Comprehensive comparison between VDSL access network technology and ADSL Technology

VDSL access network technology is still quite common. So I have studied the comprehensive comparison between VDSL access network technology and ADSL technology. Here I will share with you, hoping to be useful to you. XDSL Broadband Access Technology Based on copper cables has been widely used in the market. As the mainstream technology of ADSL and VDSL access networks, it will gradually become integrated with the development of technology.

In the existing network, IP addresses almost occupy the entire metropolitan area network. For example, if ATM-based ADSL technology is used, the conversion and efficiency between ATM and IP addresses must be solved, at the same time, ADSL technology also has insurmountable shortcomings such as low rate asymmetry, low bandwidth, and low outbound rate.

VDSL applications based on the Ethernet kernel technology have been developed to meet the development requirements of network and service-based IP and Ethernet and solve problems existing in ADSL technology. VDSL access network technology not only solves the problem of converting between ATM and IP addresses, but also overcomes the problem of low transmission bandwidth and low outbound rate. However, VDSL access network technology also has the defect of short coverage distance than ADSL.

In fact, no access technology can solve all the problems, and each access technology has its applicability. Therefore, how can we reasonably and flexibly apply these two access technologies based on factors such as network status, line resources, and user distribution to complement the advantages of ADSL and VDSL, it has become a common concern of telecom operators and equipment manufacturers.

In the current situation, using the ADSL and VDSL hybrid plug-in technology to achieve the integration of the two access methods on the device is undoubtedly the best way to combine the current ADSL and VDSL access network technology. This construction mode not only has the advantages of integrated network management of ADSL and VDSL, unified operation and management, unified sharing of uplink ports, and simplified network structure, in addition, the ADSL and VDSL access networks can be flexibly selected based on objective factors such as user distribution, bandwidth requirements, transmission distance, and line quality to achieve cross coverage for different users.

Currently, the ADSL and VDSL access networks in the industry are very mature. The Hammer10000 IP Access Switch of Beijing Port and Bay network Corporation, which is commercially available in the market, adopts the pure Ethernet kernel technology, the same backplane and Exchange Control Network are fully shared between the ADSL and VDSL business boards, enabling the VDSL access network technology and the same-frame hybrid insertion function of ADSL. In the future, ADSL and VDSL technologies will be further integrated. In the near future, the same twisted pair may be used without any changes to network devices and users, you can achieve flexible access to VDSL or ADSL.
