Abstract

This paper discusses the key design issues in applying both CWDM (coarse wavelength division multiplexing) and optical hub technology to an access network. The purpose is to reconsider characteristics of both optical circuits (such as a splitter, a coupler, a laser diode, a photo diode) and CWDM technology, and to try to find improved optical components deployment in access areas. The core of the network is composed of optical components, i.e., optical hub and fibers. CWDM functionality (such as LD and PD) is provided by newly designed ONICs (optical network interface card) located at a station site. The proposed access network structure has advantages in simplicity and scalability. Test bed implementation is included.
CWDM接入网的光集线器网络设计
本文讨论了在接入网中应用粗波分复用和光集线器技术的关键设计问题。目的是重新考虑光电路(如分路器、耦合器、激光二极管、光电二极管)和CWDM技术的特性,并试图在接入区域找到改进的光元件部署。网络的核心是由光器件组成,即光集线器和光纤。CWDM功能(如LD和PD)由位于站点站点的新设计的ONICs(光网络接口卡)提供。所提出的接入网结构具有简单、可扩展性强等优点。包括测试平台的实现。
