Overview
IEC 62149-7:2012 is an international standard published by the International Electrotechnical Commission (IEC) that specifies performance standards for 1 310-nm discrete Vertical Cavity Surface Emitting Laser (VCSEL) devices. These fibre optic active components, of both transverse single-mode and multimode types, are primarily used in fibre optic telecommunications and optical data transmission. The standard applies to VCSEL chips mounted on substrates with wire bonding to their anode and cathode terminals, explicitly excluding devices with fiber pigtails.
This standard defines rigorous product performance requirements, including a comprehensive battery of tests and measurements, with precise conditions, severity levels, and pass/fail criteria. It ensures that VCSEL devices meet reliable operational benchmarks necessary for high-speed optical communication systems.
