○ GPON passive optical transmission network

The GPON network supports a bus-type architecture and tree structure with multi-level optical splitting to meet the needs of various access environments. Using optical fiber as the transmission medium, the entire transmission process is passive, and the operation is reliable and stable. It realizes two-way high-bandwidth service carrying with a single fiber, supports uplink 1.244Gbps/downlink 2.488Gbps high broadband transmission. With GPON OLT equipment, it can achieve a splitting ratio of up to 1:128., the network coverage radius can reach 20KM.

○ Provide QOS guarantee for multiple services

Support QoS mechanisms based on ITU-T Y.1291, including marking priority, queue scheduling, traffic supervision shaping, congestion suppression, cache management and other technologies. The system specifies different SLA parameters such as delay and jitter, guaranteed bandwidth, and maximum bandwidth for different users and services. The system supports a DBA mechanism to allocate and limit the upstream bandwidth of each ONU.

○ Advanced product architecture

Supports 1 GPON interface and 4 10/100/1000Mbps RJ45 electrical ports. The product is modular designed to support a variety of customization requirements. It is safe and reliable, small in size and low power consumption. The product power supply supports built-in full-voltage AC100~ 240V input, fully covering the requirements of the access distribution network environment for equipment power supply.

○ Rich Ethernet functions

It has effective isolation guarantee mechanism, VLAN isolation, protected ports, spanning tree, ACL, QoS, security filtering, storm control, MAC address binding, IP address binding, port isolation, port speed limit, queue technology, flow control technology, etc. It provides a technical guarantee for the development of multi-service integration, making this ONU product have safe service carrying capabilities.

○ Standard OMCI network management system

Supports the standard OMCI defined by the International Telecommunication Union standard ITU-T, including configuration, alarm, performance monitoring, fault isolation and security management, as well as localized configuration, etc., and cooperates with OLT to achieve richer service control. For business, it provides unified network transmission and interconnection protocols, address management, domain name management, security management, user access management, etc. Rich OAM functions, including configuration, alarm, performance monitoring, fault isolation and security management, etc. It also supports CLI(Telnet) and GUI(web) management methods, making it easy to learn and use.
