摘要
光纤接入网的网络结构有单一星型、双星型(包括有源和无源)和环型,而环型结构中又包括环型+大楼综合布线和环型+星型+引入线。鉴于客户的经济承受能力,应充分利用现有的铜轴电缆和双绞线,结合光纤媒质来实现宽带接入网。
The structure of optical access network includes single-star,double-star in-cluding active and passive and ring,while the ring structure includes ring+building cabling and ring+star+leadin.Con sid ering customers' economical capability,the existed cables and twisted-pairs should be made full use in combination with optical cable to re-alize broad-band access network.
