3G HD-SDI + Serial/Dry Contact + Ethernet Fiber Mux

This product is a point-to-point multi-service optical transmission device that is developed on the basis of the special-purpose VLSI. This product provides 4 channels of 3Gbps HD-SDI video, 8 channels of dry contact interfaces/4 channels of RS232-422-485 interfaces; 2 channels of Fast Ethernet interfaces, and 2 channels of Gigabit Ethernet interfaces. 3Gbps HD-SDI high-definition digital TV optical transceiver signal format from 270Mbps to 2.97Gbps, supports SMPTE424M, SMPTE292, SMPTE344M, SMPTE259M and DVB-ASI (270M) and other digital TV format signals.

Each Ethernet is physically isolated and has its own independent 100M bandwidth; the total bandwidth of the 4 channels Ethernet is 2*1000M+2*100M=2200M, which is completely independent and physically isolated through an optical fiber transmission; Digital circuit, the whole machine works reliably and stably, with low power consumption, high integration, small size, and easy installation and maintenance.

● SD, HD, 3G input automatic detection, support 270Mbit/s – 1.48Gbit/s – 3Gbit/s rate; support new FULL HD 1080P/60HZ 3Gbps HD-SDI format signal, transmission distance up to 80KM; support SMPTE 424M(2.97Gbps/s), SMPTE 292M(1.485Gbps/s), SMPTE 344M(540Mb/s), SMPTE 259M(360Mb/s) and DVB-ASI(270Mb/s);

● With automatic cable equalization in the transmitter, 80M: 2.97Gb/s, 140M: 1.485Gb/s 250M: 270Mb/s;

● Both the transmitter and receiver have LEDs to indicate the access status of the SDI signal;

● 2 channels 100M Ethernet ports work in 100M full-duplex mode, each Ethernet electrical port has its own independent 100M bandwidth and is physically isolated;

● 2 channels Gigabit Ethernet 10/100/1000M, full/half duplex fully self-adaptive, each group has an independent 1000M bandwidth, physical isolation;

● Ethernet supports the transmission of VLAN super-long data packets, which can be matched with switch products that support the IEEE802.1Q protocol, and can support jumbo-frame Ethernet packets with a maximum packet length of 10240;

● It can be connected to 1-8 dry contacts or 1-4 RS232/422/485 serial interfaces;

● Various interfaces from radar protection to IEC61000-4-5 (10/700μS) Differential mode: 6KV impedance (40Ω); Common mode: 6KV, impedance (40Ω) standard;

● A variety of power supply options are available: AC220V, DC-48V/DC24V, etc.;
