Large Mode Area (LMA) fiber

Due to the very small core area in optical fibers, as the power contained is increased the power density can become high enough to induce non-linear effects and/or fiber damage. In order to reduce power density the mode area of some fibers is designed to be larger, while maintaining single-mode performance, by reducing the NA and increasing the core diameter. This means that higher powers can be handled before non-linear effects occur.
