Fibre optics is a new term and confuses many people and businesses. You may be looking for the best fibre cable installers around you and have no idea where to start. In our blog, we’ll talk about what fibre optics is and how it works so that you gain a general understanding of it.
Fibre optics sends information – coded in a light beam – through a plastic or glass pipe. It was developed in the 1950s for doctors to see through the human body before operating on it. Engineers found a way in the 1960s to use fibre optics technology, so it transmitted phone calls at light speed.
Optical technology
The fibre optic cable consists of this plastic or glass strands called optical fibres. Each strand is more delicate than human hair and carries around 25,000 telephone calls. So, an entire cable can transmit millions of calls.
The fibre optic cables carry information between two different places using optical technology. If you sent information from your computer to your friend across the street via fibre optics, you’d connect your computer to a laser. This would convert electrical information from the computer into light pulses, then fire a laser through the fibre cable.
After travelling through the cable, the light beams emerge on the other side. Your friend would need to have a photoelectric cell to convert the light pulses into electric information that their computer would understand.
How does fibre optics work?
Light travels through a fibre optic cable, bouncing repeatedly along the edges. Each tiny photon bounces through the pipe, making you think a beam of light travelling through a glass pipe can leak through the edges. However, if the light hits the glass at less than a 42-degree angle, it reflects again. This phenomenon is known as the total internal reflection.
Types of fibre optic cables
Optical fibres transmit light signals in modes (a path that a light beam travels through the fibre). One mode is going through the middle of the fibre. The other one is bouncing through the fibre at an angle.
Fibre cable installers use two different types of fibre optic cables:
Single-mode: Has an incredibly thin core of about a millionth of a metre. The signals travel straight to the middle and don’t bounce off the edges. Examples include the internet, telephone signals, and cable TV. These cables can send signals of up to 100km.
Multi-mode: Each optical fibre in this multi-mode cable is 10 times bigger than one in a single-mode cable. The light beams travel via different paths (yellow, blue, orange, or cyan lines). They send information through short distances, such as through linking computer networks. Looking for fibre cable installers?
