近年来,以太网无源光网络(EPON)深受运营商的青睐,因其结合了以太网和无源光网络两种技术的优势,成为宽带接入网的最佳解决方案之一。但随着高带宽业务发展,如高清电视(HDTV)、视频会议等,传统的EPON技术在满足用户对带宽的需求这一方面显得无能为力;迫切需要新一代EPON技术一10G EPON,10G EPON-不仅传承了1G EPON的优点,而且带宽提高了10倍。但是,并非所有的接入网都需要升级为10G光纤链路,因为不同用户对于带宽的需求是不同的,因此1G EPON和10G EPON共存模式将在一段时间内长期存在。
In recent years, Ethernet Passive Optical Network (EPON) by operators of all ages, because it combines the advantages of both Ethernet and passive optical network technology, broadband access network as one of the best solution. However, with the development of high-bandwidth services, such as HDTV and video conferencing, the traditional EPON technology is incapable of meeting the user’s demand for bandwidth. A new generation of EPON technology is urgently needed - a 10G EPON and a 10G EPON - not only Inherited the advantages of 1G EPON, and bandwidth increased by 10 times. However, not all access networks need to be upgraded to 10G optical links. Because different users have different bandwidth requirements, the 1G EPON and 10G EPON coexistence models will last for a long time.
