Gepon FTTH OLT optical network device 4 pon port EPON OLT

Product Description

Main Advantages
    E***4T is an optical network device series that is suitable for the current market; one E***4T supports up to four EPON systems, so it has the following advantages:

• Ø       EPON: E***4T supports IEEE**2.3ah and PRC Community Industry Standard (YD/T ********6).
• Ø       System’s capacity: The modularized PON card of E***4T can support one to four EPON systems simultaneously, up to **6 ONUs and the 1/*4 coupling ratio.
• Ø       Uplink interface: Its flexible design supports various MAN interface type groups. The optical ports or the electrical ports are 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       Protecting the bus optical fiber: E***4T supports that the link can be automatically switched to protect the optical fiber when trouble occurs in the optical fiber.
• Ø       It is highly reliable and powered by two power sources.

Main Characteristics

• Ø       It adopts the point-to-multipoint network topology, effectively collects separate Ethernet services and aggregates them on the MAN node. It connects the upper-layer devices through the GE interface and can be connected to the existing network smoothly.
• Ø       The Dynamic Bandwidth Allocation (DBA) mechanism enables all users to share the 1Gbps bandwidth reasonably, guaranteeing a reliable QoS. 
• Ø       The Rapid Spanning Tree Protocol (RSTP) enables the redundant interconnection between OLT and backbone network. 
• Ø       They support the IGMP multicast and efficiently utilize the bandwidth. They support the multicast VLAN.
• Ø       It supports the broadcast of IPTV, voice and data simultaneously.
• Ø       It has rich OAM functions such as configuration, alarm, performance monitoring, trouble isolation and security management. At the same time, it supports the CLI/GUI management, which is easy to use.
