4ETH Physical lsolation Fiber Modem （Bandwidth 2M）

This interface converter is based on FPGA. Multiplex 4Channel 10/100Base-T Ethernet interface to 1Channel Optical Fiber interface to provide users with Ethernet access at the rate of 1984K. It is widely used in finance, securities and security departments which need to be provided two different networks, and both on a physical network can be completely separated. For example, the financial system business network, internal office network and business network can’t be linked together. This interface multiplexer can solve this problem.

● Based on self -copyright  IC 

● Inter-set dynamic Ethernet MAC address (4,096) with local data frame filtering function

● 4Channel Ethernet rate is 1984Kbps, set up the first channel rate, the second channel Ethernet rate automatic allocation

● The local device can forced the remote device rate follow it

● The Ethernet interface supports jumbo frames (2036bit)

● Ethernet interface supports 10M/100M, half/full duplex auto- adaptable

● Ethernet interface supports AUTO-MDIX  (crossed line and straightly connected line self-adaptable )

● Have Ethernet monitor self-reset function, the equipment will not dead

● Support SNMP Network Management;

● Can form the structure: 4ETH Physical Isolation+E1 (A)－－-E1 Optical Fiber Modem(B)－－-this device (C)
