Comparison of Optical Access Solutions for VIP Clients<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> 孙曙和 Sun Shuhe Abstract
Three competitive optical access solutions in FTTP field are compared in the thesis, which are MSTP and RPR based on SDH, EPON and multi-service network optical transceiver(star topology optical device combining TDM and Ethernet service on transmission layer). And the conclusion that EPON and multi-service network optical transceiver are suitable solutions for most VIP clients in FTTP application is drawn. 近年来,网络运营商在经历了对用户驻地网的冷静思考之后,企业级大用户(下面简称大用户)由于其业务量大、服务需求旺盛而日益受到运营商的重视。传统的大用户接入是基于原来的PSTN网络,物理介质一般是双绞线。由于光纤接入有更好的扩展性和质量保证,因此逐渐成为大用户接入技术的主流。这里所说的用户光纤接入是指运营商一直将光纤接入用户驻地(FTTP),即运营商网络最末端的设备是光纤传输设备。 |
