WebMar 28, 2024 · FECC – Forward Error Correction (FEC) is a digital signal processing technique used to enhance data reliability. It does this by introducing redundant data, called error correcting code, prior to data transmission. FEC provides the receiving side with the ability to correct errors without a reverse channel to request the retransmission of data. WebOpus advanced data management solutions store all inspection data securely and generate reports and at-a-glance dashboards for easy administration.
