FEC is an effective digital signal processing method that improves the bit error rate of communication links by adding redundant information (parity bits) to the data at the transmitter side so that the receiver side then uses the redundant information to detect and correct errors. FEC is an effective digital signal processing method that improves the bit error rate of communication links by adding redundant information (parity bits) to the data at the transmitter side so that the receiver side then uses the redundant information to detect and correct errors. In this white paper, you will learn how FEC works, the trade-offs involved, and how we apply FEC in Cisco equipment. You will come away with a basic understanding of how FEC is used to optimize the performance of your network. What are transmission errors? A transmission error occurs when a bit. FEC, short for Forward Error Correction, is a technology used for detecting and correcting errors in data transmission. Simply put, it allows the receiving end to correct errors in the transmission without the need to resend data. To fully leverage the capabilities of FEC, however, it is essential. • Goal of this presentation is to show the FECi performance data measured on the actual 4x200G-PAM4 Optical Modules for field deployment and the benefit of FECi- providing additional Link budget margin required by the Network operators for their operational efficiency @ scale.
