E1-4FE interface Converter JHA-CE1fF4p

      （Physical lsolation）

Overview

This interface converter is based on FPGA. Can realize 4Channel Ethernet data transmission over 1E1 circuits，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.
