This series of products are Ethernet IEEE802.3 media converters. The equipment has 4 electrical Ethernet ports, of which 1，2 ports are Gigabit and 3，4 ports are 100M to achieve physical isolation. They can achieve bidirectional bandwidths of 1000M and 100M respectively, and the fiber distance (20/ 40/60/80/100 km), the total bandwidth is 1100M in both directions.
    Two Ethernet electrical ports have their own independent Gigabit and 100M bandwidths. Through a single optical fiber transmission, the Ethernet signals received by the opposite end are also completely independent, without mutual interference and mutual influence, that is, physical isolation.The equipment is based on the Ethernet switch chip + FPGA solution, with remote OAM frame management function, supports Console network management/SNMP network management, and can also be interconnected with 2U plug-in card type 1 optical 2 electrical transceivers with SNMP network management. It can be connected to SNMP software. Manage to this device.
