With the rapid advancement of modern communication technology, fibre optics has become the backbone of data transmission. Whether for long-distance network connections or local setups, fibre optics offers high-speed and stable communication solutions. Among the various types of fibre optic cables, armoured fibre optic cables and non-armoured fibre optic cables are two of the most commonly used options. This article will explore the main differences between these two types of cables. Helping you make the best choice based on your specific needs.
What Are Armoured and Non-Armoured Fibre Optic Cables?
- Armoured Fibre Optic Cable An armoured fibre optic cable is equipped with an additional protective layer made of metal (typically steel or aluminium) around the core of the cable. This protective layer is designed to enhance the cable's resistance to pressure, tension, and impact, preventing physical damage from external factors.
- Non-Armoured Fibre Optic Cable A non-armoured fibre optic cable, on the other hand, lacks this additional metal protection. It typically has a plastic outer sheath that provides basic protection. While it is lightweight and flexible, it may be more vulnerable to physical damage or external pressures in harsher environments.
Key Differences Between Armoured and Non-Armoured Fibre Optic Cables
1. Physical Protection
- Armoured Fibre Optic Cable: The metal protective layer of armoured fibre optic cables provides robust resistance to physical pressure, stretching, and mechanical impacts. This makes them ideal for installation in underground, industrial, or high-risk areas where the cable may be exposed to potential physical harm.
- Non-Armoured Fibre Optic Cable: Non-armoured cables, with only a plastic sheath for protection, have lower resistance to physical damage. They are better suited for environments where the cable is less likely to face mechanical stresses. Such as in indoor settings or stable external conditions.
2. Flexibility and Installation Difficulty
- Armoured Fibre Optic Cable: Due to the metal armouring, armoured fibre optic cables are usually more rigid and less flexible than non-armoured ones. You may need to put in more effort to install them, especially when tight bends or narrow spaces are involved.
- Non-Armoured Fibre Optic Cable: Non-armoured fibre optic cables are lighter and more flexible, making them easier to handle and install. You can choose them when you need to bend or adjust the cable frequently during installation.
3. Cost Differences
- Armoured Fibre Optic Cable: The additional metal armouring and more complex manufacturing process result in higher costs for armoured fibre optic cable. Although they provide superior protection, they can cost significantly more, especially when you require large-scale deployment.
- Non-Armoured Fibre Optic Cable: Non-armoured cables are simpler to manufacture and use less expensive materials, making them more cost-effective. They are a good choice when budget constraints are a priority, and the environment does not require extra protection.
4. Environmental Suitability
- Armoured Fibre Optic Cable: Armoured cables are ideal for harsh environments, especially where physical damage or external forces are a concern. People typically use these cables in underground installations, industrial sites, or areas prone to tampering, such as construction zones.
- Non-Armoured Fibre Optic Cable: Non-armoured cables are best suited for controlled environments. Such as indoor installations or areas where the risk of physical damage is minimal. They are also a good choice for applications where flexibility and ease of installation are important.
