  • NTT 使用多芯光纤电缆和大规模 MIMO 信号处理,在实地测试中实现了 455 Tbps 的传输速度,即使在风雨等环境条件下也能保持稳定传输。
  • 这一突破使 NTT 能够使用 12 个光纤芯进行并行传输,与传统系统相比,容量增加了 50 多倍,为未来高容量光网络提供了可能。

发生了什么:NTT 的多芯光纤突破

日本的 NTT 宣布在高容量骨干网络方面取得突破,利用多芯光纤电缆和大规模 MIMO 信号处理实现了 455 Tbps 的稳定信号传输。这一成功在模拟风雨和土木工程等环境因素的实地测试中得到了验证,这些因素通常会干扰信号传播。

NTT 解释说,与数据通过单芯传输的传统光网络不同,它成功使用了多芯进行并行信号传输。这增加了通道数量和容量,同时保持了与当前光纤相同的 0.125 毫米直径。该公司耦合了 12 个光纤芯,并在接收端使用数字信号处理来减少相邻芯之间的干扰。 另见: FCC 以许可限制支持光纤建设者.

该测试中,NTT 在 53.5 公里的距离上实现了 455 Tbps,在 1,017 公里的距离上实现了 389 Tbps,这一距离相当于连接东京、名古屋和大阪的日本主要光纤骨干网。这一突破可能对未来的光纤网络能力产生重大影响。NTT 认为,多芯光纤可能成为未来光传输系统的关键技术,提供超过传统系统 50 倍的容量。随着人工智能和高容量移动网络推动全球数据流量的增长,NTT 强调需要更强大的地面光网络。 另见: Ofcom 揭露英国铁路移动覆盖差距.

此进展是在其他公司取得类似里程碑之后取得的,包括诺基亚、澳洲电信Verizon,尽管 NTT 的结果通过多芯协同工作超越了这些速度。虽然 NTT 尚未明确该技术何时商业化,但它正与富士通合作,为 2030 年代的 IOWN 概念和 Beyond 5G/6G 时代开发高容量网络。

为何重要

NTT 使用多芯光纤实现 455 Tbps 的突破对未来全球通信至关重要。随着人工智能和移动网络推动数据流量的增长,现有系统难以跟上。这项创新通过使用 12 个光纤芯代替单芯来提高网络容量,在保持相同光纤尺寸的同时实现更快的数据传输。它可以提供超过现有系统 50 倍的容量,满足对更快、更可靠网络日益增长的需求。测试表明,该技术可以在风雨等恶劣条件下工作,使其更具弹性。这一突破有可能改变光传输系统,实现更快、更稳定的互联网连接。虽然仍在开发中,但 NTT 与富士通的合作旨在于 2030 年代将该技术商业化,为 5G/6G 网络的演进做出贡献。 另见: 欧盟重写人工智能基础设施主权规则.
