What is the difference between fiber cable and normal cable?

Difference Between Fiber Cable and Normal Cable

Fiber optic cable and normal cable, often referred to as copper cable, are two primary mediums for the transmission of data and telecommunication signals. The core differences between these two types of cables lie in their material composition, data transmission methods, speed, and overall performance.

Material Composition

  • Fiber Optic Cable: Made from glass or plastic fibers that transmit data in the form of light.
  • Normal Cable: Consists of copper wires that transmit data through electrical signals.

Data Transmission and Speed

  • Fiber Optic Cable: Offers significantly higher speeds and bandwidth compared to copper cables. It can transmit data over longer distances without loss of signal quality.
  • Normal Cable: Limited by the resistance of copper, leading to potential signal degradation over long distances and lower bandwidth.

Durability and Reliability

  • Fiber Optic Cable: More resistant to electromagnetic interference, weather conditions, and physical damage. It does not carry electric current, reducing the risk of fire.
  • Normal Cable: Susceptible to interference from electromagnetic sources and can be affected by environmental factors. Carries an electric current, which poses a higher risk of fire.


  • Fiber Optic Cable: Initially more expensive to install due to the materials and technology involved. However, its durability and lower maintenance costs can make it more cost-effective in the long run.
  • Normal Cable: Cheaper to install but may incur higher maintenance costs and need more frequent replacements.


  • Fiber Optic Cable: Ideal for high-speed internet services, data centers, and long-distance telecommunications.
  • Normal Cable: Commonly used for residential internet connections, local network setups, and telephone services.

In summary, while fiber optic cables offer superior speed, reliability, and bandwidth, normal cables are more cost-effective for short-distance applications. The choice between the two depends on the specific needs of the application, including speed requirements, budget, and environmental considerations.
