|

<h4>技术物理极限的突破：为何是革命？</h4>
|
||
<p>传统实芯光纤受限于石英玻璃介质，存在时延、色散和非线性效应三大物理瓶颈。空芯光纤通过“空气”传输光信号，从根本上解决了这些问题：</p>
|
||
<ul>
|
||
<li><strong>超低时延:</strong> 光速提升近50%，时延降低约30%-33%（从5μs/km降至3.4μs/km）。这是AI时代，特别是跨数据中心的大规模分布式计算和高频交易等场景的“刚需”。</li>
|
||
<li><strong>大容量与低损耗:</strong> 非线性效应降低1000倍，允许更高的光功率传输，理论上可提升5倍传输能力。同时，理论损耗极限低于传统光纤（0.1dB/km vs 0.14dB/km），可减少昂贵的中继器部署。</li>
|
||
</ul>
|
||
|
||
<h4>长期发展路径</h4>
|
||
<ol>
|
||
<li><strong>第一阶段 (当前-2026年): 高端DCI场景渗透。</strong>由北美云巨头和国内运营商引领，应用于对时延最敏感的场景。此阶段特征是“以产定销”，价格高昂。</li>
|
||
<li><strong>第二阶段 (2026-2028年): 成本下降与应用拓展。</strong>随着规模效应和工艺成熟，成本显著下降。应用场景从DCI向骨干网、城域网等延伸。</li>
|
||
<li><strong>第三阶段 (2028年以后): 全面渗透与生态成熟。</strong>成本进一步降低，有望成为下一代光网络的标准配置。微软预测的2030年100万公里产能是对这一阶段的远景展望。</li>
