Product details
product description
This series of products is a point-to-point multi service optical transmission equipment developed on the basis of the dedicated ultra large scale integrated circuit developed by the company. This product provides 4 video channels and 1-8 telephone interfaces; 1-16 switch quantity interfaces/1-8 RS232-422-485 interfaces; 2 100Mbps Ethernet interfaces, 2 Gigabit Ethernet interfaces; Two 100Mbps Ethernet channels, each Ethernet port has its own independent 100Mbps bandwidth; Two Gigabit Ethernet networks each have independent Gigabit bandwidth, with a total bandwidth of 2200M for all four Ethernet networks. They are transmitted independently and physically isolated through a single fiber optic cable; 2 optical interfaces (capable of 1+1 optical backup), etc; The internal circuit of the device adopts fully digital circuits, ensuring reliable and stable operation, low power consumption, high integration, small size, and easy installation and maintenance.
Functional Features
Based on independent intellectual property rights of integrated circuits, the total bandwidth of fiber optic lines is 3.125G;
The transmission distance of the optical port without relay can reach 2-80 kilometers; Provide 1+1 optical port backup function and dual optical port backup function to ensure uninterrupted business operations;
The video interface supports PAL/NTSC/SECAM full standard compatibility, with studio level transmission quality;
Two 100M Ethernet interfaces operate in 100M full duplex mode, with each Ethernet port having its own independent 100M bandwidth physical isolation;
