E8604T complies with IEEE802.3ah and P.R.C intercommunication standard,YD/T 1475-2006, supports CTC20/2.1, automatically discovers and cooperates withONUs of different manufacturers.
E8604T OLT supports the symmetric uplink/downlink1.25Gbps PON transmission rate, efficient bandwidth usage and Ethernetservices, helping carriers to provide reliable services to their users.
Its coupling ratio, 1:64, and its support ofdifferent hybrid ONU networks minimize the carrier's investment.
E8604T has strong functions and QoS guarantee ,and supports SLA and DBA.
Main Advantages
E8604T is an optical network device seriesthat is suitable for the current market; one E8604T supports up to four EPONsystems, so it has the following advantages:
Ø EPON:E8604T supports IEEE802.3ah and PRCCommunity Industry Standard (YD/T 1475-2006).
Ø System'scapacity:Themodularized PON card of E8604T can support one to four EPON systemssimultaneously, up to 256 ONUs and the 1/64 coupling ratio.
Ø Uplink interface: Its flexible design supportsvarious MAN interface type groups. The optical ports or the electrical portsare selected according to network conditions.
Ø Device size: A 1U device occupies a little space and consumes little power,decreasing the function cost of the services.
Ø Protectingthe bus optical fiber:E8604T supports that the link can be automatically switched to protect theoptical fiber when trouble occurs in the optical fiber.
Ø Itis highly reliable and powered by two power sources.
MainCharacteristics
Ø It adopts the point-to-multipoint network topology,effectively collects separate Ethernet services and aggregates them on the MANnode. It connects the upper-layer devices through the GE interface and can beconnected to the existing network smoothly.
Ø The Dynamic Bandwidth Allocation (DBA) mechanismenables all users to share the 1Gbps bandwidth reasonably, guaranteeing areliable QoS.
Ø The Rapid Spanning Tree Protocol (RSTP) enables theredundant interconnection between OLT and backbone network.
Ø They support the IGMP multicast and efficientlyutilize the bandwidth. They support the multicast VLAN.
Ø It supports the broadcast of IPTV, voice and datasimultaneously.
Ø It has rich OAM functions such as configuration,alarm, performance monitoring, trouble isolation and security management. Atthe same time, it supports the CLI/GUI management, which is easy to use.
