New Report Shows Data Consumption on Fiber Dominates Cable

WASHINGTON, May 14, 2026 – In a recent report, OpenVault found that fiber internet is rapidly outpacing cable internet in terms of data consumption at peak times. 

The median usage for fiber subscribers is more than triple that of Data Over Cable Service Interface Specification (DOCSIS) subscribers, OpenVault found.

OpenVault, an analytics company led by CEO Mark Trudeau, also found that more than a third of fiber customers are consuming at least 1 TB of data per month, an increase over users on DOCSIS. Downstream fiber usage also outpaced DOCSIS subscribers by 26.1%. This includes during peak hours from 6-10 pm, as downstream traffic was as much as 3.6 times higher on fiber networks compared to DOCSIS networks.
