cRIO OPIF 20MBit/s

The “cRIO OPIF 20MBit/s” module is a powerful solution for optical communication over fiber optic cables in National Instruments CompactRIO systems. It serves as an adapter module that converts electronic signals to optical transmission, ensuring reliable, high-frequency signal transmission over longer distances with minimal susceptibility to interference.

Technical description

The module uses HFBR transmitter/receiver technology with a wavelength of 820 nm.

The components offer excellent coupling efficiency and are compatible with a wide variety of fiber types. This technology ensures efficient coupling in fiber optic systems – Plastic-Clad Silica (PCS).

It is equipped with 2 transmitters and 2 receivers that enable stable communication over fiber optic cables. The module supports data rates of up to 20 MBit/s (without static signaling) and is compatible with widely used industrial connectors such as SC, ST and SMA.

Thanks to the 820 nm Miniature Link Series, a cost-effective, high-performance solution for optical communication, the module can establish reliable links over several kilometers.

With an example of software integration in LabVIEW, the modules can easily be integrated into CompactRIO-based systems, increasing their flexibility and adaptability in industrial applications.
