摘要
文章以电力通信业务的特点和需求为背景,通过讨论WDM所具备的与这些需求相符的高容量、低成本、易扩展三大优势,看电力通信系统发展WDM的必要性;通过对WDM技术分类(DWDM、CWDM)的详细论述,看WDM技术在经济性、实用性和灵活多样性方面将对电力通信系统产生的深远影响;从列举的WDM应用实例,看WDM技术在电力光纤通信网发展中的重要价值。此外,对WDM系统的构成、光电器件及分类等内容作了介绍。
Optical fiber communications used in electric power system are mostly based on SDH systems. In order to follow developmental steps of optical network, the advanced WDM technique can be used to satisfy requirement of transmission bandwidth. This paper analyzed applieation foreground of WDM technology used in electric power communication system. According to the characteristic and demand of electric power communication services, through discussing advantages of WDM system about high capability, low cost and easy expansibility, it is necessary to develop WDM system. Via discussed the sorts of WDM technique, its economy, practicability and variety will influence the electric power communication system. Via enumerated WDM applied examples, it has an important value in electric power optical communication network development. Finally, this paper introduced the configuration of WDM system, optical-electric elements and sorts.
