Gfast Physical-Layer Testing Solutions

Gfast Physical-Layer Testing Solutions promises to bring a wealth of new opportunities to Service Providers as well as manufacturers of DPUs, CPE Modems and Chipsets. This exciting new technology allows for a more efficient use of existing copper infrastructure by utilizing the spectrum above 30 MHz and by cancelling the crosstalk between pairs within a cable. This increases data rates far beyond current levels, making bandwidth-intensive applications such as IPTV and Triple Play available in many areas where it was not possible before.

User-friendly configuration software allows the user to select and build impairment models common to DSL network implementations using ADSL2+, VDSL2, VDSL2 vectoring and G.fast. A generous assortment of custom crosstalk as well as impulse noises (e.g., REIN, SHINE and PEIN) can be created. It can also generate a wide variety of interferences above 30 MHz that may impact G.fast deployments. These include background Gaussian noise, high frequency impulse noise (PEIN, SHINE), FM radio, Broadcast TV, Spark Plug Ignition noise, PLC noise, Reverse Power Feed noise and more. In addition, user-defined files in several formats (such as MATLAB. CSV and Excel) may be imported. Optional noise modules automatically setup standards-based testing for TR-114, TR-105, TR-115, TR-100 and more.
