“Glass-less” Fiber Increases Data Transmission Speeds


We are all familiar with copper and glass fiber optic cable, but how intriguing is the thought of fiber cable without the glass? Made with an air core, researchers from the University of Southampton in England say they have created fiber cables that can move data at 99.7% of the speed of light! In an information technology article on arstechnica.com, it is explained that silica glass, as a medium, slows data transmission approximately 30%. So, the research team took the glass out of the glass fiber resulting in a “hollow-core photonic-bandgap fibre” which is made mostly of air yet still allows light to follow the path of the cable when it bends.

The article goes on to say “The methods used by the researchers result in data loss of 3.5 dB/km, an impressively low number considering its incredibly low latency. However, that data loss is still too high for long-range communications. For now, these cables won’t be used to wire up Internet Service Provider networks or for transatlantic cables.” Read the full article now

What do you think, is glass-less fiber the wave of the future?

    Kinda adds a new definition to “air-blown fibre” doesn’t it now?
