随着我国宽带网络建设的深入推进,光纤接入网技术也在不断向前发展。目前光纤接入网主要采用EPON或GPON,上下行均工作在单一波长,这种在单一波长上为每用户分配时间片的机制,一定程度上限制了每用户的可用带宽,同时没有很好
With the deepening of China’s broadband network construction, optical access network technology is also constantly moving forward. Currently, the optical access network mainly adopts EPON or GPON, and both the uplink and the downlink work at a single wavelength. This mechanism for allocating time slices per user on a single wavelength limits to a certain extent the available bandwidth per user and is not very good
