Through this camp we learned more about Optic Fibre, and also about how it relates with light. Optic Fibre is also called Optical Fibre. We all made new friends in our groups, and became more independent. We learnt that an Optic-Fibre is thinner than a strand of hair. Using breadboards we made a transmitter and a receiver. Optic-Fibre only transmits lights. LED/laser converts electrical signals into light signals, then the Optic-Fibre transmits the light signal to the other end. The receiver converts light signals back to electrical signals. Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths than other forms of communications. Fibers are used instead of metal wires because signals travel along them with less loss. Light is kept in the core of the optical fiber by total internal reflection. Optic Fibre has many advantages. For example, Optic fibre can transmits signals longer and faster, less signal is lost and the capacity of the signals is larger than the tranditional copper wires, so Optic Fibre is very useful and helpful in many ways.
