EPON OLT LE8（8*EPON+4*GE+4*10G SFP+）

Overview    LE16 is a high-density 1U box EPON OLT series. It uses the industry-leading commercial chip to fully support the IEEE802.3ah EPON technology standard and meets the EPON OLT equipment requirements of YD/T 1945-2006 Technical requirements for access network. It can realize ONU hybrid networking of different manufacturers and has good interoperability. The LE16 system has good stability and high reliability. It supports multiple management modes such as CLI, WEB & SNMP. The graphical management interface is clear, friendly and easy to use. LE16 provides 16 downstream EPON ports,4*1000Base-T up-link ports and 4*10GE optical SFP+ up-link ports, The SFP+ port with an expansion function, which can adapt to 1GE SFP or 10GE SFP+.LE16 adopts the industrial advanced technology, with powerful Ethernet services and QoS feature.it is suitable for Broadcast three in one, video surveillance network, enterprise LAN, Internet of Things, etc. Each EPON port supports Up to 1:64 Split ratio, total up to 1024 EPON users, supporting different types of ONU in different networks, minimizing operators' investments. The 1U height can be easy to install and maintain. It is an excellent choice for operators to quickly deploy FTTH networks. Features         ● Applicable to county and town level fiber optic network access and monitoring transmission, meets FTTH requirements to provide complete access to IP telephony, broadband data, IPTV, etc.
        ● System Structure: Provide 16 downstream EPON ports,4*1000Base-T up-link ports and 4*10GE optical SFP+ up-link ports.
        ● The SFP+ port with an expansion function, which can adapt to 1GE SFP or 10GE SFP+.
        ● System Capacity: 1:64 split ratio, full configuration supports up to 1024 EPON terminals.
        ● Up-link Interface: Flexible design supports multiple types network interfaces, optical or electrical interfaces optional based on network conditions.
        ● Supports dual power supply.
        ● 1U device takes small space, low power consumption, which reduce the total cost. Product Features
