Fiber Optics: Get Familiar With the Fundamentals

0 Comments

Fiber optics technology is the advance signaling sensation used for communication and framing the object for illumination. Getting into depth of its basic helps you not only to know it better but also to use it better.

Starting with the question that you ask firstly when listening to the name-Fiber optics:

What is fiber optics?

Fiber optics is a technology that uses light to transmit data or electrical signal through optical fiber.

So what is Optical fiber?

Technically we define optical fiber as a transparent transmitting medium which guide the electrical signal in the form of light from source to destination.

Now to understand in simple terms, it’s a flexible light pipe made up of glassy material like silica or plastic that passes light between two ends of fiber.

When and where it was invented?

The story of fiber optics is started from the demonstration of light guiding principle by Daniel Colladon and Jacques Babinet at Paris in 1840’s. After this the introduction to phenomenon of total internal reflection by John Tyndall in 1870’s had set the stage for this technology. Then the fiber optics is followed by several experiments and advancement until Robert Maurer of Corning glass made it commercially available in 1970’s. Since then, use of this technology increases dramatically and its ease of installation and lower production cost make it popular now days.

How optical fiber is made and communicates through light?

Optical fiber is made up of glass or plastic material. Glass is usually a form of silica or crystalline material like sapphire. The construction of optical fiber is consisting of several layers. These are:

· Central core that carries the light signal.

· Cladding, that helps to keep light in the core.

· Outer coating to protect the cladding layer.

· Strengthening layer to bound the lower layer strongly. fiber optic engineering

· Lastly, an outer jacket to protect the fiber from environmental conditions.

Fiber optics communicate through light and its lightning application uses illuminator to perform this. The illuminator is a bright light source that focuses the light into the fiber. The light may be passing inside the fiber to create spotlight or end-glow effect or it may be emitted along the length of the fiber to create a neon or side glow effect over the surface of the fiber. These characteristics make them suitable for pool lightening and other display application.
