However, the exponential growth in data demand has positioned fiber optic technology as the superior alternative for performance, scalability, and future-readiness., 10G/25G/40G/100G and beyond depending on optics and reach). Copper Ethernet scales too, but practical limits are lower and depend. The two main options are fiber optic cables and copper cables, each with its own advantages and drawbacks. Fiber optic cables are praised for their high performance and scalability, while copper cables remain a cost-effective choice, especially for budget-conscious projects and older systems. Copper wire is more susceptible to interference and has limited data capacity, making optical fiber the preferred choice for modern high-speed. Optical connectivity, utilizing fiber-optic technology, has emerged as the superior choice for modern networking, offering unparalleled performance, reliability, and scalability. For example, a typical 10 Gbps copper Ethernet link (such as Cat 6A) over 100 meters can consume approximately 5 to 8+.
