Introduction
Fiber optic transmission offers the benefits of wide bandwidth, immunity
to EMI/RFI interference, and secure data transmission. ADAM-4541/
ADAM-4542 can be used as an RS-232/422/485 point-to-point or point-
to-mutipoint connection for transmitting and converting full/half-duplex
signals and their equivalents within a fiber optic environment. Fiber optics
is the perfect solution for applications where the transmission medium
must be protected from electrical exposure, lightning, atmospheric
conditions or chemical corrosion.
The ADAM-4541/4542 is specifically designed to link various machinery
equipped with an RS-232/422/485 communication ports (such as
computer systems or manufacturing machines). Using standard ST
connectors, the module's fiber optic ports can accommodate a wide range
of fiber optic cable sizes, including 62.5/125 (9/125) µm.
