Continue reading to find out how our daily applications successfully use fiber optics and how it is affecting internet networks and other communication channels.

What is Fiber Optics?

The term “fiber optics,” sometimes known as “optical fiber,” describes the technique used to transport data via light pulses traveling along a glass or plastic fiber. These glass fibers can range in quantity within a fiber optic cable from a few to several hundred.

A cladding is another glass layer that encases the glass fiber core. A buffer tube layer shields the cladding. Furthermore, the jacket layer serves as the last line of defense for each individual strand. The benefits of fiber optic cables over copper lines make them widely employed. A few of these advantages include increased bandwidth and transmit speeds. Fiber optics makes long-distance and high-performance data networking feasible. The internet, television, and telephones are all forms of telecommunication that use it frequently.

Transmission Technology of Fiber Optics

Light particles, or photons, that pulse across a fiber optic cable carry data when it is transmitted using fiber optics. Incoming light is bent at a specific angle because the glass fiber core and cladding each have a different refractive index. Following a mechanism known as total internal reflection, light signals passed through fiber optic cable bounce off the core and clad in a series of zigzag bounces. The denser glass layers prevent the light signals from moving at the speed of light; instead, they move around 30% more slowly. Fiber optic transmission occasionally needs repeaters at a distance to re-enforce, or amplify, the signal along the way.

Through electrical signal conversion, electrical signal processing, and optical signal retransmission, these repeaters recreate the optical signal. Signals up to 10 Gbps can now be carried via fiber optic connections. Typically, a fiber optic cable’s price rises in direct proportion to its bandwidth capacity.

Presence of Fiber Optics in Different Sectors

Fiber Optic Network – Role of Fiber Optics in Internet

Everyone today is using the internet in one or multiple ways, be it on their personal or professional front. Working people undoubtedly depend on cloud-based services like Dropbox or Google Drive to keep your business productive. The introduction of cloud computing services and technologies has significantly altered how businesses conduct their operations. The ability to obtain information instantly is increasingly expected in the environment we live in.

Businesses need to evaluate their network architecture in order to continue providing the increasing demands of quick access. Losses in workplace efficiency and productivity may be brought on by slow internet speeds, high latency, and “capped” connections. And in some of those locations, fiber optic networks can be helpful.

Fiber optic networks’ greater connection speeds is a boon for both individuals as well as businesses. Fiber optic networks can offer strong advantages to assist your organization stay better connected thanks to their potential tremendous benefits, such as improved cloud connectivity, voice over IP (VoIP) capabilities, and overall better capacity.

Additionally, it is now simpler to incorporate a fiber optic network to obtain faster connectivity and higher productivity. This is because fiber optic networks are more widely available to both homes and companies.

Fiber Optic Transmission Technology

The three primary parts of a fiber optic communication system are typically an optical transmitter, fiber optic cable, and an optical receiver. The optical transmitter changes the electrical signal into an optical signal. Fiber optics then transmits this optical signal to the optical receiver.

Further, the fiber optics then changes the optical signal back into an electrical signal. Semiconductors such as LEDs (light-emitting diodes) and laser diodes are the most widely utilized optical transmitters. An optical receiver’s crucial component is the photodetector. The photodetector effect converts light into electricity. The evolution of optical cables is astounding because of their use and demand for speed and bandwidth.

For various optical applications, there are currently OS2 fiber, OM1 fiber, OM2 fiber, OM3 fiber, OM4 fiber, and OM5 fiber cable available on the market. It is possible to create bundles of fiber optic cables due to their flexibility and ability. Consequently, optical fibers find usage as a communication and networking medium.

Because light propagates through the fiber with less attenuation than electrical copper lines, it is particularly advantageous for long-distance communications. The graphic below demonstrates how all fiber optic transmission methods send information from a transmitter to a companion receiver using modulated light.

Pros and Cons of Fiber Optics

Higher Bandwidth

The bandwidth of fiber optic cables is substantially higher than that of metal cables. Fiber optic cables have a considerable advantage over conventional transmission media since they can send information in less time per unit of data. Furthermore, it’s becoming more crucial to have high bandwidth available as more enterprises need to transmit data.

Your current network may greatly benefit from an upgrade to fiber optic connectivity if it is experiencing low bandwidth, having trouble meeting some of your current business data transfer needs, experiencing issues with multicast video breaking down, having problems with your CCTV images pixelating or shearing, or having trouble accessing cloud applications.

Better Speed

Being able to post films, files, and conduct phone calls while simultaneously downloading stuff has become the new normal in our fast-paced culture. Therefore, slow Internet connections might cost firms many weeks of output. In order to make your organization as productive as possible, it is essential that your internet connectivity is quick, effective, and dependable.

fiber optic networks, with options ranging from 5 Mbps to 100 Gbps, are much quicker than even the highest-speed copper Internet connections. Your employees can gain from equal upload and download speeds with a quick data connection with a fiber optic network.

Extended Transmission Ranges

Fiber optics have negligible power loss. Therefore, it is possible to transmit data over longer distances at higher bandwidths. Contrary to copper cables’ maximum operating distance of 100 meters, fiber optic cables can travel tens of kilometers.

Increased Adaptability

Unreliable connectivity can result in significant expenditures for companies. Unplanned downtime of any length can completely halt business productivity. Reliable communication and connectivity are essential to any organization.

Fiber optic cables are more lightweight and thinner than copper cables. Compared to copper, fiber is more resistant to breakage and damage and can handle higher draw pressure.

Fiber is pliable, bendable, and resistant to the majority of corrosive substances that frequently damage copper wires. Further, fiber optic data connections are completely immune to electromagnetic interference, lightning, and radio transmissions because they do not carry electrical currents. The main purpose of copper wires is to transmit electricity. Thus, copper networks are susceptible to induced power, lightning, and intentional signal-scrambling. Additionally, fiber optics have strong resistance against bad weather, which can obstruct or impede data transmission through copper cabling.

Mitigates Latency

Fiber optics networks resolve many latency problems that cable internet users encounter, especially when downloading or uploading videos or viewing high-definition material. Lowering latency could have a positive impact on your organization by allowing you to transfer more apps to the cloud, download and upload large files without interruption, and boost employee cooperation.

Robust Security

Since fiber cables don’t emit signals. Thus, it is extremely challenging to attach taps to one to intercept data flow. fiber optics safeguards the data comprehensively. It is exceedingly challenging to tap without your knowledge and does not emit any signals. Fiber optics requires the installation of all hardware and electronics in one area, as opposed to copper systems, which requires installation of the equipment in distribution sites all throughout a facility. Thus, fiber optics offers higher physical security.

Since each fiber strand in a fiber cable contains the signal that travels through it, the signal must be accessed from the cable’s end by cutting into it. In most instances, this would bring the network to a halt, and everyone would become immediately aware of the problem.


While fiber optic transmission offers a lot of ease, it also has drawbacks that one should not overlook.

Extremely Fragile

The basic construction material of fiber optics is generally glass. Therefore, these fiber optics are more fragile in comparison to electrical wires. Additionally, because glass is susceptible to chemical reactions, such as hydrogen gas (which is an issue for underwater cables), it is important to take extra precautions while deploying glass underground.

Tough Installation Process

Fiber optic cable splicing is difficult. And they will crack if you bend them too far. Additionally, fiber cable is sometimes cut during its installation. All of these make installation challenging.

Requires Additional Equipments

Light will attenuate and spread as transmission distance increases. Henceforth, this necessitates the addition of more optical components like EDFA.

Need of Special Equipments

Fiber optics sometimes require some sort of special equipment to ensure its transmission’s quality. For instance, expensive, specialized optical test equipment like optical probes and power meters are needed at the majority of fiber endpoints to adequately offer testing of optical fiber. The name of this equipment is OTDR (optical time-domain reflectometry).

Expensive than Other Contemporaries

Installing fiber optic cabling is still more expensive than installing copper cables, despite the fact that fiber optic installation costs are decreasing by as much as 60% annually. since installing copper lines does not require special care like installing fiber cables. Although FTTx (fiber to the home, premises, etc.) and PONs (passive optical networks) enable subscriber and end user broadband access, optical fiber is still making its way into the local loop.


Fiber optics are now extensively present in many sectors of the economy. The need to invest in future-proof technology, like fiber optics, to enable innovation and growth has never been greater.
