How to Choose Fiber Optic Cable

When it comes to selecting the right fiber optic cable, there are several key considerations that you should keep in mind. By understanding these factors, you can ensure that you choose the most suitable cable for your specific application.

One of the first things to consider is the distance that the cable needs to cover. Different fiber optic cables have different transmission capabilities, with some designed for shorter distances and others capable of spanning much longer distances. The choice between singlemode and multimode fiber will depend on the network’s speed and distance requirements.

Network speed is another crucial factor to consider. Fiber optic cables are available in different types, each offering varying data transmission speeds. Multimode fiber cables are typically used for shorter distances and offer lower data transmission speeds, while singlemode fiber cables are better suited for longer distances and can support higher speeds.

The cable jacket is also an important consideration. The jacket protects the fiber optic cable and ensures its durability. It is crucial to choose a cable jacket that meets the local fire codes, especially if the cable will be running through risers or plenum spaces. Additionally, flexibility and strength under tensile load should be assessed to ensure that the cable can withstand the demands of its environment.

Moreover, it is essential to consider the connectors that will be used with the fiber optic cable. The connectors must match the ports on your network equipment to ensure a seamless and efficient connection. Pay attention to the specific type and number of fibers required by the equipment.

Lastly, considering the cost and future-proofing is crucial. While it’s important to select a cable that meets the current needs of your network, it’s also wise to anticipate future growth and technological advancements. Opting for a cable that offers room for scalability can save you the hassle and expense of replacing it in the near future.

By carefully evaluating factors such as distance, network speed, cable jacket, connectors, cost, and future-proofing, you can confidently choose the right fiber optic cable for your network requirements.

Choosing the right fiber optic cable involves careful consideration of various factors, including network speed, distance, cable jacket, and connectors. By selecting the most suitable cable for your specific application, you can ensure optimal performance and reliability.

Key Considerations for Choosing Fiber Optic Cable:

  • Distance: Determine the transmission distance required for your network.
  • Network Speed: Consider the data transmission speed needed for your network.
  • Cable Jacket: Choose a jacket that meets local fire codes and offers the necessary flexibility and strength.
  • Connectors: Ensure connectors match the ports on your network equipment.
  • Cost and Future-Proofing: Consider both the immediate cost and the potential for scalability in the future.

By taking these key considerations into account, you can make an informed decision and choose the fiber optic cable that is best suited for your networking needs.

Network Speed and Distance

The choice between multimode and singlemode fiber optic cables should be based on the network design and the required network speed and distance.

Multimode fiber is suitable for short distances (less than 300 meters) and can be cost-effective. It is commonly used in local area networks (LANs), data centers, and short-range applications.

Singlemode fiber is preferred for longer distances and higher data transmission speeds. It is typically used in wide area networks (WANs), long-haul applications, and telecommunications networks.

The range of multimode fiber depends on its OM rating, which indicates the quality and performance of the fiber. The OM rating is based on the bandwidth and modal dispersion characteristics of the fiber. Generally, higher OM ratings offer better performance and longer transmission distances.

On the other hand, singlemode fiber is capable of transmitting data over long distances up to 100km. It has a smaller core size and enables the transmission of higher wavelengths, allowing for higher signal quality and longer reach.

Cable Jacket

When it comes to selecting a fiber optic cable, one important factor to consider is the cable jacket. The cable jacket serves as the outer protective layer of the cable, providing insulation and safeguarding the internal components from external elements. It plays a crucial role in maintaining the cable’s performance and protecting it from damage.

All indoor fiber optic cables must meet local fire codes and regulations. The cable jacket should be rated accordingly if the cable is intended to be installed in riser or plenum spaces. These spaces often require cables with specific fire ratings to ensure safety. The fire rating indicates the cable’s ability to resist and prevent the spread of fire.

The flexibility of the cable jacket is another important aspect to consider. Optimum flexibility allows for easier installation and routing of the cable, especially in tight spaces or areas with complex cable runs. A flexible jacket ensures that the cable can be maneuvered around corners, bends, and obstacles without compromising its performance or integrity.

Tensile strength is another consideration when evaluating the cable jacket. The jacket should be designed to withstand the mechanical stresses and strains placed on the cable during installation and operation. It should have sufficient strength to resist pulling forces and protect the delicate fiber optics inside.

Color coding of the cable jacket is often used to differentiate between different types of optical fibers in a cable. For example, a yellow jacket is typically associated with single-mode fiber, while an orange jacket indicates multimode fiber. This color coding aids in identification during installation and maintenance tasks.

Jacket Properties:

  • Fire rating according to local regulations
  • Flexibility for easy installation
  • Tensile strength to withstand mechanical stresses
  • Color coding for fiber identification

Choosing the right cable jacket is essential to ensure the cable’s compliance with fire regulations, proper installation, and optimal performance. By considering factors such as fire rating, flexibility, tensile strength, and color coding, you can select a fiber optic cable with a suitable jacket that meets your specific requirements.

Jacket Property Description
Fire Rating Indicates the cable’s ability to resist and prevent the spread of fire
Flexibility Affects the ease of installation and routing of the cable
Tensile Strength Determines the cable’s ability to withstand pulling forces
Color Coding Aids in identifying different types of optical fibers in the cable


The choice of connectors for fiber optic cables is crucial in ensuring seamless connectivity between your network equipment. Understanding the compatibility between cable connectors and network equipment ports is key to achieving optimal performance and reliability.

For instance, if your network equipment features multi-fiber MTP ports, you will need fiber optic cables with the required number of fibers to enable connectivity. It’s important to check the specifications of your equipment and select the appropriate connectors accordingly.

In certain high-speed applications like 40GbE or 100GbE, Active Optical Cables (AOCs) offer an integrated solution by combining the optical fiber cable and transceivers into a single cable. This simplifies installation and maintenance, providing a streamlined solution for high-speed data transmission.

When choosing connectors, it’s crucial to ensure compatibility not only with your network equipment but also with the type of fiber optic cable being used. Different types of connectors, such as LC, SC, and ST, may be suitable for different cables and applications.

Factors to Consider when Choosing Connectors:

  1. Port Compatibility: Ensure the connectors match the ports on your network equipment.
  2. Cable Type: Consider the type of fiber optic cable being used and select connectors accordingly (e.g., LC connectors for single mode cables, SC connectors for multimode cables).
  3. Application Requirements: Evaluate the specific needs of your application, such as data speed, distance, and environmental conditions, to select connectors that meet these requirements.
  4. Quality and Reliability: Choose connectors that are known for their quality and reliability to ensure consistent performance and minimize the risk of signal loss or disruptions.

By selecting the right connectors and ensuring compatibility with your network equipment and fiber optic cables, you can create a robust and efficient network infrastructure.
