Ethernet Unplugged: A Journey Through Networking’s Backbone – From 10 Mbps to 100 Gbps and Beyond.

Hey everyone, it’s Juan David here, your Tech Lead Support at Flytec! Today, we're taking a deep dive into one of the unsung heroes of the networking world: Ethernet. This little protocol has been with us through thick and thin, evolving from its humble beginnings in the early 1970s to the powerhouse that fuels our data-driven world today. From delivering speeds of just 10 megabits per second in its early days to today’s mind-blowing 100 gigabits and beyond, Ethernet has truly come a long way. So, let’s explore how Ethernet grew to become the backbone of everything we rely on in networking.

The Origin Story: Ethernet’s First Steps

Let's wind the clock back to the 1970s. Ethernet was born at the Xerox Palo Alto Research Center (PARC) by Robert Metcalfe and his team as a solution to connect computers in a local network. Back then, the idea of a "network" wasn’t as mainstream as it is now. The goal? To move data between computers at a speed that would actually be useful in real-time. And the result? The first Ethernet standard could transmit data at 10 megabits per second (Mbps) over coaxial cables – a big deal at the time.

Fun Fact: That 10 Mbps speed might sound slow today, but it paved the way for data sharing, which was groundbreaking in the ‘70s. Imagine a world with no real-time data sharing – crazy, right?

The Evolution of Ethernet Speeds: How We Got Faster and Faster

Alright, so Ethernet started at 10 Mbps. Back then, it was powered by 10BASE5, the original coaxial technology that laid the foundation for modern networking. That worked well for a while, but as technology grew and data demands surged, we needed faster speeds. That’s when Ethernet began its journey through various milestones, each one setting a new standard and raising the bar for what’s possible in network connectivity.

Fast Ethernet: 100 Mbps and the Age of 100Base-TX

Fast forward a couple of decades, and we arrive at Fast Ethernet, also known as 100Base-TX, hitting speeds of 100 Mbps. Using Category 5 (Cat5) UTP cables, 100Base-TX supported distances of up to 100 meters (328 feet) per segment. This was a game-changer, especially for businesses. Suddenly, transferring large files and handling more complex applications was no longer a bottleneck. Fast Ethernet was the first step in making Ethernet a reliable solution for both homes and businesses.

Gigabit Ethernet: 1 Gbps and the Rise of 1000Base-T

Then came Gigabit Ethernet, offering a whopping 1 gigabit per second (Gbps) – ten times faster than Fast Ethernet. Standards like 1000Base-T became the most popular for copper cabling, running over Cat5e or Cat6 cables with distances up to 100 meters. With Gigabit, Ethernet went mainstream in homes and offices everywhere. Suddenly, bandwidth-heavy activities like video conferencing, streaming, and file transfers were smooth, opening a new world for productivity and entertainment.

Why Gigabit Matters Today: Even now, Gigabit Ethernet is a popular choice in many networks because it offers the right balance between speed and cost like the Ubiquiti UDM or Mikrotik RB3011UiAS-RM. Most of our day-to-day activities don’t require anything faster, but it’s nice to know that higher speeds are available when we need them.

2.5G and 5G Ethernet: Bridging the Gap

As applications became more data-intensive, intermediate speeds like 2.5 Gbps (2.5G) and 5 Gbps (5G) emerged. Standards like 2.5GBase-T and 5GBase-T operate over Cat5e and Cat6 cables, making them cost-effective upgrades for existing infrastructure. These speeds are ideal for modern Wi-Fi 6 access points, high-performance workstations, and NAS devices.

10-Gigabit Ethernet: The Arrival of 10G for Data Centers and Beyond

Now, for those who need speed, 10-Gigabit Ethernet came onto the scene, providing 10 Gbps. Standards like 10GBase-T run over Cat6a or Cat7 cables, with distances of up to 100 meters. Data centers and enterprise environments jumped on board, using 10G to handle high-performance computing, virtualized environments, and tons of data moving at lightning speed.

In data centers, 10G became essential for things like server-to-server communication, cloud storage, and other heavy-duty tasks. Today, this speed is common in enterprise networks and even some high-end home setups. Products like the MikroTik CRS328-24P-4S+RM and Ubiquiti USW-Pro-48 are perfect examples, offering the robust performance and capacity needed to keep up with these demanding environments

Pro Tip: If you’re building a network for tasks that require massive data throughput (think rendering farms, complex simulations, or large-scale video editing), 10-Gigabit Ethernet could be your best friend.

25G and 40G Ethernet: Meeting New Demands
As data demands grew, Ethernet standards like 25GBase-SR and 40GBase-SR4 emerged. Using multimode fiber, 25G Ethernet provides high performance for single-lane connectivity, supporting distances of up to 100 meters. Meanwhile, 40G Ethernet leverages parallel lanes to aggregate speed, allowing it to achieve distances of up to 150 meters using four lanes of 10G.

100-Gigabit Ethernet and Beyond: The Backbone of Today’s Internet

As the demand for data continues to grow, Ethernet evolved yet again to 100-Gigabit Ethernet (100G). Standards like 100GBase-SR10 for multimode fiber and 100GBase-LR4 for single-mode fiber extend connectivity to 40 kilometers or more. This speed level is what keeps the backbone of the modern internet running.

With 100G, service providers and massive data centers can keep up with the explosive data needs of streaming, cloud storage, and Internet of Things (IoT) applications. Products like the MikroTik CRS504-4XQ-IN exemplify this technology, bringing robust 100G capabilities to handle high-performance requirements in critical infrastructure.

Looking Ahead: 200G and 400G Ethernet

Ethernet doesn’t stop at 100G. The development of 200G and 400G Ethernet standards is already reshaping how hyperscale data centers operate. These speeds use advanced multiplexing and new fiber technologies to handle unprecedented data loads, ensuring the infrastructure can scale for the next decades.

Wrapping Up: Ethernet’s Ongoing Legacy

Ethernet’s journey from 10 Mbps over coaxial cables to 100 Gbps and beyond is a testament to its adaptability and importance. It’s rare for a technology to stay relevant for over five decades, but Ethernet has managed to do just that. Whether you’re a networking pro or just tech-curious, Ethernet is something you interact with every day, whether you realize it or not.

If you’re building out a new network, planning an upgrade, or just trying to keep up with tech, remember that Ethernet is here to stay – and it’ll keep evolving to meet the needs of the digital age.
