1.1 Uses of optical fibre in communication

Using optical fibres, very high data rates (gigabits per second and higher) can be transmitted over long distances (tens of kilometres) without amplifiers or regenerators.

This class examines the role of science in the US environmental policy-making process. It investigates the methods scientists use to learn about the natural world, the way scientific knowledge accumulates, the treatment of science by advocates and the media, and the role of science in legislative, administrative and judicial decision making. It also considers how other political systems use science in an effort to put the US approach in comparative perspective.
