光码分复用(OCDM)系统在光域对各路信号进行光编/解码,对用户数据进行全光信号处理,但是用户数目受到光标签数量的限制。光分组交换技术具有高速率、对数据速率和格式透明等优点,更能适应快速变化的网络环境,但存在光标签的提取、更新和竞争的难题。介绍了一种新型的基于WDM(波分复用)和OCDM的光分组交换系统,结合了光码分多址(OCDMA)技术和光分组交换(OPS)技术的优点,既扩展了系统用户容量又避免了对标签进行电域的处理,实现了数据的全光交换。
Optical Code Division Multiplexing (OCDM) system in the optical domain of each signal optical encoding / decoding, the user data for all-optical signal processing, but the number of users by the number of optical labels limit. Optical packet switching technology has the advantages of high speed, transparent data rate and format, and more adapt to the rapidly changing network environment, but there is the problem of light tag extraction, updating and competition. A new optical packet switching system based on WDM (wavelength division multiplexing) and OCDM is introduced. Combining the advantages of optical code division multiple access (OCDMA) technology and optical packet switching (OPS) technology, both the system user capacity Avoid the label of the electric field processing, to achieve the full optical data exchange.
