    EP2500-04S is the Shenzhen EVERSHEN Technology Co., Ltd. introduced a small-scale EPON access to the application of the scene of the miniaturized box OLT equipment. The EP2500-04S features a 1U 19-inch standard case and four fixed PON ports, with high reliability, low cost, ease of use and flexible deployment.

     EP2500-04S built-in powerful switching module to support full-service Gigabit wire-speed forwarding, support for the rich Layer 2 protocol; support command line, SNMP and other management;

     EP2500-04S maximum support 1:64 split ratio of 256 ONU access, coverage of 20KM, generally deployed in the central office room, resident cell room, directly with the user installed at the ONU through the ODN network. According to different user scenarios, the product can meet the FTTB, FTTC, FTTH and other applications of access occasions, operators are low investment in the construction of EPON access network the best choice.


    ☆ Small, low cost, flexible deployment

    EP2500-04S fixed configuration of four PON ports, each PON port supports maximum 1:64 split ratio, the machine supports up to 256 ONU access; the maximum transmission distance of 20KM (not higher than 1:32 spectacular); EP2500- 04S with 1U 19-inch box-type structure, small size, environmental adaptability, suitable for deployment in the ONU access density is not high and small networks.

    ☆ Second floor convergence exchange

    The EP2500-04S has a powerful Layer 2 switching module that supports full-service Gigabit wire-speed forwarding and supports a rich Layer 2 protocol. 8 Gigabit uplink, 4 optical 4 power configuration, support port VLAN, selective QinQ, port aggregation, for operators to provide a variety of flexible choice;

    ☆ QOS protection

    The OLT unit of EP2500-04S adopts the DBA dynamic bandwidth allocation function based on hardware, which is reliable and efficient. The system supports multiple ONUs with multiple LLIDs. Multiple priority queues can be configured in the upper and lower directions to ensure that the highest priority QoS service is guaranteed.

    ☆ Rich OAM function

    The EP2500-04S supports ONU auto-discovery, auto-registration, and supports automatic loopback testing on a single link. It supports port-based, protocol-based VLANs, supports IGMP proxy, snooping, port-based ACL packet filtering, and packet classification , Port-based traffic control, traffic shaping and other rich operational, manageable features.

    ☆ management function

    Support local command line management, SNMP management;

    Support in-band, out-of-band network management;

    ☆ easy to install, easy to maintain, plug and play

    EP2500-04S is simple and easy to use. By default, the device can be powered on normally. The ONU is automatically registered without additional configuration. After the device is deployed, the device can be monitored and the necessary service configuration is performed through the remote management platform.
