 +**FEC** on an SFP port refers to **Forward Error Correction (FEC)**, which is a technique used in fiber optic and Ethernet networks to enhance data transmission reliability by detecting and correcting errors without the need for retransmission.
 + 
 +**FEC (Forward Error Correction)**:
 +FEC is a mechanism that adds redundant information to the transmitted data. This redundancy allows the receiving end to detect and correct errors caused by signal degradation or noise during transmission.
 +
 +Purpose: FEC is essential for high-speed data links (e.g., 10G, 25G, 40G, 100G Ethernet) to improve link quality and performance.
 +
 +Types: Different FEC modes can be used depending on the standard and speed of the connection (e.g., Reed-Solomon FEC).
 +
 +
 +  *   **auto**   Enable FEC Auto-Neg
 +  *   **cl108**  Enable clause108 with 25G
 +  *   **cl74**   Enable clause74 with 25G
 +  *   **off**    Turn FEC off, FEC is mandatory for speeds 50G or higher
 +
 +
 +----
 +----
 +
 +
 +**Benefits of FEC on SFP Ports**:
 +
 +  * Error Correction: FEC can correct errors due to signal attenuation or interference.
 +  * Better Link Performance: Allows for longer cable runs or higher speeds by improving signal integrity.
 +  * No Retransmissions: Unlike other error correction methods, FEC works proactively without needing retransmissions, which is important for low-latency environments.
