Huawei has introduced a new technology prototype, dubbed SuperVector, which it claims substantially boosts copper access speed when compared to VDSL2 vectoring. In lab tests conducted with European operators, Huawei said the SuperVector prototype achieved 400 Mbps over 300 meters copper, which is three times the speed of VDSL2 vectoring, and 100 Mbps over 800 meters copper, which is suitable for 4KTV services. Huawei explained that SuperVector technology works by extending the frequency band from 17 MHZ to 35 MHZ, using the same DMT modulation and tone width as existing VDSL2 vectoring to ensure that the system is backward compatible. The company also introduced an innovative coding technology, optimised signal spectrum and improved transmission efficiency with a view to significantly upgrading the copper access speed.
According to Huawei, SuperVector can help operators improve access speeds based on existing DSLAM, FTTC, FTTB sites. The technology is particularly useful for enhancing long-distance copper broadband coverage in rural areas and is fully compatible with VDSL2 vectoring terminals.
