How OFNR and LSZH optic cables are different

Fiber optic cables are replacing the traditional copper cables rapidly and improving the speed and signal transmission rates. Now and then, every organization and other fields are replacing copper cables with fiber optic cables. For having better results, it is important to take expert help in installing the cable. The cable installation is a very critical and important step. Apart from the installation, the other important factor to consider is the type of cable. The fiber optic cables have a variety of types, and each serves different purposes.

Every type of fiber optic cable has a unique appearance and look. It is because of the type of the outer jacket or the inner cladding. Depending upon your need, choose the right cable for yourself. Some cables have a higher tendency to resist the moisture and temperature differences, while some have a lower tendency.

Below are the two fiber optic cable types and their difference. Keep reading the paragraphs below to understand the use and nature of these two types of cables.

The main difference between OFNR and LSZH fiber optic cables

These are the two most commonly used types of fiber optic cables. Both of these cables serve different purposes and fulfill different needs. The full form of these two cables and their use is as follows.

OFNR Fiber Optic Cable:

OFNR or optical fiber, nonconductive, riser are used in building as they tend to stop the fire from spreading from one building floor to another. Such cables have components within them that help not to conduct electricity.

The tendency to resist fire in OFNR is lower as compared to OFNP. OFNR emits black smoke when it burns that is why ventilation systems and fire exits are necessary if the building has optical fiber nonconductive riser installation

LSZH Fiber Optic Cable:

LSZH stands for low smoke zero halogen as the name itself shows that these cables emit less smoke when they burn. When such cables get exposed to high temperatures or heat, they emit fewer radiations and smoke. This property makes them healthy to use in terms of not affecting people’s health. LSZH cable jackets are composed of a thermoplastic or thermoset that resists smoke and halogen emission when they get exposed to high heat or any flames.

When to use these types of cables?

From the difference between these two cables in the above paragraphs, it is evident that which cables are suitable to use under which circumstances. It is good to use LSZH cables to feel that the temperatures are a bit higher and risk human health. In areas that have no ventilation systems and fire exits, it is important to use LSZH cables. The most common use of such cables is indoors and in the tunnels.

ONFR cables are useful in riser applications. Some people use them in the buildings too, but it is obligatory to have proper ventilation systems before installing them. For avoiding an accident, it is important to understand the type of cable you are using and where to use them. Hiring fiber optic companies in Dubai while installing the network cables or choosing the type of cable will help you reach the cables that are the best fit for you and your needs.

What are the other types of fiber optic cables?

Apart from the above two fiber optic cables, multiple fiber optic cable types are in use. Each of the cables has its specific properties in working, resisting heat and temperature factors and reliability. The things that differentiate these types of cables are the cable’s inner components, the cladding, and the type of outer jacket. Below is a list of some of the types of fiber optic cables.

  • OFN (Optical fiber nonconductive)
  • OFC (Optical fiber conductive)
  • OFCP (Optical fiber nonconductive plenum)
  • OFNP (Optical fiber nonconductive plenum)
  • OFCG (Optical fiber conductive general use)
  • OFNG (Optical fiber nonconductive general use)
  • OSP (Optical outside plant)

Why fiber strength and reliability are important?

For getting better results, the network cables must be reliable. The strength of a cable degrades with time. There are multiple reasons for the degradation in the strength of the cables. One of the main reasons is the mishandling of the fiber while installing it. That is why it is always good to hire experts and their teams to install and manage the fiber cables. Hire fiber optic companies in Dubai to install the fiber optic cable with great care without affecting its strength and reliability.

Replacing fiber over copper cables

Fiber optic cables are rapidly replacing the old traditional and heavy copper cables. The coming years are of speed, and people demand networks that provide high speeds for data transmission. Apart from the speed of the data, the security of your data is also important. Fiber optic cables have multiple types of cables that will safely transmit your data without affecting the people, their health and their resources. Make the right choice of the fiber cable from the different types available.
