Optisk multimodefiber med nedsænket gradientindeks

摘要

The present invention relates to a special multi-mode optical fiber (multimode fiber or MM fiber or fibre). In fiber optics, a graded-index or gradient-index fiber is an optical fiber whose core has a refractive index that decreases with increasing radial distance from the fiber axis. The present invention relates to a graded index multi-mode optical fiber, specifically to a depressed graded index multi-mode optical fiber.
