The STF-300C built by Antaira Technologies extends RS-232 or RS-422/485 serial data transmission to distances from 2 km to 80 km over s multi-mode, single-mode or WDM fiber optic connection. The converter is equipped with multiple interface circuits to adapt to RS-232, RS-423 or RS-422/485/ (2 or 4 wire) protocols. The STF-300C transmits up to 256 kbps for RS-232 or up to 1024 kbps for RS-422/485.
