Fiber Optics Time Delay

Allowing optimal conditions, light can travel the fastest, which is 186 x 10-3 in a vacuumed space. That, however, is the most favorable suited only as a benchmarking data. Practical light applications have to consider a number of involvedness of other elements, impeding its travel speed to a considerable degree.

Fiber optics is just like light and it is ruled by same principles. The purpose of this text is to show you about fiber optics time delay: how mediums can affect the light’s speed and ability to pass through and emphasizing on its finiteness.

Considering the Fiber Medium

Refraction, as a property of light, states that light travels and propagates at a finite speed. When light passes through a translucent matter, the optical fiber in our discussion, the light’s speed is reduced, a phenomenon known as Refraction. This is the most significant consideration for fiber optics media, those purest and impurities free glass substance are very desirable. For illustration, ever wonder how earth can be more radiant than in space where there isn’t any obstructions to reduce the sun’s (or the star’s) illumination? The answer would be the light’s passage of an impure medium, which is our atmosphere, and thus scattering around light particles.

So, from the above statement, anyone can deduce that using the formula for velocity makes a valid product.

v = s ÷ t

Where:
Velocity equals the speed (of light) divided against the time it takes for the light to reach a point

However, precision is most hindered when using this formula due to contrasting differences of the digits, those markedly huge numbers for distance and minute numbers for the speed of light. The product, while useful in some instances, can be very inaccurate for those precision oriented projects.

That makes the fiber optics time delay hardly measurable using practical methods; considerable equipment is to be needed for an accurate fiber optics time delay product. However, you can also derive the fiber optics time delay product using the Index of Refraction Formula, where normally, the refractive index value of a fiber optic thread is already made available by the manufacturer.

n = c ÷ v

Where n is the Index of Refraction, c is the constant 186,282.397 miles per second or 186 x 10-3 miles per second –the speed of the light achievable under optimal circumstances, and v is the speed of light traveling within a medium, fiber optics time delay. So therefore:

v = c ÷ n
