Composite cables that contain both optical fibers and electrical conductors are useful for what primary purpose?

Composite cables that contain both optical fibers and electrical conductors serve the primary purpose of improving data transmission. The inclusion of optical fibers allows for the transfer of data at high speeds and over long distances without the signal degradation often associated with electrical conductors. This is particularly beneficial in environments where large amounts of data need to be sent swiftly and reliably, such as in telecommunications and data centers.

The presence of electrical conductors in the same cable allows for the transmission of power and traditional electrical signals alongside high-speed data communication, which can streamline installations and reduce the overall complexity of wiring systems. Therefore, while composite cables can indeed help with installation efficiency and potentially lower costs, the main advantage lies in their ability to enhance data transmission capabilities. This makes them particularly advantageous in applications requiring consistent and rapid communication.
