GPON OLT L8(8*PON/4*GE/4*10G SFP+)


Overview        L8 is a high-density 1U box GPON OLT series. It uses the industry-leading commercial chip to fully support the ITU-T G.984.x and ITU-T G.988 GPON technology standard. It can realize ONU hybrid networking of different manufacturers and has good interoperability. The L8 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. L8 provides 8 downstream GPON ports,4*1000Base-T up-link ports and 4*10G optical SFP+ up-link ports, The SFP+ port with an expansion function, which can adapt to 1GE SFP or 10GE SFP+.L8 adopts the industrial advanced technology, with powerful Ethernet services and QOS feature, supporting SLA and DBA. The splitting ratio up to 1:128, 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 8 downstream GPON 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: 1:128 split ratio, full configuration supports up to 1024 GPON 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
