Coaxial Cable (T-Connection): The Trailblazer of Networking

Let’s step into our time machine and travel back to the early days of networking, when the Coaxial Cable, or T-Connection, was the star of the show.

The Dawn of Coaxial Networking

Coaxial cable networking, often referred to as 10BASE5 or 10BASE2 Ethernet, was developed in the 1970s and 1980s. It used a thick or thin coaxial cable as a shared medium. This technology was a trailblazer, setting the stage for the networking revolution that would follow.

Speed and Reliability

Coaxial cables offered a data transfer rate of 2.94 Mbps, which was lightning fast for its time. However, its reliability was a double-edged sword. On one hand, the controlled impedance and self-shielding properties of coaxial cables made them a reliable medium for data transmission. On the other hand, the network’s reliability was its Achilles’ heel. If any of the wires broke or if the terminator was missing, the whole network would go down.

The Rise and Fall of Coaxial Networking

Coaxial cable networking became the standard because it was cost-effective and technologically advanced for its time. Copper was cheap, and the cost of electronics was relatively high. Running a coaxial cable to each machine and treating it like a true medium meant you only needed to install a single network interface in each computer.

However, as with all technologies, coaxial cable networking was eventually superseded. The advent of twisted pair Ethernet (10Base-T) and the decrease in the cost of networking electronics led to the decline of coaxial networking. The thinner and more flexible cable of twisted pair Ethernet was both cheaper and easier to use.

The Legacy of Coaxial Networking

Despite being replaced by newer technologies, the impact of coaxial cable networking is undeniable. It laid the groundwork for the networking technologies we use today and paved the way for the Ethernet we know and love. So, here’s to the coaxial cable - the trailblazer of networking!
