I-2542-A - RS-232/422/485 to Single-Mode Fiber Optic Converter
by ICP DAS

The I-2542-A of single-Strand fiber Converters supports Wavelength Division Multiplexing (WDM) technology that allows two independent data communication channels to transmit and receive over one standard, single mode and fiber optic line. The module is for RS-232/422 point-to-point connections and RS-485 multi-drop applications which require a signal to be transmitted for distances of up to 15km, making it a perfect solution in applications where transmission must be protected from electrical exposure, power surges, lightning strikes or chemical corrosion.
