In the upcoming future, VDSL2, ADSL2 and ADSL2+ will represent the mainstream in broadband access. As a result of higher bandwidth and lower broadband access costs, a wider variety of value-added services ranging from broadband Internet access to bandwidth-consuming video applications will be offered. Many Telcos will offer such value-added services as competing technology against their competitors to provide the triple-play services, including voice, data and video.
VDSL and ADSL are complementary technologies used in different network topologies. ADSL2 and 2+ are used for longer loop applications and dispersed subscribers, while VDSL2, the fastest offering of DSL, is used for applications requiring higher bandwidth within shorter loops. Due to the limitation in distance, VDSL2 is best used for tenants in densely populated locations. The symmetrical bandwidth of VDSL2 also makes it an optimal choice for a variety of applications such as video-conferencing and large file transfers.
Because of recent heavy investment in PTM infrastructures, many service providers will migrate to use IP networks for VDSL2 in the coming years. ZyXEL maintains its leading position as a VDSL2 equipment provider and continues to provide cutting-edge IP-based, DMT VDSL2 technology that interoperates with all major CO equipment vendors.
To fulfill the market trend and needs, ZyXEL offers a complete range of VDSL2 products, ranging from the CPE, pizza-box and chassis-based solution to fit different applications for service providers and Telcos.
