Running Ethernet on old wiring

Twisted pair Ethernet (10 and 100 Mbit/s) uses two pairs of wires. 10BASE-T Ethernet was designed to be be used on CAT3 quality wiring. 100BASE-TX was designed to be used with CAT5 wiring or better. Since the early 2000s most new structured cable installations are built with Category 5e or Category 6 cable. There are

Ethernet in sensing

In the modern world sensors are used for recording everything from exhaust gas temperatures to the electrical activity in a human heart. Direct wiring methods are commonly used for simple on-off device control, where a circuit is either open or closed. Likewise, digital sensors are usually wired directly to monitoring panels in the world of

Data center backbone design

Cells vs. packets: What’s best in the cloud computing data center? article from few years back tells that resource constrained data centers cannot waste anything on their way to efficiency. One important piece on this is right communications technology between different parts of data center. In the late 1990s and early 2000s, proprietary switch fabrics

Ethernet trends

Without Ethernet our networked world would cease to exist. It’s the ubiquitous standard for local area networks. The internet is probably Ethernet’s greatest triumph. Practically every server that delivers content to the internet is networked via Ethernet. Without Ethernet development the internet will choke. Society is moving to a new level of interconnectedness that’s built
