What is the key function of a fiber cable in networking compared to other cables?

The key function of a fiber cable in networking is its ability to offer very high bandwidth. Fiber optic cables transmit data as pulses of light through strands of glass or plastic fiber, which allows them to carry significantly more data over greater distances compared to traditional copper cables. This higher bandwidth makes fiber optics ideal for applications that require fast and reliable data transfer, such as broadband internet services, video streaming, and telecommunications.

Moreover, the high bandwidth capacity of fiber cables supports the growing demand for data traffic in modern networks, accommodating multiple users and devices without a reduction in speed. This ability to handle large amounts of data simultaneously is a fundamental advantage of fiber technology over other types of cables, which typically offer lower bandwidth capabilities and can become congested more easily.

In summary, the superior bandwidth capacity of fiber optic cables sets them apart, making them the preferred choice for high-performance networking needs.
