Which of the following technologies is considered broadband?

Broadband refers to high-capacity transmission techniques that enable a large amount of data to be sent over various mediums. Fiber optic cable is considered broadband because it uses light to transmit data at incredibly high speeds over long distances, significantly surpassing the capabilities of traditional copper-based technologies such as twisted pair cables and Cat5 cables.

Fiber optics can support diverse types of data communications, allowing multiple signals to be sent simultaneously, which is a defining characteristic of broadband technologies. This capability makes fiber optic cable an essential component in modern high-speed internet services.

In contrast, twisted pair cables, while they can support internet connections, typically provide lower bandwidth and are primarily used for telephone and standard data communication. Serial cables are even less suitable for high-speed data transfer, as they transmit data one bit at a time, making them unsuitable for broadband applications. Cat5 cables, like twisted pair cables, can facilitate higher speeds than older technologies but do not match the performance and capabilities of fiber optic cables in the broadband domain.
