Gigabit Loop Network Intelligent Optical

Overview

     Double loop self-healing gigabit Ethernet switch series products is high-performance embedded industry Ethernet self-healing loop switch, full line-rate 1000M redundant optical fiber loop network structure, can realize multi-point Ethernet interface optical loop network transmission and access. This equipment adopt LSI, high-integration optical device and DPLL (digital phase-locked loop) technology, small size, high reliability, support 256 optical fiber node, automatic cut down when failure, power-off, fiber-break and automatic throw-in when failure recovery (switching time less than 5ms).

      For the loop network of this equipment can transmit H.264 HD video signal with high-quality, and can transmit up to 300 routes accumulated, solve the problem of fiber resource wastes, network complex and high costs in traditional point-to-point video optical transmission. It is the preferred scheme of security protection, intelligent traffic, safe city, highway, railway, electric, financial, water conservancy, industry control optical network.

Main feature

◆ Adopt exclusive digital technology realize network-wide peer access, every site can free-configuration according users need and bring the most flexible of network to users.

◆ Exclusively design for electric power network distribution automation, industrial automation, traffic, telecom etc high-reliability data communication.

◆ Has 2 routes full line-rate 1000M redundant optical interface, user interface has 3 routes 10/100/1000 self-adapting Ethernet interface, support address learning and broadcast inhibition.

◆ The network-wide management can realize local management through serial ports and remote management through web mode, it can automatic generate network topology, to configure, inquire the switch in network, record and backup the journal and failure.
