XDK-E8608T OLT series, which hashigh reliability, highly dense EPON access and robust switching and routingabilities, is a new generation of broadband and multiservice access OLT devicesoriented towards the service-integrated network. XDK-E8608TOLT includes three models: XDK-E8608T (8 PON ports, 8 GE uplink), All XDK-E8608TOLT products support power source redundancy. XDK-E8608T OLT can be widelyapplied on the networks of the carriers, EPON in the NGB upgrade of theBroadcast, TV and film system, or automatic power distribution, power-consumedinformation collection and PFTTH in the electric power industry. MainStrengths ? Abiding by IEEE802.3ah, XDK-E8608T OLT series meets relevant requirementsof GEPON OLT regulated in TechnicalRequirements of YD/T1475-2006—EPON and ChinaTelecom EPON Technical Requirements. ? XDK-E8608T OLT products are standalone devices with high density and optional10G uplink expansion, so they are easy for expansion and upgrade. ? XDK-E8608T OLT has L2/L3/L4 functions, supports 128Gbps backplanebandwidth, static routes, RIP, OSPF and so on. It supports advanced functionssuch as QoS, bandwidth control and multicast, adding extra values to the wholenetwork. ? This series of products has high reliability. The power source can bebacked up through the " 1+1" mode. At the same time, VRRP, STP and LACP providefurther reliability. ? A maximum optical coupling ratio of 1:64, up to 1024 ONUs and a 20km transmissiondistance. ? XDK-E8608T OLT supports various interface types including GE, TE and EPON. ? XDK-E8608T OLT series supports CTC2.0/2.1/3.0 wholly, automaticallydetects and works harmoniously with ONUs made by different manufacturers. ? It supports the RFC 1213 SNMP protocol.
