中文摘要：
光标记交换是一种光交换新技术，能有效克服光交换中的电子瓶颈，其技术关键是光标记的产生和提取。本文对新型副载波复用、载波抑制和分离、正交调制这3种光标记新技术进行了描述与讨论。并比较分析了各自的优缺点及实用化前景。
英文摘要：
Optical label swapping （OLS） is a new technology of optical switch, which can overcome electronic bottleneck effectively,The key technology of OLS is how to produce and erase optical label. This paper describes and discusses sub-carrier multiplexing, optical carrier suppression and separation, quadrature modulation technologies, compares and analyzes not only the strengths and limitations of these technologies, but also the vista of practical application.
