“Progress in Development Wired Access Broadband Networks” Technologies, Markets and Applications

Wired broadband access technologies are playing an important role in today networks. Until recently, technical and economic problems with such access did not allow effective use of a broadband pipe from a core to a subscriber side, minimizing a value of broadband communications.

The problems have been known for a long time, but absence of a cost-effective technology in the distribution plant prevented making any practical improvements. The specifics of access, such as the necessity to create highly distributed infrastructure and the price to support access service always contradicted each other. The situation changed with appearance Passive Optical Networks and vectoring DSL.

The goal of this report is to address current and near-term advances in wired broadband access networks that are transforming them into broadband pipes with characteristics similar to characteristics of the core networks. Particular, the report concentrates on the analysis technologies and markets for the following access architectures:

  • Passive Optical Networks (PONs) – standardized or planning to be standardized by the IEEE and ITU-FSAN. Evolving PONs will allow transmission up to 100 Gb/s (shared).
  • New generations DSL – in the development and standardization by the ITU and the industry, including vectoring and The technology may support short reaches connectivity on the existing copper structures with speeds 1 Gb/s and up (non-shared).
The report shows that the copper infrastructure continues playing an important role for connecting last hundreds meters from/to a subscriber equipment (with the rest of network). Advanced gigabit speed access technologies, such as DSL (, VDSL2-vec), are key in creating a homogenous and cost efficient core-access infrastructure.

PONs provide cost-efficient connectivity of the core with subscriber’s equipment, supporting required by users characteristics, such as speed of transmission and other.

The report also stresses an important trend in the broadband wired access: utilization of multi-functional platforms that allow flexibility and cost efficiency to serve a diversified group of users required different technologies.

The standardization processes are analyzed in details. Marketing statistics have been developed. The report also presents detailed surveys of companies that are working in the related industries and their products portfolios. Attachments contain the survey of recently approved patents related to the subject of this report.

The report is written for a wide audience of technical, managerial and sales staff involved in the development wired broadband access networks, addressing advances in their technologies as well as applications and markets.
