ZHOU Yu-xun, ZENG Qing-ji, LI Yu-feng, et al. The realization of fast self-healing protection of WDM all optical network: SHAONET[J]. 1999,(5):10-13. DOI: 10.13756/j.gtxyj.1999.05.003.
WDM all optical networks using wavelength routing represent the most promising solution for future high-capacity fiber networks. SHAONET
the first WDM all optical network testbed in China
is a metropolitan self-healing ring. A novel OADM having protection function is adopted. This paper presents the realization of fast self-healing mechanism using in SHAONET.
