The optical module coding acts as a digital fingerprint that is inscribed into each transceiver's EEPROM—a memory chip. This fingerprint reveals important information including speed rating, wavelength, supported distance, and power levels. Integrated circuits and reference designs help you create a smaller and faster optical module design used in high-bandwidth data communication applications.

The SFF-8024 standard, maintained by the Small Form Factor (SFF) Committee, provides a unified framework of Transceiver ID and Management Codes. These codes allow host devices to correctly identify, configure, and manage a wide range of pluggable modules—including SFP, SFP+, QSFP, OSFP, and SFP-DD. This guide introduces how to read optical module information when it is installed on a network card in a Linux system.
