Driven by the rising demand for higher bandwidth and faster speed connections for a variety of industrial and residential purposes, fiber optic transmission is becoming more and more common in modern society. It has become the predominant choice for Ethernet backbone infrastructure, high-speed internet services, and general data networking. Here we take a close look at the main reasons why.
According to a report by Fior Markets, the global fiber optics market is expected to grow to USD 7.89 billion by 2025 at a CAGR of 11.7% during the forecast period of 2018-2025. These statistics show fiber optic transmission is experiencing its prime time and will change telecommunications greatly.
Fiber Optic Transmission Technology
Unlike copper wire-based transmission, in which the transmission entirely depends on electrical signals passing through the cable, fiber optic transmission involves signals in the form of light. Usually, a fiber optic communication system consists of three main components: optical transmitter, fiber optic cable and an optical receiver. The optical transmitter converts the electrical signal to the optical signal; the fiber optic cable carries the optical signal from the optical transmitter to the optical receiver, and the optical receiver reconverts the optical signal to electrical signal.
The use and demand for speed and bandwidth have led to astonishing advancements in optical cable technology. Basically, there are six types of fiber cable in the market: OS2 fiber, OM1 fiber, OM2 fiber, OM3 fiber, OM4 fiber, and OM5 fiber cable. Because optical fibers are flexible and can be bundled into cables, they are employed as a communication and networking medium.
Main Benefits of Fiber Transmission
Optical fibers have largely replaced copper wire communications in core networks in the developed world, because of its advantages over electrical transmission. Here are the main advantages of fiber optic transmission.
Extremely High Bandwidth
When it comes to bandwidth, no currently available technology is better than fiber – especially single mode fiber. Fiber optic cables provide more bandwidth to carry more data than copper cables of the same diameter. The bandwidth-distance product (BDP) of transmission media is used to compare capabilities in this respect, and media with higher BDP will have longer transmission distance when sending the same bandwidth of data. The higher the BDP, the faster uncompressed video can be delivered and over greater distances, while displaying at exactly the same quality as the native signal. For example, the standard BDP for multimode fiber is 500 MHz/km, which means that 500-meter multimode fiber cable can transmit 1 GHz.
Longer Distance, Faster Speed
In fiber optic transmission, optical cables are capable of providing low power loss, which enables signals can be transmitted to a longer distance than copper cables. Basically, the light in fiber optic cables travels at roughly two-thirds the speed of light, while electrons in copper cables barely reach one percent of that speed. This immense speed advantage has an extreme effect on potential distances. Fiber optic cables have the ability to extend large bandwidth content across exceptionally long distances in a small diameter, whereas copper cables are mostly limited to a 100-meter standard distance.
Unlike copper-based transmission methods, fiber optic cables contain no metallic components. As a result, they are immune to electro-magnetic interference (EMI) and radio frequency interference (RFI). Furthermore, fiber optic cables aren’t impacted by temperature changes, bad weather or moisture. For example, if it comes into contact with rainwater, communication goes on as usual. If lightning strikes a fiber cable, the surge of electricity will not be propagated.
Low Security Risk
Because electricity isn’t involved with transferring data (data is transferred via light instead), it is impossible to remotely detect any data signal that is being transmitted, and attempts at physical access would be detectable by surveillance, which ensures the absolute security of information. Because of its security, fiber is the preferred transmission medium for businesses like the government and banks. Fiber optic cables are also completely safe in spark-prone areas like chemical factories and oil refineries.
Due to its effectiveness and high transmission capacity, fiber optic transmission is rapidly being employed in place of metal cables for data transfer. We have seen the fiber optic cables have replaced traditional copper twisted-pair cable or coaxial cable. There is no question that fiber optic transmission will open up additional prospects and be constantly investigated and improved to meet future demands as a result of the use and demand for large bandwidth and quick speeds.
