IB Physics: Activity: Optical fibres

Digital devices communicate with each other with a series of 1"s and 0"s. This can be achieved by converting the information into an electrical signal comprising of a high potential and a low potential.The signal is read at a constant rate so in the case above the signal would be 10100110This signal is transmitted along wires but as the wire passes from one device to another it will pass close to other electrical devices...
