How Each Technology Works
Fiber internet transmits data as pulses of light through fiber-optic cable. It is resistant to electromagnetic interference and often delivers consistent speeds regardless of distance.
Cable internet uses coaxial cable built for TV service. Fast downloads are common, but bandwidth is shared with nearby households.
The Upload Speed Gap Is the Real Differentiator
A cable plan advertised at 500 Mbps may provide 500 Mbps download but only 20–35 Mbps upload. Fiber typically delivers matching upload and download speeds.
When to Choose Fiber
- You work from home and rely on video conferencing
- Multiple people need simultaneous upload bandwidth
- You want consistent speeds during peak evening hours
- Fiber is available at a comparable price
When Cable Is the Right Call
- Fiber is not available at your address
- Cable is significantly cheaper in your area
- Your usage is download-heavy
- You are in a low-congestion area
