Abstract: EPON is a good solution for FTTH. However, when a variety of services are transmitted on EPON, there still exsits a lot of challenges, such as QoS, DBA, high-bandwidth, safty, cost and so on. The industry-leading EPON chipset provider, Teknovus, provided a set of good EPON SoC solution, which can meet the low-cost multi-service integrated access EPON system design. It is bound to further promote the EPON technology.
