数据中心 Scale-across(FST全谱转发器、多rail、ZR/ZR+/CL、跨楼/园区/区域DC网络需求与架构)
ECOC 2026 洞察
一句话结论: Scale-across 的部署单位正从”波长”转为”光纤对”,相干可插拔(800ZR+ 量产、1.6T ZR/ZR+ 与 Coherent-Lite 跟进)负责单波长成本与功耗,全谱转发器(FST)+ 多rail线路系统负责光纤对/机房/功耗的规模化,空芯光纤(HCF)与 OCS/OTN 协议层则从时延与利用率两端争取跨楼到区域尺度的训练效率;瓶颈已从模块转移到线路系统、光纤数量与热设计。
核心判断
- 需求已从”DCI 的一个增量”变成”云可插拔带宽的主体”,且由线路系统而非模块决定成本结构。
- FST + 多rail 是”光纤对”时代的架构答案,收益以设备数、机房数、功耗三个量级表达(均为厂商自报)。
- 相干向短距渗透的分界由色散与延迟预算决定:>10 km 用 C 波段 ZR/ZR+,2–10 km(至 20–40 km 园区)用 O 波段 Coherent-Lite;分界线之争的核心是 O 波段 IM/DD 能否用光域均衡突破色散壁垒。
- 功耗与热是相干可插拔在 1.6T 的硬约束,形态将分叉为风冷 QSFP-DD/OSFP(<45 W 天花板)与液冷 XPO。
- HCF 在 DCI 的价值已由”低损耗”转为”时延 + 无非线性 + 可用 ZR”,但量产、成本、熔接与 OTDR 生态仍是硬缺口,至少 12–24 个月内是选择性部署而非默认。
