Cable + Fiber
Optimum Speed Test
Optimum serves the New York tri-state area and parts of the South/West with a mix of cable (HFC) and a growing fiber network. That split matters: Optimum Fiber plans are symmetric and can reach multi-gig speeds, while cable-served addresses get traditional asymmetric speeds — so what your test 'should' show depends on which network you're on.
What speeds should Optimum deliver?
On Optimum cable, expect downloads near your tier (100–1,000 Mbps) with uploads capped around 20–35 Mbps. On Optimum Fiber, plans are symmetric — 300/300 up to multi-gig — and wired tests should show matching upload and download.
Not sure which you have? A symmetric test result (upload ≈ download) means fiber. A big gap means cable, and upgrading to fiber (where available at your address) is often a free or cheap switch that transforms upload performance.
Slow Optimum speeds? Try this first
- 1Reboot the Optimum gateway monthly; long-uptime cable modems commonly drop bonded channels and lose speed.
- 2If you're on cable and fiber is available at your address, ask Optimum to migrate you — pricing is often identical for far better upload speed.
- 3Test wired via ethernet before calling support; Optimum's included gateway WiFi is a frequent bottleneck in larger homes.
- 4Evening-only slowdowns on cable indicate node congestion — log tests at consistent times to make your case to support.
