Product Information

Product Description

Fiber optics transmission offers the benefits of wide bandwidth, immunity to EMI/RFI interference, and secure data transmission. ADAM-4541 can be used as an RS232/422/485 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.


  • Avoids lightning strikes and EMI/RFI interference
  • Prevents damage from electrostatic discharge
  • Stable and error-free data transmission
  • Automatic internal RS485 bus supervision
  • No external flow control signals required for RS485
