Fujitsu white paper lays out path to 400G

May 15, 2013
While 400G announcements tend to get all the news and media attention, substantial R&D efforts are continuing on the 100G evolution path, contends Fujitsu.

A new white paper from Fujitsu notes that, with 100G units now widely available, the industry is turning its R&D focus to 400G optics. At the same time, however, ongoing investment and evolution of 100G technology will result in smaller size, reduced power consumption, and lower costs of 100G interfaces.

Industry standardization efforts at 100G are widely recognized as a tremendous success, points out Fujitsu. At 400G, the industry standards are largely still in the discussion stage, and will be maturing over the next 2–3 years into a formal standard. While many see the 400G standards efforts as late, they timeframe is consistent with carrier 400G deployment timeframes and reinforced by industry research from Ovum, as cited by the company.

The paper explains how, while 400G announcements tend to get all the news and media attention, substantial R&D efforts are continuing on the 100G evolution path to reduce size, power consumption and costs. For many carriers, these improvements to 100G technology will offer substantial, more immediate benefits for their networks, contends Fujitsu.
