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 4ch video and 1-8ch telephone interface; 1-16 channels of dry contact interface / 1-8 channels of rs232-422-485 interface; 2 channels 100M Ethernet interface and 1 channel Gigabit Ethernet interface; 2 channels 100M Ethernet, each Ethernet port has its own independent 100m bandwidth; 1-channel Gigabit Ethernet, each channel has independent Gigabit bandwidth, and the total bandwidth of all 3-channel Ethernet is 1200m, which is completely independent and physically isolated through one optical fiber; 2 optical interfaces (1 + 1 optical backup) etc.; the internal circuit of the equipment adopts all digital circuits, which makes the whole machine reliable and stable, low power consumption, high integration, small volume and easy to install and maintain.



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

integrated circuit based on independent intellectual property rights, with a total bandwidth of 3.125g;

the optical port has no relay, and the transmission distance can reach 2 ~ 80km; Provide 1 + 1 optical port backup function, and double optical port backup function to ensure uninterrupted business;

the video interface supports PAL / NTSC / SECAM full system compatibility and studio level transmission quality;

two 100M Ethernet interfaces work in 100m full duplex mode, and each Ethernet interface has its own independent 100m bandwidth physical isolation;

1channel Gigabit Ethernet 10 / 100 / 1000m full / half duplex fully adaptive, each group has independent 1000m bandwidth physical isolation;

100M Ethernet supports the transmission of VLAN ultra long data packets, which can be connected with IEEE802 The switch products of 1q protocol are matched and can support giant frame Ethernet packets with a maximum packet length of 10240;

1-8chvoice access, support caller ID function / reverse polarity billing / fax function; The voice port supports FXO / FXS / two or four wire EM / two or four wire audio / magnet telephone interface. The FXO port is connected with the SPC exchange, and the FXS port is connected with the user’s telephone;

it can be connected to 1-16 channels of dry contactor 1-8 channels of RS232 / 422 / 485 serial interface;

one console management interface is optional; 1 SNMP management interface;

the lightning protection of various interfaces shall reach iec61000-4-5 (10 / 700) μ S) Differential mode: 6kV impedance (40 Ω); Common mode: 6kV, impedance (40 Ω) standard;

multiple power supply modes are available: AC220V, dc-48v / DC24V, etc; Support AC + DC; AC+AC; DC + DC and other dual power modes.
