Advantech Industrial Automation's SC Type Fiber-Optic Industrial Media Converters
SC type fiber-optic industrial media converters for unmanaged EKI-3000 Ethernet switches include EKI-3541M, a multi-mode version to transmit data up to 2 km, and EKI-3541S, a single-mode version to send data up to 30 km. They transparently convert Ethernet signals to optical. The plug-and-play devices carry IP40 certification for light industrial usage. They have an operating voltage range of 12 to 48 Vdc and provide 3,000-Vdc surge (EFT) protection against overvoltage.
