Research on OLT Uplink Bearing Strategy Under the Background of Broadband Services Speed-up
With the continuous deepening of broadband gigabit construction,fixed broadband services have put forward higher require-ments to bearer networks in terms of bandwidth and network security.Some traditional bearer models have been unable to adapt to the development of services.Combined with the change of fixed network service and OLT uplink bearer demand,the existing problems of IPRAN bearer schemes are analyzed,and various bearer technology schemes including fiber,WDM,PeOTN,Smart-MAN are discussed and compared.The OLT uplink bearer and optimization strategy are proposed,which pro-vides a reference for standardizing access layer network and improving bearer efficiency.
