OpenVault: Fiber Use Increasingly Outpaces Cable, Gap Continues to Widen

WASHINGTON, April 9, 2026 – In the battle between fiber and cable, fiber is showing robust growth.

Consumers using fiber internet are uploading far more data than people on cable internet (DOCSIS), and that gap is only growing, according to preliminary first quarter data shared by OpenVault.

Last week, OpenVault’s CEO and Co-founderMark Trudeau announced that fiber broadband crossed a major threshold in uploads at 106.7 GB per month, which is the first time fiber users averaged more than 100 GB uploaded. Compared to DOCSIS networks which averaged 56.9 GB, fiber users uploaded almost twice as much data.
