This prestigious recognition celebrates how collaborative engineering excellence creates extraordinary societal impact. USB’s familiar cables and connectors stand as symbols of innovation that truly connected the world. > Read the article in IEEE Spectrum · Share this article: May 21, 2026 · From the beginnings of connecting printers and mice, USB now powers smartphone charging, high-speed data transfer, and video output through the versatile USB Type-C connector that has become universally recognizable. Nearly three decades later, USB continues its evolution. The milestone plaque was unveiled at the same Intel campus where pioneering companies conducted USB interoperability testing during the technology’s early days.

This USB cable was used in 2003 to connect a keyboard to Apple’s G4 computer. In particular, the engineers wanted something that was inexpensive, user-friendly, able to power peripherals, and offered a lot of bandwidth.To keep manufacturing costs down, the engineers designed USB to work with a slender, four-conductor cable that could be as long as 5 meters. One end of the cable had an A connector, which plugged into the computer; the B connector on the other end plugged into the external device. At the time, computers didn’t typically provide power for such external devices. Most peripherals had to be plugged into an outlet while connected to a PC. But USB allowed a computer to supply sufficient power for some peripherals. At 12 megabits per second, USB 1.0 was “faster than anything else that normally would come at the back of the PC,” Pappas told Fast Company. The team encountered a problem, though: 12 Mb/s was too fast for computer mouses, joysticks, keyboards, and other accessories with unshielded cables.

Launched in 2019 and requires USB Type-C. Unlike earlier versions, USB4 can tunnel multiple data types (USB, DisplayPort video, and optionally PCIe), enabling flexible performance sharing across devices like docks, storage, and displays. USB4 uses clearer speed branding (USB 40Gbps, USB 80Gbps) alongside spec labels like USB4 Gen 3x2 and USB4 Gen 4x2. Passive USB4 40Gbps cables are commonly limited to 0.8m/2.6ft; Power Delivery can still negotiate up to 240W on capable ports. The USB-IF’s newer, speed-first marketing names (USB [data rate]) simplify compatibility shopping for USB hosts and devices. Knowing the translation between old and new labels helps you pick the right cables, ports, and docks without guesswork. 2017: Renamed to the “Gen” scheme (e.g., USB 3.2 Gen 1x1 = 5Gbps; USB 3.2 Gen 2x1 = 10Gbps; USB 3.2 Gen 2x2 = 20Gbps), which you’ll still see on product pages. Today’s marketing simplifies this to USB 5Gbps / 10Gbps / 20Gbps, and uses the USB Standard-A or Type-C for 5Gbps and 10Gbps, and Type-C exclusively for 20Gbps. ... Typical passive cable guidance: up to 2m/6.6ft for 5Gbps; up to 1m/3.3ft for 10/20Gbps. The USB Implementers Forum (USB-IF), a non-profit organization that manages USB technology standards, has revised specs and marketing names multiple times, including retroactive renames, so the same port or speed may appear under different labels depending on the era.

The IEEE 802.3af, 802.3at, and 802.3bt Power over Ethernet (PoE) standards specify more elaborate power negotiation schemes than powered USB. They operate at 48 V DC and can supply more power (up to 12.95 W for 802.3af, 25.5 W for 802.3at, a.k.a. PoE+, 71 W for 802.3bt, a.k.a. 4PPoE) over a cable up to 100 meters compared to USB 2.0, which provides 2.5 W with a maximum cable length of 5 meters. ↑ "The history of USB: What you need to know".

Prefab is the biggest time-saver for 2026 and beyond. Here are the signals pointing toward the next wave of cabling evolution: Beyond PoE — upcoming IEEE standards may push even higher power delivery over structured cabling. Between 2025 and 2026, the cabling industry is shifting toward speed, density, and reliability. What sticks are the trends that make networks easier to install, easier to scale, and easier to maintain. As we move from 2025 into 2026, the big question becomes: Which cabling trends truly matter, and which ones will fade out? Fiber adoption surged in 2024–2025, and 2026 will cement it as a standard for: ... If you’re not offering fiber as your default backbone option, you’re behind. PoE used to power phones and a few IP cameras. Now it powers: ... More wattage + more endpoints = higher heat loads in cable bundles.
