What is typically the core diameter of multi-mode fiber?

Multi-mode fiber typically has a core diameter that ranges from 50 to 62.5 micrometers. This size allows multiple light modes to propagate through the fiber simultaneously, which is essential for applications that require high bandwidth over relatively short distances. The larger core diameter compared to single-mode fibers, which typically have a core diameter of about 8-10 micrometers, facilitates easier coupling of light into the fiber and allows for the use of less precise optical components. Therefore, 50 to 62.5 micrometers is the standard measurement for multi-mode fiber, as it optimally supports the multiple light paths necessary for effective signal transmission in various networking environments.
