The industrial grade 4-port ONU follows IEEE802.3ah and meets the relevant requirements for GEPON OUN equipment in "YD/T 1475-2006 Access Network Technical Requirements - Passive Optical Network (EPON) Based on Ethernet" and "China Telecom EPON Equipment Technical Requirements CTC2.0/2.1". At the same time, it complies with the main communication standard of the power industry, "Passive Optical Network (EPON) System Based on Ethernet", and relevant specifications of industrial level requirements in the security industry. Adopting network standards with good openness, wide application, and transparent and unified TCP/IP protocol, it can be widely used in the security monitoring industry.

Main advantages

1. EPON passive optical transmission network. Fiber optic, as the transmission medium, is passive throughout the transmission process and operates reliably and stably. Realize single fiber bidirectional high bandwidth service bearer, with up to 1.25Gbps uplink and downlink. The EPON network supports a bus architecture with multi-level splitting, which is in line with the distribution network transmission line structure.

2. Provide multi-service QOS guarantee. Support QoS mechanisms based on ITU-T Y.1291, including technologies such as tag priority, queue scheduling, traffic supervision shaping, congestion suppression, and cache management. The system specifies different SLA parameters such as latency and jitter, guaranteed bandwidth, and maximum bandwidth for different users and businesses. The system supports DBA mechanism to allocate and limit the uplink bandwidth of each ONU.

3. Advanced product architecture. Modular product design, supporting multiple customization requirements, safe and reliable, and can provide AC220V according to customer needs.

4. Rich Ethernet functionality. Having effective isolation and protection mechanisms, VLAN isolation, protection ports, MAC address binding, IP address binding, port speed restriction, queue technology, flow control technology, etc., provides technical support for the development of multi business integration and can smoothly upgrade and expand.

5. A unified and comprehensive network management system. Business oriented, providing unified network transmission and interconnection protocols, address management, domain name management, security management, user access management, etc. Rich OAM functions, including configuration, alarms, performance monitoring, fault isolation, and security management, while supporting CLI and GUI management methods, making it easy to learn and use.

6. For industrial grade design. Meet a wide temperature range of -40 ℃~85 ℃, be able to adapt to various harsh environments, resist strong lightning strikes and strong electromagnetic interference, and comply with GB/T17626 electromagnetic compatibility level 4 standards, CE safety regulations, etc.
