Fibre Optics in Plain English
The term ‘optics’ comes from a concentrated beam of light - a laser - which can concurrently transmit around a billion bits of voice, data and video information per second.
The ‘fibre’ is a bundle of fine, hair-thin flexible strands of glass.
Fibre Optic Cables transmit information by converting messages into light pulses that travel through the cables over long distances. Being smaller and lighter, these cables have the edge over conventional cables in ensuring a quicker and smoother flow of information.
Groundbreaking Work
Fibre optic cables have come a long way from the early ones made of flawed glass that could carry telephone and television signals through light pulses for about 65 feet before all the light dissipated. By 1970, an ultra-pure optical fibre that resembled a fishing line more than 2640 feet long came into being.
Soon fibre optics facilitated the production of broadband communications, biomedical informatics and countless other digital applications. A survey conducted in 2009 estimated that the number of fibre optics cables used worldwide would comprise a fibre more than 600 million miles long if laid out in a straight line.
The Role of Fiber Optics in Today’s World
Fibre optic cables can carry information ten times further than older styles of transmission before they need amplification. They are less susceptible to electromagnetic interference and carry way more data than older cables of the same size.
Help Spread The Message
Computers were once connected over long distances by telephone lines or Ethernet cables but have been replaced by affordable, reliable, secure and higher-capacity fibre cables.
The broadcasting industry transitioned from analogue to digital operations from electromagnetic waves to coaxial cables to optical fibres.
In Aid of Humanity
For more than 50 years, fibre optics have become an essential component in medical scanning and diagnosis devices that help doctors to look inside human bodies without cutting them open. Examples include gastroscopes and arthroscopes.
Help Wage the War
Cheap, lightweight, high-capacity, thin, robust and secure fibre optic cables offer a seamless way to link military bases with missile launch sites and radar tracking stations. They do not emit electromagnetic radiation, which is easily discovered and are immune to electromagnetic interference.
Potential Pros & Cons of Freelancing vs Full-Time Employment
Freelancing Fiber Optics Engineers have more flexible work schedules and locations. They have full ownership of the business and can select their projects and clients. However, they experience inconsistent work and cash flow, which means more responsibility, effort and risk.
On the other hand, a full-time Fiber Optics Engineer has company-sponsored health benefits, insurance, and retirement plans. They have job security with a fixed, reliable source of income and guidance from their bosses. Yet, they may experience boredom due to a lack of flexibility, ownership, and variety.
When deciding between freelancing or being a full-time employee, consider the pros and cons to see what works best for you.
