The Advantages and Disadvantages of Fiber Optic Transmission

Uploaded2021/8/17 1:46:55     Hits    Source

Due to the increasing demand for high bandwidth and high speed connections for various industrial and residential purposes, optical fiber transmission using optical fibers has become more and more common in modern society. Here are some detailed information on the advantages and disadvantages of fiber optic transmission.



The bandwidth of fiber optic cables is much higher than that of metal wires. Compared with copper cables, the amount of data that fiber optic cables can transmit is much larger.


Safety is the main concern of people today. Data or signals are transmitted by light in optical fiber transmission. Therefore, there is no way to detect the data being transmitted by "monitoring" the electromagnetic energy "leaking" through the cable, so fiber optic cables is one of the safest ways to transmit sensitive data.


In fiber optic transmission, fiber optic cables can provide low power loss, which allows signals to be transmitted over longer distances than copper cables.

Size & Weight

The diameter of the fiber optic cables is very small. Its small size can save more space in optical fiber transmission. Optical cables are made of glass or plastic so they are thinner than copper cables.



Usually fiber optic cables are made of glass, which makes them more fragile than copper cables. Because fiber optic cables are small, they can easily be accidentally cut during building renovation or rewiring. Optical fibers are also sensitive to bending, which makes laying optical fibers in corners a tricky task. In addition, fiber optic networks are also susceptible to radiation damage or chemical exposure, so you need to be more careful when laying fiber optic cables underwater.


Although the cost is lower in the long run, the price of installing fiber optic cabling is still relatively higher than that of copper cables. It usually requires special test equipment and installers with skilled knowledge to lay fiber optic networks. Optical fiber end points and connection nodes also require special equipment and settings. If the cable is damaged, it needs higher costs to fix it.

Attenuation & Dispersion

As the transmission distance gets farther and farther, the light will be attenuated and dispersed, which requires the addition of additional optical components, such as EDFA.

Installation Challenges

The splicing of fiber optic cables is not easy. If you bend them too much, they will break. They are easily cut or damaged during installation or construction.


Because of its efficiency and capacity, optical fiber transmission is being widely used and continues to replace coaxial and copper cables for data transmission. Fiber optic cables are used for different purposes in various industries such as communications, broadcasting, industry, military, and medical. With the use and demand for large bandwidth and fast speed, optical fiber transmission will undoubtedly bring more opportunities, and it will continue to be studied and expanded to meet future needs.
