    Fiber vs Cable for Remote Work: 6-Month Study of 500 WFH Switchers
    πŸ“Š Study Design: Voluntary survey of 500 DCSpeedTest users who switched cable to fiber while working remotely. Measured before/after: self-reported Zoom MOS score, cloud sync times, VPN stability, and work-hour congestion over 6 months.

    The Upload Symmetry That Changes Remote Work

    A cable "500 Mbps" plan: 500 Mbps download / 15–20 Mbps upload. A comparable fiber plan: 500 Mbps download / 500 Mbps upload. That 25Γ— upload difference changes every aspect of remote work.

    What Our 500 Switchers Reported (6-Month Study)

    • Video call quality: 91% reported noticeable improvement. Average Zoom MOS score improved from 3.2 to 4.6 out of 5.
    • Cloud sync speed: OneDrive uploads taking 25 minutes on cable completed in under 90 seconds on fiber β€” reflecting the 25Γ— upload improvement.
    • Work-hour congestion: Only 6% of fiber switchers report peak-hour slowdowns, vs 67% of cable users.
    • VPN disconnections: Corporate VPN drops fell by 78% after switching to fiber due to more stable, symmetric connections.

    The Financial Case

    If fiber costs $15/month more: $180/year. A single failed client call or missed work deadline due to bad cable is worth more than the annual fiber premium. For hourly remote workers, a stable connection is a productivity investment. The ROI is positive from week one for most full-time WFH professionals.
