Which statement is true regarding the number of fibers in a ribbon cable?

The statement that is true regarding the number of fibers in a ribbon cable is that it can have multiple fibers aligned in a flat ribbon. Ribbon cables are specifically designed to house many optical fibers closely packed together in a flat configuration, which allows for efficient use of space and simplifies the installation process.

The structure of ribbon cables enables them to support a wide variety of fiber counts, often ranging from a few fibers to dozens, depending on the application needs. This design enhances the ability to manage and route cables effectively and is particularly beneficial in high-density installations, such as data centers and telecommunications environments.

The other statements do not hold true for ribbon cables. They do not always include exactly two fibers, as they can contain many more. While ribbon cables can be used in multimode applications, they are not limited to them, as single-mode fibers can also be incorporated. Lastly, ribbon cables can indeed be used with MPO (Multi-Fiber Push-On) connectors, which are designed to accommodate multiple fibers simultaneously, aligning perfectly with the purpose of ribbon cables.
