In 2009 Kao was awarded the Nobel Prize in Physics for his function. Plastic fibers, usually product of polymethylmethacrylate, polystyrene, or polycarbonate, are cheaper to produce and a lot more versatile than glass fibers, but their better attenuation of sunshine restricts their use to Considerably shorter links within structures or cars.
The optical fibers Employed in fiber optics are sometimes manufactured from plastic but most frequently are made of glass. An average glass optical fiber has a diameter of a hundred twenty five micrometers (μm) or 0.
Switches: Repeaters are to networks what transformers are to electrical power grids—They may be electronic products that obtain network alerts and clean up or reinforce them. Hubs are repeaters with various ports in them.
Campus location network (CAN): Campus space networks are a group of interconnected LANs. They're used by more substantial entities for instance universities and governments.
