EPON技术在宽带专线中的应用

相比较其他PON技术,EPON在技术成熟度和设备价格方面具有一定的优势,国内运营商已经开始进行EPON的试商用。EPON技术与传统接入技术相比具有节省投资、提高资源利用率、实现宽/窄带统一接入、接入方式灵活、高速带宽且分配灵活等优点。对宽带专线业务来讲,能减少业务侧数据设备的投资,实现全业务接入的同时,能够实现带宽的灵活调整,可以同时开展带宽共享及独享业务,实现专线业务的灵活配置。

Application of EPON Technology in Broad-band Dedicated Line

Compared with other PON technology,the technology of EPON has certain advantages in technical maturity and equipment price.Domestic operators have already started commercial EPON trial.Compared with other traditional access technologies,EPON can save investment,enhance the rate of resource utilization,enable unified access of broad and narrow band,increase the flexibility in access,and offer high speed bandwidth with flexible allocation.As for private line of broadband services,operational side data equipment investment can be reduced and full service access can be obtained.Meanwhile,the flexibility of bandwidth adjustment can be achieved,bandwidth sharing service and exclusive bandwidth service can be conducted simultaneously to achieve flexible configuration of Private line services..
