Fill the gaps in your ultra-broadband network

Vplus is a new FTTX technology that accelerates ultra-broadband deployments. Faster than VDSL2 and serving greater distances and more customers than G.fast, Vplus fills the gap and enables aggregate speeds of up 300 Mbps.

Vplus complements VDSL2 and G.fast

Operators the world over are turbo-charging their FTTX networks to provide ultra-broadband services. VDSL2 vectoring is ideal for high densities of subscribers over a wide range of local loops up to 1000 meters in length. G.fast caters to low densities on short loops of less than 300 meters.

But in between, there’s an opportunity for fast speeds and high densities.

Vplus fills the gap between VDSL2 vectoring and G.fast. At loop lengths between 250 and 550 meters, Vplus can give you better performance than both VDSL2 vectoring and G.fast.

Offer premium services

Use Vplus to deliver double the speeds of VDSL2:

• 200 Mbps+ up to 500 meters

• 300 Mbps+ up to 250 meters

Connect more customers
per node

Connect up to 200 subscribers on a single Vplus node. That’s 12 times more customers than G.fast.

Generate better ROI

• Earn increased revenues from premium ultra-broadband services

• Lower cost per subscriber with higher density nodes

• Enjoy a smooth upgrade path from VDSL2 to Vplus

How Vplus works

Vplus uses a new profile – classified by the ITU as VDSL2 profile 35b – which extends frequencies to 35 MHz (compared to 17 MHz for VDSL2). This extended frequency range makes it possible to achieve aggregate speeds of up to 300 Mbps, compared to 150 Mbps for VDSL2. However, Vplus signals can still travel several hundreds of meters before attenuating.

Vplus is also compatible with VDSL2 17a vectoring. That means the two technologies can sit side by side in the same local loop, with vectoring used to improve the performance of all lines. This ensures a smooth introduction of Vplus in your VDSL2 network.

FTTX technologies compared

In FTTX deployments, broadband speeds increase the closer the “X” gets to a customer. The downside is cost: Each FTTX node serves fewer customers, which decreases the density – and that increases the cost per subscriber.

In other words, every FTTX technology has its “sweet spot”: an area in which it performs best based on distance, speed, and cost.

Vplus fills the gap between VDSL2 vectoring and G.fast

Choosing the right technology

The Vplus sweet spot

You can deploy Vplus in a number of ways.

• Boost broadband speeds on medium length FTTX lines
  Use Vplus in an existing VDSL2 vectoring cabinet deployment to offer premium broadband services on medium to short lines (less than 550 meters).

• Boost broadband speeds on long FTTX lines
  Deploy small Vplus cabinets or micro-nodes closer to your customers’ homes where local loops are greater than 550 meters. This shortens the final loop length, resulting in faster broadband.

• Provide ultra-broadband services on new FTTX deployments
  Plan and design your new FTTX deployments for the Vplus sweet spot (250–550 meters).

The benefits of Vplus

Vplus gives you significant advantages over VDSL2 vectoring or G.fast.

• Up to double the speed of VDSL2 on loops shorter than 550 meters

• Higher speeds than G.fast beyond 250 meters and higher density (100–200 subscribers)

• A seamless upgrade path from VDSL2 vectoring (17a)

Vplus is the most cost effective technology for medium loop lengths:

• The 35 MHz frequency range keeps down equipment costs and footprint when compared to G.fast (106 MHz)

• This frequency range also means 75% less processing power for vectoring compared to G.fast

• Less complex equipment increases subscriber density, which is critical at medium loop lengths
