摘　　要：本文从便于管理的角度对引入光层的光传送网重新进行了分层，并将光层进一步分为光通道层、波长复用段层和多波长放大段层。文中定义了光层中各子层的功能，并对各层中遇到的问题给出了解决方案。根据光层中故障的特点，提出了光层中各子层的性能监测和保护机制的要求和实现方案。最后，按电信管理网的概念和结构，结合光层的特点，设计了光层管理系统结构。A new layering structure of photonic transport networks is presented after the photonic layer is introduced in the transport network. The photonic layer is layered again into three sublayer:photonic path layer, wavelength multiplexing section layer, and multiwavelength amplifier section layer. The functions of each layer is definded and problemes in each layer is overcomed. The supervisory systems and protection schemes of each sublayer is presented according to the characteristics of faults in the photonic layer. Based on the concept and structure of telecommunication management network(TMN), the management system of photonic layer is designed.
