OKI demos 160G bps transmission

Oki demonstrated a 160G bps transmission across a distance of 635 kilometers in Japan.

Oki Electric Industry Co. said on Wednesday that in an experiment, the company pushed 160Gb of data in a second over fiber across a distance of 635 kilometers.

In more practical terms, the test demonstrated the potential to send four movies in a second from Tokyo to Osaka, Oki said.

The manufacturer worked with the National Institute of Information and Communications Technology and used the Japan Gigabit Network II, an optical network research environment available to manufacturers and institutions.

Oki installed optical amplifiers along the network and also used its 160G-bps transceiver as part of the test. The transceiver supports such high transmission speeds by using time division multiplexing and four modulators that create 40G-bps optical signals, the company said. The transceiver then multiplexes the four signals to create one 160G-bps optical signal.

The trial showed that the technology could be used for backbone lines connecting cities such as Tokyo and Osaka, which are 500 kilometers apart, Oki said.

The company plans to commercialize its 160G-bps transceiver and expects the technology to be available after 2010.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
