Today operators all over the world are working on their FTTX networks improving to provide an ultra-wideband access services. A special place in this process is given to VDSL2 vectoring and G.fast technologies. Thus, VDSL2 vectoring technology is ideal for the use in areas with a high density of subscribers, located at 1000 m distance from the node. G.fast is intended to serve areas with low-density of subscribers at up to 300 m distance. But, until recently, no solution has been proposed to provide a subscriber with high-speed access at high-density subscriber placement in small distance from the station.

Vplus technology is designed to fill the void between the VDSL2 vectoring and G.fast. Vplus can provide better performance than VDSL2 vectoring and G.fast, at distances of up to 500 m (200 Mbit/s) and up to 250 m (300 Mbit/s). In this case, it is possible to connect up to 200 subscribers to a single node that is 12 times more than at G.fast usage.

How Vplus works

Vplus uses a new profile that is classified by ITU as VDSL2 35b profile, which operates at frequencies of up to 35 MHz (unlike VDSL2, which operates at frequencies of up to 17 MHz). Extended frequency range allows achieving aggregate data rate up to 300 Mbit/s that is twice bigger than the maximum rate for VDSL2.

Vplus is compatible with VDSL2 17a vectoring technology. It allows these technologies to operate effectively in the same cable. It also ensures smooth Vplus introduction into the existing VDSL2 network.

Benefits of Vplus technology

Vplus technology has significant advantages in comparison with VDSL2 vectoring and G.fast:

Vplus technology is the most cost-effective technology for medium length lines:
