LONDON -- At this year's Broadband World Forum, Huawei released the industry's largest-capacity SuperVector solution through copper lines. This innovative solution enables a single device to support a maximum of 384 subscriber lines.
Under this solution, existing VDSL2/vectoring devices in fiber to the curb (FTTC) scenarios will be accelerated to 2-3 times the rate of original sites through board replacement. This solution also supports a downstream rate of up to 300 Mbit/s within a 300-m distance.
Currently, many operators owned a large number of FTTC sites and deployed the mainstream VDSL2/vectoring solution to provide 50–100 Mbit/s bandwidth for users. For most operators, efficiently and economically delivering over 100 Mbit/s rate in the FTTC sites is their top priority. Huawei's SuperVector solution can increase the bandwidth of VDSL2/vectoring devices by 2-3 times the rate of original sites, and thereby improving operators' competitiveness and granting a greater return on investment (ROI).
The new solution is developed based on the commercially used MA5603T device. Huawei has deployed its large-capacity vectoring algorithm chipsets and 64-channel high-density SuperVector service boards throughout this solution. Because of the solution's architecture, Huawei can provide over 100 Mbit/s bandwidth for 384 subscriber lines simultaneously. To meet the requirements of ultra-broadband services (such as 4K videos), the SuperVector solution extends the spectral bandwidth from 17 MHz to 35 MHz, uses the vectoring to reduce crosstalk, breaks VDSL2/vectoring rate limit, and delivers a downstream rate of up to 300 Mbit/s at a 300-m distance. In addition, it is compatible with existing ADSL2+/VDSL2/vectoring terminals, which enables smooth network upgrades without user perception.
The idea of SuperVector was first conceived in 2012 by Huawei. In 2014, Huawei, along with its European partners, launched the industry's first SuperVector prototype. Presently, many countries such as Italy and Germany have already commercially deployed Huawei's SuperVector solution while Asia-Pacific, Latin America, Middle East, and North Africa regions are conducting tests (including FOA tests) over the solution.
