The equipment is safe, stable and reliable, creating a rock-solid industrial IoT Internet of Things that is suitable for continuous operation in the industrial communications field.

Application fields: military control, industrial automatic control, traffic control, video control, distributed data acquisition systems, power acquisition and control systems, intelligent communities, safe cities, highway toll systems, etc.

○ EPON passive optical transmission network

EPON networks support multi-level optical splitting bus-type architecture and tree structure to meet the needs of various access environments. Using optical fiber as the transmission medium, transmission is passive throughout the entire process, and operation is reliable and stable. It realizes two-way high-bandwidth service carrying by single fiber, with upstream and downstream reaching 1.25Gbps.

○ 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 EPON interface and 4 10/100/1000Mbps RJ45 electrical ports. The product is modular designed to support a variety of customization requirements. It has dual power supply redundant power supply, safe and reliable, small size and low power consumption, and electromagnetic compatibility reaches Level 4 standards. The full AC voltage is 100-240V~ power input, which comprehensively covers the requirements of the industrial distribution network environment for equipment power.

○ Rich Ethernet functions

It has effective isolation guarantee mechanism, VLAN isolation, protected ports, MAC address binding, IP address binding, port speed limit, queue technology, flow control technology, etc., which provides technical guarantees for the development of multi-service integration and enables smooth upgrades and expansion.

○ Unified standard network management system

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 and GUI(web) management methods, making it easy to learn and easy to use.
