Technologies and Markets: 40 Gb/s and 100 Gb/s Systems and Polarization Mode Dispersion

The report addresses the progress that the telecommunications industry is making in the development of ultra-high speed networks (40 Gb/s and 100 Gb/s). It updates and revises published Practel’s reports on this topic written in 2004-2010. The report details the standardization process for these technologies and is analyzing the major trends. It also provides the marketing analysis and the survey of the major industry players and their products. The early demand for 40 Gb/s capacity created already a significant market; 100 Gb/s networks are also introduced and the market expected to reach a sizable amount in 2012-2013. The report also concentrates on one of the major problems in ultra-high speed communications - Polarization Mode Dispersion (PMD); it analyzes its nature, sources and mitigation measures. It also addresses the industry needs to cope with PMD. In a summary, the report: Addresses the progress in the development of 40 Gb/s and 100 Gb/s technologies Reflects the recent advances in these technologies standardization Analyzes equipment and service market components Shows that one of the major trends is the development of techniques that allow using 10 Gb/s engineering rules for 40 Gb/s and 100 Gb/s spans Shows that the industry has adopted an integration of PMD compensators with various techniques for PMD mitigation (coherent receiver, advanced forms of modulation, efficient FEC and other). In such a way, 40 Gb/s and 100 Gb/s networks can achieve satisfactory results in the performance even when utilizing old fiber.

Methodology

Considerable research was done using the Internet. Information from various Web sites was studied and analyzed; evaluation of publicly available marketing and technical publications was conducted. Telephone conversations and interviews were held with industry analysts, technical experts and executives. The overriding objective throughout the work has been to provide valid and relevant information. This has led to a continual review and update of the information content.
