Description :

This series of products is a point-to-point multi service optical transmission equipment developed on the basis of the special VLSI developed by the company.


This series of products is a point-to-point multi service optical transmission equipment developed on the basis of the special VLSI developed by the company. This product provides 4 channel video, 1-8 channel telephone interface, 1-16 channel dry contact / 1-8 channel rs232-422-485 interface, 4 channel Gigabit Ethernet interface (sharing 1000m bandwidth), which is transmitted through one optical fiber, 2 optical interfaces (can be 1 + 1 optical backup), etc.; the internal circuit of the equipment adopts full digital circuit, which is reliable, stable, low power consumption, high integration, small size and easy to use Installation and maintenance.



Integrated circuit based on independent intellectual property rights, the total bandwidth of optical fiber line is 1.5g;

No relay transmission distance of optical port can be up to 2-120 km; 1 + 1 optical port backup function is provided, and double optical port backup function ensures uninterrupted service;

The video interface supports PAL / NTSC / SECAM full system compatibility and broadcast level transmission quality;

4channel Ethernet is 10 / 100 / 1000m, full / half duplex fully adaptive, and each Ethernet port supports auto mdix (Cross / direct connection adaptive);

100M Ethernet supports the transmission of VLAN ultra long packets, which can be matched with the switch products supporting IEEE802.1Q protocol, and can support the mega frame Ethernet packets with the maximum packet length of 10240;

1-8channel voice access, supporting call display function / reverse polarity billing / fax function; voice port supports FXO / FXS / two four wire EM / two four wire audio / magnet telephone interface, FXO port is connected with program-controlled exchange, FXS port is connected with the user’s telephone;

1-16 channel dry contactor 1-8ch RS232 / 422 / 485 serial interfaces can be connected;

One console management interface and one SNMP management interface can be selected;

All kinds of interface lightning protection meet iec61000-4-5 (10 / 700 μ s) differential mode: 6kV impedance (40 Ω); common mode: 6kV, impedance (40 Ω) standard;

A variety of power modes are available: AC220V, dc-48v / DC24V, etc.; it supports AC + DC, AC + AC, DC + DC and other dual power modes.
