If you’ve ever stared at an Ethernet cable wondering whether to use T568A or T568B, or blanked on the pin order during an exam, you’re not alone. I kept mixing up the color sequences and device pairing rules, so I built a quiz app to drill them into muscle memory.
I created Cabling Trainer while studying for a networking certification. Reading diagrams wasn’t enough — I needed repetition, speed drills, and a way to test myself on real-world device scenarios without wiring up physical cables every time. The app started as a simple flashcard tool, but I added game modes to make the grinding less tedious.
What it does
The app covers the fundamentals you’ll see in any IT certification exam or entry-level networking job:
- Direct vs crossover cable identification: Quiz yourself on when to use straight-through or crossover wiring based on device pairs (PC-to-switch, router-to-router, etc.)
- T568A and T568B color order drills: Four game modes that force you to recall pin sequences under time pressure — Catch the Wires (order falling colors 1-8), Fix the Order (spot two swapped pins), Time Attack (60-second speed rounds), and Simon Says (memory sequence game)
- Real equipment scenarios: Practice with PCs, hubs, switches, routers, servers, home routers, and POS terminals — all the device combinations that show up on exams
- Coupler logic: If one side of a coupler uses a certain cable type, what do you need on the other side? The app walks you through these scenarios
- Progress tracking: Daily accuracy trends, your top 5 most-missed device pairs, learning streaks, and total study time
The games are designed to build speed and accuracy. Time Attack mode is especially useful if you’re prepping for timed exams — you learn to recall the sequences instantly instead of mentally counting through the colors. Simon Says helps with short-term memory, which matters when you’re physically crimping cables and can’t keep looking at a reference sheet.
Who it’s for
I built this primarily for networking students and IT certification candidates (CompTIA Network+, Cisco CCNA, etc.), but it’s useful for anyone who touches Ethernet cables and wants the wiring standards at their fingertips. If you’re in a help desk role, doing field installs, or just tired of Googling “T568B pinout” every time you need to make a cable, this will save you time.
The app is free, supports dark mode, and has English and Korean interfaces. Ads are present but placed to avoid interrupting your study flow — no mid-quiz popups. Version 1.0.1 just shipped with rewritten English learning content for a global audience, so the terminology should feel natural whether you learned networking in the US, Europe, or anywhere else.
If you’re studying for a cert or just want to stop second-guessing yourself when wiring patch cables, give it a try. It’s on the Play Store now.
