How many types can optical fiber cable be categorized into?

Optical fiber cables can be categorized primarily into two main types: single-mode and multimode. Single-mode fiber is designed for long-distance communication, allowing light to travel directly down the fiber with minimal reflection, thus enabling higher bandwidths over longer distances. In contrast, multimode fiber has a larger core and allows multiple modes of light to propagate, making it suitable for shorter distances as the light can reflect off the walls of the core.

While there are variations based on specifications and applications, the fundamental classification into single-mode and multimode is universally recognized in the telecommunications field. This understanding is crucial for electrical contractors as it impacts the choice of fiber for specific installations and projects. Given this classification, it becomes evident that two main types encapsulate the core differences in design and use of optical fiber.
