The "cRIO OPIF 25MBit/s" module is a powerful solution for optical communication over fiber optics (FO) in National Instruments Compact-RIO systems. It serves as an adapter module that facilitates the transition from electronic signals to optical transmissions, thereby ensuring reliable, high-frequency signal transmission over longer distances with minimal susceptibility to interference. 

Technical Description 

The module utilizes AFBR transmitter/receiver technology, which includes a 650-nm LED source with integrated optics and a driver IC. This technology ensures efficient coupling into 1-mm polymer optical fibers (POF). The receiver consists of an IC with an integrated photodiode that converts the optical signal into a logic-compatible output signal. 

The "cRIO OPIF 25MBit/s" module offers a high data rate of 25 MBit/s and utilizes “Versatile Link” technology to reliably transmit optical signals. It is equipped with 3 transmitters and 3 receivers that allow simultaneous signal transmission across multiple channels. The data rate of 25 MBit/s ensures fast and precise communication, which is required in various industrial applications. 

An example of software integration is available in LabVIEW, allowing the module to be easily integrated into existing Compact-RIO-based systems. With an optionally available adapter module, the product can also be used with the sbRIO family from National Instruments. 
This flexible connection and easy programming facilitate the use of the module in various applications.
