Avago Technologies provides solutions for industrial networking applications. Optocouplers are used to maintain data integrity, thereby eliminating group loop current and common mode noise. Avago Technologies offers customers value with multi-channel and bidirectional optocouplers, as well as a series of digital optocouplers that operate at both 3V and 5V. For longer runs, optical fiber-based solutions are ideal as the fiber can be run very close to EMI producing devices without compromising the data link. Industrial Ethernet protocols are becoming more widely used, including standards such as ProfiNet, Interbus, and EtherCat. It is likely that fiber optic based links and electrically isolated links using digital optocouplers will co-exist for some time, and Avago offers solutions for both choices.
