Fiber vs Cable vs DSL: Which Internet Type is Best for You?
The Infrastructure Wars
Not all internet is delivered the same way. The physical medium entering your house dictates your latency floor and reliability.
Fiber (FTTH)
The Gold Standard. Data travels as pulses of light on glass strands. Immune to electromagnetic interference. Symmetric speeds (Download = Upload).
Ping Floor: ~1-3ms.
Coaxial Cable (DOCSIS)
The Incumbent. Uses existing TV cabling. Susceptible to interference and congestion if many neighbors are online. Typically Asymmetric (High Download, Low Upload).
Ping Floor: ~10-15ms.
DSL (Digital Subscriber Line)
The Dinosaur. Uses old copper telephone lines. Distance varies wildly. If you are far from the node, speed drops drastically.
Ping Floor: ~20-40ms.
Conclusion
If you have the choice, Fiber is always the correct answer for gaming, even if the "speed" (Mbps) is lower than a cheaper Cable plan. 100 Mbps Fiber beats 1000 Mbps Cable for latency stability every time.
