同步时分环形光纤综合业务网

A Synchronous TDM Loop Optical Fiber IBDN For Multiservice

同步时分环形光纤局部网,采用光纤双环,应用有源-无源混合式光存取访问及光开关等技术,使网络运行具有旁路、返回及网络拓扑重建等特点,网络运行的安全可靠性大大提高。网络介质访问采用时分多路访问(TDMA)方式,在控制器控制下,可获得点一点、环形、一点对多点的通信方式。网络运行软件支持各种通信方式。预计环形光纤网技术将可能提供一个性能优秀的宽带多种业务的局部网。

In synchronous Time-Division Loop optical fiber IBDN applying double optical fiber loop and active-passive optical accesses, the operation reliability of the optical fiber IBDN was increased by adopting of pass-by, look back and topology rebuilding of the network. Because TDMA was applied in controling of the network, the communi- cations of point to point, ring shap and multicast may be abtained.
