      Product Description
          This series of products to provide industrial-grade 4*FE +4*100base-FX to 1*1000base-X conversion mainly for long-distance fiber optic network (20/40/60/80/100 km) transmission. share1000M bandwidth each channel can be set through the Console port (Ethernet interface for the exchange port can support VLAN division) that logic Isolation; 1 console port. 
      Functional Properties
      ◆ Industrial Ethernet series designed for harsh and harsh industrial environments;
       Equipment to provide 4*FE 4*100base-FX 1 Gigabit optical port an optional Console / SNMP network management port;
       Electrical interface (RJ45 interface) support 10 / 100M adaptive full / half duplex mode MDI / MDI-X automatic detection;
       Optical interface to support multi-mode dual-fiber single-mode dual-fiber single-mode single fiber three fiber transmission mode SC / ST / FC / LC interface optional;
       With broadcast storm protection balance flow isolation conflict detection error and crash from the reset function suitable for video transmission and other large flow data applications;
       Transceiver built-in 1MBits high-speed cache to avoid the IP camera in the monitoring screen rapidly changing the environment caused by the transmission screen stuck phenomenon;
       Support VLAN long packet transmission can support IEEE802.1Q protocol with the switch to use the product to support up to 10K bytes of Ethernet packets;
       Equipment for the Ethernet switch chip + FPGA program with remote OAM management frame function with 2U card with SNMP network management 1*GE optical transceiver card interconnection SNMP software can manage to the device; can also support the Console (CLI) /WEB/ independent SNMP network management;
       The network management real-time view and management of the local end and the remote Ethernet interface status and settings; equipment with power-down detection function can detect when the optical signal is lost when the peer device power or fiber unreasonable;
       Support a wide range of 9-55V AC and DC power input;
       Support internal isolation redundant dual power input;
       Power supply support overload protection anti-reverse protection;
       Meet the requirements of industrial four electromagnetic compatibility;
       Super lightning protection function: anti-lightning anti-sensor high pressure anti-surge etc .;
       No fan efficient cooling reduce repair time;
       Anodized aluminum alloy shell IP40 protection class able to withstand the harsh environment of the test;
       Rail or wall mounted;
       Wide temperature type: Operating temperature -40 ℃ ~ +85 ℃;
       All models are tested by 100% roasting machine the warranty period: 5 years;
