• The core part entails the glass fibers. It is the pathway of light signals.
• The cladding part is made of a different type of optical glass. It reflects light pulses back inside the core.
• It allows the single mode signals to travel long distances without losing their strength or quality.
• As protection, there’s a plastic coating around the glass cladding.
• To protect the cable from moisture and damage, there is a final layer of polyethylene.

1. Single-Mode Fiber
2. Multi-Mode Fiber

Opting for a new internet connection? Then you must be looking to choose the service which provides high-speed data. As it's a primary need of any internet user. When choosing the internet connection, we strive to get into every small detail. It is a sure thing that, you're familiar with cables, wireless devices, DSL. But, fiber optic systems may still be a mystery. Fiber optic cables are modern technology cables that can carry telephone calls and emails around the orb in seconds. For new adopters, the questions may arise that how fiber optic systems work? Would they be beneficial for your business? This article explains both of these questions and the working science behind these cables.

The Making

These cables are based on advanced technology standards. They are made of thousands of pure glass strands. Each of these strands is thinner than a human hair. These glass strands are bundled into an optical fiber cable with different types of parts described as below:

The core part entails the glass fibers. It is the pathway of light signals.

The cladding part is made of a different type of optical glass. It reflects light pulses back inside the core.

It allows the single mode signals to travel long distances without losing their strength or quality.

As protection, there's a plastic coating around the glass cladding.

To protect the cable from moisture and damage, there is a final layer of polyethylene.

The Working

There are two types of fiber cables available:

1. Single-Mode Fiber
2. Multi-Mode Fiber

Both of them are dependent on a light source to convert electrical information into pulses. Single-mode fiber uses the laser to create the light pulses that travel long distances. They are majorly used by government and educational organizations to extend fiber-optic networks across large campuses. Single mode cables carry signals for distances over sixty miles.

Multi-mode fiber optic cables work differently. They use LEDs as a light source. It has a core part with an average diameter of fifty microns. That's why there is a larger number of light signals passing through a multi-mode core than in single-mode. Multi-mode fiber optics are a perfect choice for shorter distances. For example, you can use it within a building. Multi-mode fiber is majorly used than the single-mode fiber cables.

The Advantages:

The fiber optic cables are based on a technology that ensures fast working and security. That's the reason market is already adopting them over the copper cables. Here are some of its benefits:

Speed: To provide faster uploads and downloads they move at 31% of the speed of light. That's almost the three times of more speed of copper cables. Copper cables move at 1% of the speed of light.

Reliable: The major benefit of Fiber optic cables is safety. It prevents currents from the core part. This makes the fiber optic networks more versatile. These cables do not entail a fire hazard, as electricity cannot pass through the glass. On the other hand, copper is prone to electricity and can pose a fire hazard if not carefully maintained.

Secure: Light doesn't discharge electromagnetic signals. It makes fiber cable impossible to tap. In any case, if security is violated, the light will leak out from the layers of glass and polyethylene. And that will make the system fail.

Low Cost: If you are planning to adopt fiber optics cables, it may seem like an investment initially. Although, it costs less in terms of maintenance. It doesn't demand much networking and hardware options compared to others.

Final Thoughts

Over the past few years, fiber optic networks have transformed the industry workflow. With their evolvement, they have replaced the copper cables majorly for long distance calls. When it comes to choosing internet services, there are multiple players in the market. At the same time, the industry is moving towards the direction that offers high-speed data with reliable solutions. That's where the fiber optics plays a major role. These cables are reliable, safe, and provide high accessibility to services. According to industry experts, fiber optics has taken the majority of internet connections with 99% of international communications. It is worth upgrade to fiber optics systems for sufficient speed and standard internet usage.

Inclusion And Adoption Of Fiber Cables

The phenomenon of transferring data up to long distances is not new to us. Thanks to satellite communications, data networks, broadcasters and cable operators, we can exchange the information we want whenever we want. This transmission of data is possible due to Fiber optic cables. Also, with the enhancement of technology, and inclination towards better performances, the utility of fiber optics is increasing with each passing day.

Today, we will know more about Fiber Optic Cables, how they evolved and a little bit about their working. First, let’s start with the introduction of Fiber Optic Cables.

So, what Are Fiber Optics?

Fiber Optic cables, also known as optical fibers are tiny strands (same size as human hair) of glass arranged in optical cable bundles. They’re an ultimate choice when one wants to transmit light signals to long distances. Every bundle of these cables comes with a jacket or an outer covering. Now look at a single optic fiber and you will observe that it has a core with a thin glass which helps the light to travel through it. Its outer optical layer surrounds the core and reflects light back to the cladding. It also has a coating which protects the fiber from damage and moisture.

There are two major types of fibers. One, single mode, and two, multimode. When it comes to transmitting data up to long distances, the electricians usually make use of single mode fibers. And for shorter distances, they make use of multi-mode fibers.

Now, let’s get into the history of Fiber Optic Cables.

History of Fiber Optics

You would be surprised to know that Fiber Optic Cables go back to the Roman era! Optical Telegraph is the first equipment that made use of these cables and enabled the operators to transmit the message from one tower to another through an array of lights on towers. The French Chappe brothers invented them in the year 1790.

1800s: The Phenomenon of Light Travel

In the year 1840, physicists Jacques Babinet and Daniel Collodon reported that they can direct light through the jets of water fountain. Thereafter, in the year 1854, John Tyndall, a British physicist proved that light signals can bend as they can travel through water jets.

Now, let’s talk about the Alexander Graham Bell era in the year 1880. He created a patent for an optical telephone which helped to enhance the optical technology further. In the same year, William Wheeler created a system of light pipes which produced light for the houses through an electric lamp in the basement.

Dr. Roth and Professor Reuss of Vienna made bent glass rods to illuminate body cavities in the year 1888. On the other hand, in the year 1895, Henry Saint Rene crafted bent glass rods that enabled the transmission of light images through TV. And last but not the least, in the year 1898, David Smith, an American scientist applied a patent for a dental illuminator.

1900s: The Further Progress of Fiber Optics

In the year 1930, Heinrich Lamm transmitted the image of a light bulb filament through a bundle of Optical Fibers. He was the first person to do so. Thereafter, Holger Moller Hansen applied for a patent in which he proposed plastic and cladding glass fibers having a low index material.

Holger Moller Hansen applied for a Danish patent in 1951 on fiber-optic imaging in which he proposed cladding glass or plastic fibers with a transparent low-index material, but as it was quite similar to Baird and Hansell patent given in 1926, the authorities didn’t accept it.

And now to the 70s. The year 1973 witnessed a chemical vapor deposition process which heated chemical oxygen to create an ultra-transparent glass which one can mass produce into a low loss optical fiber. Bell Laboratories was the body that introduced this phenomenon. In 1975, the Dorset police installed the non-experimental fiber optic link with the first live telephone traffic. During the mid-1980s, Sprint came into existence – which was a 100% fiber optic network.

In the year 1996, they laid the first optic fiber cable across the Pacific Ocean known as TP-5. It was made out of optical amplifiers. Fiber Optic Link Around the Globe – abbreviated as Flag was the longest single cable network and it laid the groundwork for the upcoming and advanced internet applications.

Several industries including data storage, telecommunication, industrial, networking and broadcast industries make use of fiber optic patch cables to the fullest. We hope you enjoyed reading about the history and evolution of the most significant type of cables. Watch out this space for more!
