Superfast Broadband

Superfast broadband transformed UK homes by bringing dramatically higher speeds over existing telephone lines. If you’re wondering what “superfast” really means and how it compares to other options, Rocket Fibre has you covered. In simple terms, superfast broadband delivers download speeds of at least 30 Mbps—fast enough for HD streaming, online gaming, and multiple users. Here’s everything you need to know about superfast service, how it works with fibre to the cabinet (FTTC), and why Rocket Fibre’s full-fibre alternatives give you even better performance.

Defining “Superfast” in the UK

Ofcom, the UK’s communications regulator, defines superfast broadband as any service offering at least 30 Mbps download speeds. Before its rollout:

• Standard ADSL capped at around 8–10 Mbps, leaving households frustrated by buffering and slow page loads.

• Superfast (FTTC) uses fibre-optic cable to the street cabinet, then copper lines to your home, boosting speeds to 30–80 Mbps (sometimes up to 100 Mbps).

These speeds cover the needs of most families: multiple HD video streams, cloud backups, online gaming, and smooth Wi-Fi on many devices.

How Fibre to the Cabinet Works

Fibre to the cabinet (FTTC) was the first major upgrade from all-copper ADSL. Here’s the basic setup:

1. Core Network to Street Cabinet

High-capacity fibre-optic cables run from the exchange to street cabinets distributed throughout your neighbourhood.

2. Cabinet to Your Home

Existing copper telephone lines carry the data the final few hundred metres. Copper still limits the maximum speed, but FTTC typically delivers between 30 and 80 Mbps.

3. Router at Home

You plug in an FTTC-compatible router, often supplied by your provider, to create a Wi-Fi network and wired ports.

Because the bulk of the distance uses fibre, FTTC greatly improves broadband speeds over pure copper.

Is Superfast Enough for My Home?

Superfast broadband covers most common uses:

• HD Streaming: Two or three simultaneous HD streams run smoothly at 5–10 Mbps each.

• Online Gaming: Low latency plus 30+ Mbps download keeps game downloads fast and play responsive.

• Video Calls & Remote Work: 5–10 Mbps upload and 30+ Mbps download support Zoom, Teams, and large file transfers.

• Smart Homes: Multiple devices—phones, smart TVs, security cameras—can all stay connected.

However, as households adopt 4K streaming, 8K media, smart home hubs, and home-office demands, superfast may start to feel limiting—especially at peak times or in larger homes.

Rocket Fibre’s Full-Fibre Alternative

Rocket Fibre goes beyond superfast with full-fibre or FTTP (fibre-to-the-premises), which means fibre runs directly into your home. Benefits include:

• Gigabit Speeds: 300 Mbps, 600 Mbps, or 1 Gbps symmetric speeds (same upload and download).

• Lower Latency: Essential for competitive gaming, cloud apps, and video calling.

• Consistent Performance: No copper means no speed loss due to line degradation or peak congestion.

• Future-Proof: Fibre’s huge capacity supports 2 Gbps or 10 Gbps upgrades without new wiring.

For many, moving to full-fibre is the next logical step once superfast shows its limits.

How to Check Your Superfast Coverage

1. Postcode Checker: Visit Rocket Fibre’s website and enter your postcode. You’ll see if FTTC superfast is available or if you qualify for FTTP.

2. Current Speeds: Run a broadband speed test. If you regularly see 30–80 Mbps downloads, that’s likely FTTC.

3. Router Status: Log into your existing router to check its connection type—VDSL indicates FTTC, whereas “PON” or “Unlimited Optical” suggests full-fibre.

Choosing the Right Option

• On a Budget: If FTTC superfast is the only option and suits your usage, it remains an affordable choice.

• Busy Households & Remote Work: Consider Rocket Fibre’s full-fibre for higher, more reliable speeds and symmetric uploads.

• Growing Needs: If you plan to add multiple 4K streams, cloud backups, or smart-home devices, FTTP will serve you longer without upgrade hassles.

Rocket Fibre’s Superfast & FTTP Plans

Rocket Fibre offers both superfast and full-fibre packages tailored to your location:

• Superfast Starter (FTTC): Around 50 Mbps downstream, 10 Mbps upstream—great as a budget or backup option.

• Full-Fibre Home (FTTP): 300 Mbps symmetric for families streaming and working together.

• Power User (FTTP): 600 Mbps symmetric for heavy data users and home offices.

• Business Edge (FTTP): 1 Gbps symmetric for small businesses, co-working spaces, and gamers who demand the fastest speeds.
