Farmers will be connected to the Internet a powerful laser.

Staff, University of Melbourne, and NEC have developed a technology that would provide residents of rural areas of Australia's broadband internet access, writes Electronista. Researchers hope that the high power laser can reduce the cost of laying fiber in rural areas.
Currently, developers of technology are experimenting in the Australian state of Victoria, hoping to provide broadband access 99 per cent of its residents. In total there live more than five million people and a population density of about 23 people per square kilometer.
The basis for the experiment was the current gigabit passive optical network. Data transmitted over fiber to the passive splitter, which разводят signal to households. Typically, the signal fades, passing about thirty kilometers.
The researchers used Raman laser and the output signal increased almost tenfold. They were able to transfer data at speeds of 2.5 gigabita per second over a distance of about sixty kilometers.
The advantage of the new development is to reduce the number of splitters in the two-fold. Disadvantage - more stringent requirements for security channel and other equipment.
