The Role of Fiber Optic Cables in Computer Networking

Do you think fiber optics are essential to meet internet necessities? What is it? And Why are they important in computer networking? In this blog, we will show you the role of fiber optics in computer networking and discuss why fiber optic services are considered as the future of connectivity.

What is Fiber Optic Cable?

Fiber optical cables or fiber optics is a technology associated with the transmission of information as light pulses along with a glass or plastic strand or fiber. Fiber optic cable is a network cable containing strands of glass fibers inside an insulated casing.

Fiber optical cables are mainly used for long-distance and high-performance data networking and telecommunications. The main purpose of the fiber-optic network is to reach longer distances and provide higher performance in comparison to wired cables.

Fiber optic cables are able to support large bandwidths and provide connectivity for much of the world’s internet and television. While wired cables on the other hand cannot possess large bandwidth.

How Fiber Optic Cables Work?

Fiber optics cables consist of one or more strands of glass. The center of each strand is called the core that provides the pathway for light to travel. The core is surrounded by a sheet of glass called cladding that reflects light inward to avoid loss of signals and passes the light through bends in the cable.

Fiber optics cables having unique features help in preventing the loss of signals. One optical fiber cable has the strength to carry three million voice calls. Primarily there are two types of optic cables — single-mode and multi-mode.

Single-mode cable with extreme thin glass strands uses a laser to generate light while multi-mode cable uses the LED’s. Single-mode optical fiber networks make utilization of Wave Division Multiplexing techniques and increase the amount of data traffic that strand can carry. Using a single light pulse it can effectively transmit multiple communication streams.

Fiber Optic Cable Advantages:

Fiber Optical Cables over long-distance copper cabling offer several advantages to its users -

• Fiber Optic Cables support higher capacity. The amount of network bandwidth a fiber optic cable carries can be easily exceeded by copper cable with similar thickness.
• Light can travel for much longer distances over a fiber cable without losing its strength and that is why the need for signal boosters is lessened.
• Fiber optic cables are less susceptible to interference. A copper network cable requires shielding to guard it against electromagnetic interference. This shielding is not sufficient to prevent interference when many of the cables are strung together in proximity to one another. The use of fiber optic cable helps avoid most of these problems.

Fiber Optics in Computer Networking

With fiber optic communication you can easily set a high-security system for transmitting confidential government data, personal, monetary, and medical data. Fiber optic cable giving reliability keeps your information secure. It provides a secure mode to transport signals from one place to another.

Below is a list of reasons why fiber optic cable networking is used with computer networking.

• Transmission with fiber optic cable is faster.
• Fiber optic communications are future-proof.
• Fiber optic cable transmission can easily cover long distances.
• They are impervious to electromagnetic interference.
• The use of fiber optic cables helps in saving space and enhances cable management.
• The use of fiber optic cables lowering data leakage helps in data privacy and protection.
• Fiber optics cable due to its non-metallic transmission medium avoids spark.
• Provides immunity to different kinds of interference, Electromagnetic Interference (EMI) or Radio Frequency Interference (RFI), Crosstalk due to electric or magnetic fields of a signal.

To Sum Up

Because fiber optical cables are not subjected to electromagnetic interference it can also be used for a variety of medical instruments. It can be used for various medical tests like MRI scans, X-RAY imaging, endoscopy, light therapy, and surgical microscopy.
