IDM-RACK3U Centralized Protocol Converter
The Centralized Protocol Converter adopts a 19-inch 3U front plug-in card structure. Each slot corresponds to one remote RS232/422/485 data optical terminal or single E1 bridge (optical modem), E1 optical terminal, high-speed serial optical modem, optical Ethernet switch, serial-to-bidirectional HDMI converter, telephone optical terminal, or E1 (V.35) optical modem, enabling convenient construction of a star network. The IDM-RACK3U Centralized Protocol Converter fully utilizes the abundant existing E1/fiber resources in telecommunications networks to extend the transmission distance and application scope of Ethernet, providing an optimal solution for Ethernet access. This product can be used in various fields such as LAN interconnection, video-on-demand, and remote surveillance.
