Overview
IEC 62148-17:2023 is an international standard published by the International Electrotechnical Commission (IEC), focusing on the physical interface specifications for fibre optic transmitter and receiver components equipped with dual coaxial RF connectors. This latest 2023 edition replaces the original 2013 edition, providing a technical revision that aligns with evolving industry practices and connector technologies. The standard defines consistent package designs, electrical interfaces, and electromagnetic compatibility (EMC) requirements for enhanced interoperability and reliability in fibre optic communication systems.
Key Topics
- Dual Coaxial RF Connectors: Specifies the use of dual coaxial connectors for both transmitter and receiver components, including detailed assignments for electrical terminals.
- Physical Packaging: Defines the package outline and recommended printed circuit board (PCB) footprint layouts to ensure uniform assembly and integration.
- Electrical Interface: Details electrical terminal numbering, function definitions, and the application of SMPM (sub-miniature push-on miniature) connectors as per IEC 61169-60.
- Electromagnetic Compatibility: Mandates EMC compliance in alignment with IEC 61000 series to ensure components meet emission and immunity standards.
- Normative References: Incorporates references to related IEC standards such as IEC 61754 for fibre optic connector interfaces, IEC 62007-1 for optoelectronic device terminology, and replaces the withdrawn IEC 60874-1.
- Classification: Categorizes the components as type 7 following IEC 62148-1 specifications for active fibre optic devices.
