3. Harsh Installation Conditions
In many cases, the installation of 5G networks requires fiber optic cables to be deployed in challenging environments such as underground conduits, subsea installations, or aerial cable routes. These environments pose unique challenges for network installation and maintenance, as fiber optic cables may be subjected to extreme tension, abrasion, or mechanical stress during installation.
Underground installations, in particular, are at risk of being disturbed by heavy machinery, rodents, or natural shifts in the terrain. In subsea installations, fiber optic cables must withstand the pressure of the water and potential damage from marine life or anchors. Aerial cables, on the other hand, are exposed to wind, rain, and ice, which can weaken the cable over time.
The armor in armored fiber optic cables serves as a protective barrier during installation in these harsh environments. It prevents the cable from being damaged by pulling forces or abrasions as it is laid in underground ducts or submerged in water. This ensures that the network can be installed without compromising the integrity of the fiber optics, reducing the likelihood of network downtime or the need for costly repairs.
4. Maintaining Network Reliability in Remote Areas
In rural or remote areas where 5G networks are being deployed, maintaining network reliability can be challenging due to the lack of infrastructure and support. These areas may be prone to wildlife interference, harsh weather conditions, and limited access for maintenance crews. Fiber optic cables in such environments must be able to withstand long periods without physical inspection or repair.
Armored fiber optic cables are ideal for these remote installations, as they are designed to provide long-term durability and protection. The armor shields the fiber core from potential damage caused by wildlife, such as rodents chewing through cables, or from extreme weather events that could weaken traditional cables. By using armored cables, network operators can ensure that 5G services remain reliable and operational even in areas with limited infrastructure and maintenance resources.
