G.fast: Clear a new path to ultra-broadband

G.fast lets network operators bring the speed of fiber to copper lines. With proven FTTx solutions and deployment expertise from Nokia, you can use G.fast to roll out FTTH faster and extend ultra-broadband services to every subscriber.


G.fast breaks down barriers to fiber deployment

Many operators want to use FTTH to deliver ultra-broadband to more people.

But some locations are hard to reach with fiber. The effort required to trench cable, dig up yards, and rewire households varies widely, adding complexity and cost.

New G.fast technology breaks down barriers to fiber deployment and clears the path to ultra-broadband.

The right G.fast solutions will help you:

  • Deliver fiber-like speeds over the last meters of existing copper infrastructure
  • Reduce CAPEX by deferring the cost of extending fiber to every building and home
  • Extend ultra-broadband to locations where fiber deployment is difficult
  • Eliminate the need to enter and rewire homes and buildings

Accelerate FTTH rollouts

Use G.fast to add flexibility to FTTH deployments and deliver high bit rates more cost effectively.

We make deploying G.fast as easy as choosing the right optical network terminal (ONT). Our G.fast-enabled FTTfd ONTs reduce your costs and effort by supporting reverse power and subscriber self-installation. They let you carry the speed of fiber to your customer's front door and avoid the cost of rewiring the home.

Our G.fast CPE channels the speed of G.fast throughout the home over dual-band Wi-Fi® connections, and powering the ONT is a breeze with integrated reverse power feed functionality.

Bring ultra-broadband to any user

Conquer your deployment challenges by combining FTTH and FTTx.

Our complete line of ISAM access products lets you reach any user with any access technology.

And our micro-nodes allow you to deploy these technologies anywhere that makes economic sense.

We'll help you clear roadblocks relating to subscriber density, multi-dwelling unit (MDU) access, and fiber installation so you can extend ultra-broadband services to every home.

Secure success with an experienced FTTx partner

Get to G.fast faster by working with a proven FTTx technology leader and deployment partner.

More than 20 operators rely on our award-winning VDSL2 vectoring solution, and we've shipped more than 8 million VDSL2 lines. Now, we're applying our vectoring expertise to G.fast to reduce crosstalk. And in 2014, we set new speed records with our Bell Labs XG-FAST technology prototype.

Our innovations and experience can help you make G.fast a reality in your network.


G.fast: Deliver high bit rates on short copper loops

Beyond VDSL2: G.fast will deliver fiber speeds over short copper loops

G.fast technology makes gigabit-level aggregate bit rates possible by adding spectrum to copper lines. Your current VDLS2 lines use spectrum up to 17 MHz. G.fast widens this spectrum to 106 MHz. Anticipated amendments will use frequencies up to 212 MHz and take bit rates to 1 Gbps and beyond.

The high frequencies of G.fast can't be sustained over long distances. The best approach is to use a mix of technologies. G.fast is ideal for applications that bring fiber closer to the home and use very short copper loops to cover the last few meters. VDSL2 vectoring remains the best technology for longer copper lines.

Like VDSL2, G.fast lines are susceptible to performance-degrading crosstalk when combined in the same cable. Our Bell Labs researchers have proven that crosstalk has a much greater impact on high-frequency G.fast lines. They have also identified factors that make vectoring more complex with G.fast. Their work is behind our multi-port G.fast solutions, which cancel out crosstalk and make G.fast even faster.


Where to deploy G.fast

Because it works on short copper loops, G.fast must be deployed in conjunction with fiber rollouts. But you can leverage your existing assets. FTTH operators can use the passive optical network (PON) to backhaul G.fast-enabled ONTs. And traditional FTTx operators can use G.fast to increase bit rates without having to extend fiber all the way to the home.

You can deploy G.fast at distribution points located 250 meters or less from subscribers. The use of short copper lines lowers subscriber density.

This means you can roll out ultra-broadband services using low-cost micro-nodes that serve 1-16 subscribers. G.fast can deliver value in many different deployment scenarios, including:

  • Front door – Eliminate the cost of installing fiber in the home
  • Distribution point – Bring more bandwidth to more people by deploying micro-nodes close to residences
  • MDU – Cut deployment costs by connecting individual living units with existing copper infrastructure
