BSIT200 - Week 8 Posting - Unraveling the Different Ethernet Physical Technologies

Ethernet, a critical element of modern networking, encompasses various physical layer technologies that enable the transmission of data across local area networks (LANs). These technologies include twisted pair Ethernet, which uses cables with twisted wires. There are two kinds: unshielded twisted pair (UTP) and shielded twisted pair (STP). UTP is cost-effective and commonly used in homes and offices, while STP is more suitable for environments with high electrical noise, such as industrial settings.

Fiber optic Ethernet is another essential type that transmits data using light through glass or plastic fibers. It offers high-speed data transmission and is immune to electromagnetic interference, making it ideal for long-distance communications and high-bandwidth applications. Additionally, there is coaxial cable Ethernet, which, although less prevalent today, is proficient at delivering high-speed internet and television services due to its ability to carry substantial data with minimal signal loss. Understanding these distinct Ethernet physical layer technologies is crucial for selecting the most suitable option based on specific requirements and environmental factors.
