This paper reviews optical fibre technology for local area optical communications systems. Technologies used in local systems include single and multimode fibre, single and multimode lasers, optical modulators, photodetectors, wavelength division multiplexing, multilevel modulation formats, electronic packet switching, electronic equalization and error correction. These methods have enabled the local area optical link data rate to increase from 0.1 Gb/s in 1990 to nearly a Tb/s in 2019. The challenges to increasing link data rates further, whilst reducing the transmitted power per bit, at reduced cost are discussed. Potential technical solutions and newly proposed methods which might address these challenges are highlighted.

局域光数据通信系统的进展

本文综述了用于局域光通信系统的光纤技术。本地系统中使用的技术包括单模和多模光纤、单模和多模激光器、光调制器、光电探测器、波分复用、多级调制格式、电子分组交换、电子均衡和纠错。这些方法使局域光链路数据速率从 1990 年的 0.1 Gb/s 增加到 2019 年的近 Tb/s。进一步提高链路数据速率、同时降低每比特传输功率、降低成本的挑战是讨论。强调了可能解决这些挑战的潜在技术解决方案和新提出的方法。
