How have we revolutionized long distance communication?
Coaxial cable communication lines use electricity to transfer large amounts of data throughout the globe. Coaxial cable wires are practical in electrical wiring since they have high conductivity, high tensile strength and are extremely ductile. This makes it great for electrical applications but when transferring large amounts of data throughout the globe, these advantages become obsolete. They pose several problems on top transferring data slowly and inefficiently. Some of these problems are that coaxial cables must be placed a fair distance away from the electrical wires since electricity might act as interference. Due to their conductivity, coaxial cables need to be placed indoors since they attract lightning (Weaver, 2014). Again, due to their conductivity property, coaxial cable wires can pose a threat of injury from fire and electrocution. They are not efficient for large distances between continents because of the loss in data.
In addition to this, with more people having access to phones and internet, there was a need for faster network communication.
The solution to the problem lied in fiber optic cables. Fiber optic cables provide a safer and a faster method of transferring data in large quantities. This is done by using light as a source of data transfer instead of electricity. This is done by sending LED's or lasers through the fiber optic cable so that the light can be received at the other end.
