Optical fiber is a kind of electromagnetic wave. The basic structure of optical fiber is divided into three types: 62.5/125, 50/125, 9/125, where 62.5, 50, 9 refer to the core diameter of the optical fiber, which is the diameter of the main light transmission part, and 125 refers to the core diameter of the optical fiber. Is the cladding diameter of a conventional optical fiber.

Simply put, the outer diameter of the fiber optic cable generally has a certain specification, and there is no need to calculate it. Fiber hope fiber optic cable and patch cord manufacturers can provide high-quality fiber optic cables,fiber pigtails, fiber patch cords, single-mode multi-mode fiber, welcome to inquiry!
