年俄罗斯入侵乌克兰以来，针对海底电缆的可疑袭击事件有所增加，其中包括在波罗的海发生的几起事件。 联合国非常重视这些破坏行为， 并在 12 月成立了一个保护海底电缆的国际组织。</p><p id="3FV0Q2SL" style="box-sizing: inherit; margin: 34px 0px; padding: 0px; text-align: justify; color: rgb(64, 64, 64); font-family: Arial, "Hiragino Sans GB", STHeiti, "Helvetica Neue", Helvetica, "Microsoft Yahei", "WenQuanYi Micro Hei", sans-serif; font-size: 18px;"> 德国开发商和制造商 AP Sensing 创造了分布式光纤传感 (DFOS) 技术，该技术可以在海底电缆即将受到攻击时向官员发出警报。</p><p id="3FV0Q2SM" style="box-sizing: inherit; margin: 34px 0px; padding: 0px; text-align: justify; color: rgb(64, 64, 64); font-family: Arial, "Hiragino Sans GB", STHeiti, "Helvetica Neue", Helvetica, "Microsoft Yahei", "WenQuanYi Micro Hei", sans-serif; font-size: 18px;"> 据英国广播公司报道，当光脉冲沿着光纤股传播时，有时会沿着该线路反弹回来微小的反射。 这些反射受到声波振动以及温度和光缆本身<a href="http://theory.oecr.com" target="_blank" class="relatedlink">物理</a>干扰等因素的影响。 例如，埋在地下的部分电缆的温度变化可能会<a href="http://display.oecr.com" target="_blank" class="relatedlink">显示</a>出电缆已被拆除。</p><p id="3FV0Q2SN" style="box-sizing: inherit; margin: 34px 0px; padding: 0px; text-align: justify; color: rgb(64, 64, 64); font-family: Arial, "Hiragino Sans GB", STHeiti, "Helvetica Neue", Helvetica, "Microsoft Yahei", "WenQuanYi Micro Hei", sans-serif; font-size: 18px;"> "穿过光纤的声波能量基本上会干扰我们的信号。 我们可以<a href="http://opticaltest.oecr.com" target="_blank" class="relatedlink">测量</a>这种干扰，"AP Sensing 全球销售经理 Daniel Gerwig 说。</p><p id="3FV0Q2SO" style="box-sizing: inherit; margin: 34px 0px; padding: 0px; text-align: justify; color: rgb(64, 64, 64); font-family: Arial, "Hiragino Sans GB", STHeiti, "Helvetica Neue", Helvetica, "Microsoft Yahei", "WenQuanYi Micro Hei", sans-serif; font-size: 18px;"> 利用这项技术，可以确定经过海底电缆上方的船只的大致尺寸、位置，有时还能确定其行驶方向。 它还能探测到潜水员是否触及电缆、附近是否有锚掉落以及发生损坏时的位置。</p><p id="3FV0Q2SP" style="box-sizing: inherit; margin: 34px 0px; padding: 0px; text-align: justify; color: rgb(64, 64, 64); font-family: Arial, "Hiragino Sans GB", STHeiti, "Helvetica Neue", Helvetica, "Microsoft Yahei", "WenQuanYi Micro Hei", sans-serif; font-size: 18px;"> 该公司表示，如果有闲置的光纤，或者已点亮的光纤有足够的空闲通道，就可以将监控功能添加到现有的光缆中。</p><p id="3FV0Q2SQ" style="box-sizing: inherit; margin: 34px 0px; padding:

该系统有其局限性。 它只能探测到几百米范围内的振动，而不是几公里范围内的振动，而且大约每隔 100 公里（62 英里）就需要安装一个监听站（询问器）。</p><p id="3FV0Q2SR" style="box-sizing: inherit; margin: 34px 0px; padding: 0px; text-align: justify; color: rgb(64, 64, 64); font-family: Arial, "Hiragino Sans GB", STHeiti, "Helvetica Neue", Helvetica, "Microsoft Yahei", "WenQuanYi Micro Hei", sans-serif; font-size: 18px;"> AP Sensing公司表示，目前该技术已部署在北海，不久将开始<a href="http://opticaltest.oecr.com" target="_blank" class="relatedlink">测试</a>安装在波罗的海海底某处的监测电缆。</p><p id="3FV0Q2SS" style="box-sizing: inherit; margin: 34px 0px; padding: 0px; text-align: justify;

今年八月，北约警告俄罗斯可能会以海底电缆和全球定位系统为目标，破坏重要的<a href="http://ofc.oecr.com" target="_blank" class="relatedlink">通信</a>和导航系统。 该组织随后成立了HEIST（确保电信信息安全的混合空间-海底架构），旨在制定保护全球互联网流量的战略，并在全球海底电缆网络（长约 120 万公里）遭到破坏时创建替代路径。 据估计，海底光缆每天为10万亿美元的金融交易提供便利，并传输加密的国防通信。</p><p microsoft="" yahei",="" simsun;="" background-color:="" rgb(255,="" 255,="" 255);="" text-align:="" center;"="" 255);"="" center;="" style="word-wrap:
