The IEP3100-4FT-4RS series of enhanced industrial grade ONU is a new generation of industrial-grade ONU introduced by EVERSHEN Technology. It is mainly used for distribution automation users in smart grid construction to meet the requirements of Gigabit Ethernet / RS232 / RS485 multi-service access demand. The IEP3100-4FT-4RS series supports the EPON specification and power industry equipment requirements of the power industry. The dual PON port design with flexible FPGA control provides RS232 / RS485 interface via DIP switch and programmable logic configuration, with unified software operating system Can provide users with rich business features for smart grid construction in the distribution network automation data communication platform.

Main advantage

1. Strong and flexible networking model. The IEP3100-4FT-4RS adopts the "hand-held" full protection switching type high reliability topology, the 1 + 1 protection function of the power network communication link and achieves less than 50ms protection switch to ensure the reliable operation of the power network communication system. In addition, according to the actual distribution of different network structure, you can also use a flexible tree, chain hand handle, ring and other structures.

2. EPON passive optical transmission network. Fiber as a transmission medium, transmission full passive, reliable and stable operation. To achieve single-fiber bi-directional high-bandwidth business carrying, up and down to 1.25Gbps. EPON network support multi-level spectral bus-based architecture, in line with distribution network transmission line structure.

3. To provide multi-service QOS protection. Supports QoS mechanisms based on ITU-T Y.1291, including marking priority, queue scheduling, traffic policing, congestion suppression, cache management, and so on. The system supports different delay and jitter for different users and services, guarantee the bandwidth and maximum bandwidth. The system supports DBA mechanism, allocates and limits the upstream bandwidth of each ONU.

4. Advanced product architecture. Product modular design, support a variety of custom needs, dual power supply, safe and reliable, and can be based on customer needs to provide AC 85 ~ 265V, DC 12 ~ 36V and so on.

5. Rich Ethernet function. With the effective isolation protection mechanism, VLAN isolation, protection port, MAC address binding, IP address binding, port speed limit, queue technology, flow control technology for the development of multi-service integration has played a technical guarantee, smooth upgrade capacity expansion.

6. Unified and comprehensive network management system. Oriented business, providing a unified network transmission and interconnection protocol, address management, domain name management, security management, user access management. Rich OAM functions, including configuration, alarm, performance monitoring, fault isolation and security management, while supporting the CLI and GUI two management methods, easy to learn and use.

7. Industrial design for power systems. ONU with dual PON uplink, providing GEPON, FE, RS232 / 485 and other business interfaces. To meet the wide temperature -40 ℃ ~ 85 ℃, to adapt to a variety of harsh environments, anti-strong lightning and strong electromagnetic interference, in line with GB / T17626 electromagnetic compatibility 4 standard, CE safety requirements.
