Very High Bit Rate Digital Subscriber Line (VDSL2) technology for triple play services

Abstract—In an Customer demand for triple-play services is on the rise, and cable operators have responded by adding services such as Internet access, VoIP, Video on Demand (VoD), and High Definition TV (HDTV) to their standard television service. Unfortunately for carriers and service providers looking to compete with cable and even satellite operators, triple-play services require a great deal more bandwidth than what is currently available over last-mile copper loops. To compete effectively for customer business and to create a future-proof network, carriers and service providers have a critical need for a fiber-fast broadband capability of 50 Mbps to 100 Mbps. While extending fiber to every home seems a logical solution, it is not feasible economically or competitively. Very-High-Bit-Rate Digital Subscriber Line 2 (VDSL2), a standard by the ITU-T. The proposed VDSL2 standard increases the spectrum allocation to 30 MHz for higher performance. VDSL2 enables fiber-fast broadband at speeds of up to 100 Mbps symmetrical—fast enough to deliver broadband applications such as the triple play of voice, data, and video.
