摘要

在短距光互连速率向200 Gbit/s/λ及以上演进的背景下，传统石英单模光纤互连系统在容量提升方面面临日益突出的物理约束。文章聚焦反谐振空芯光纤（AR-HCF）在高容量、低复杂度强度调制直接检测（IM/DD）短距光互连系统中的应用价值，按照单波高速支撑、跨波段传输验证、波分复用（WDM）容量扩展和密集WDM（DWDM）高密度容量验证的逻辑，总结了近年来基于AR-HCF的短距光互连代表性实验进展；并分析了其在信道、器件封装、调制格式和低复杂度数字信号处理方面的技术贡献。综述表明，AR-HCF通过降低色散与非线性，拓展了IM/DD系统在C+L波段实现高密度DWDM传输的物理边界，为太比特级短距光互连提供了低复杂度拓展路径。

Abstract

As short-reach optical interconnects evolve toward data rates of 200 Gbit/s/λ and beyond

the capacity scaling of conventional silica single-mode-fiber interconnect systems is facing increasingly physical constraints. This paper focuses on the application value of Anti-Resonant Hollow-Core Fiber (AR-HCF) in high-capacity and low-complexity Intensity Modulation/Direct Detection (IM/DD) short-reach optical interconnect systems. Following the logic of single-wavelength high-speed support

cross-band transmission validation

Wavelength Division Multiplexing (WDM) capacity expansion

and Dense WDM (DWDM) high-density capacity validation

this paper summarizes representative experimental progress in AR-HCF-based short-reach optical interconnects in recent years. It also analyzes its technical contributions in terms of the transmission channel

device packaging

modulation formats

and low-complexity digital signal processing. This review shows that AR-HCF extends the physical boundary for high-density DWDM transmission over the C+L bands in IM/DD systems by reducing dispersion and nonlinear impairments

thereby providing a low-complexity scaling path for terabit-class short-reach optical interconnects.
