MIMO) 中断容量统计的影响。我们的结果表明，在长途传输系统中实现合理的停电容量所需的熔接损耗比目前可行的要低得多。低至 0.03 dB 的熔接损耗可能会在仅几百公里的传输长度后有效地导致 MIMO 通道中断。在第一个近似值中，相对容量仅取决于累积的熔接损耗，并且应小于大约 2dB 以确保 90% 的相对容量。我们还表明，传输线内的离散模式排列（混合）可以有效地将传统熔接损耗的最大传输距离增加 5 倍。 (C) 2013 美国光学学会
We investigate numerically the influence of fiber splices and fiber connectors to the statistics of mode dependent loss (MDL) and multiple-input multiple-output (MIMO) outage capacity in mode multiplexed multi-mode fiber links. Our results indicate required splice losses much lower than currently feasible to achieve a reasonable outage capacity in long-haul transmission systems. Splice losses as low as 0.03 dB may effectively lead to an outage of MIMO channels after only a few hundred kilometers transmission length. In a first approximation, the relative capacity solely depends on the accumulated splice loss and should be less than approximate to 2dB to ensure a relative capacity of 90%. We also show that discrete mode permutation (mixing) within the transmission line may effectively increase the maximum transmission distance by a factor of 5 for conventional splice losses.
