Overview
IEC 62148-19:2019 is an international standard established by the International Electrotechnical Commission (IEC) that focuses on fibre optic active components and devices, specifically relating to package and interface standards. This Part 19 document defines the physical requirements for photonic chip scale packages (CSPs) used in optical transmitters and receivers. The primary goal is to promote mechanical interchangeability of photonic components by specifying a standardized physical interface and package outline.
Photonic chip scale packages are crucial in the rapidly evolving field of silicon photonics and fibre optic communication, offering compact integration and high performance. IEC 62148-19:2019 ensures manufacturers and users have a common reference for design, enabling seamless integration and replacement of optical modules within systems.
