The structure of optical cables evolves alongside the development of optical networks and the requirements of their operating environments. The new generation of all-optical networks demands that optical cables provide wider bandwidth, support more wavelengths, transmit at higher speeds, facilitate installation and maintenance, and have a longer lifespan. The emergence of new materials for optical cables has also driven improvements in cable structure, such as the use of water-blocking materials, nanomaterials, and flame-retardant materials, which have significantly enhanced the performance of optical cables. In recent years, emerging optical cables have appeared, including eco-friendly optical cables, nanotechnology optical cables, and micro-optical cables.
Eco-friendly optical cables: Primarily from an environmental protection perspective, these cables address the problem of non-eco-friendly materials in optical cables, such as the release of toxic gases from burning PVC and lead from the cable's stabilizers. These optical cables are mainly used indoors in buildings and homes. Currently, some companies have developed new materials for these optical cables, such as halogen-free, flame-retardant plastics.
Nanotechnology optical cable: Optical cables that utilize nanomaterials (such as nanofiber coatings, nanofiber ointments, nano-coated polyethylene, and nanoPBT optical fiber coating) take advantage of many excellent properties of nanomaterials, such as improving the performance of optical fibers and their mechanical resistance to impact.
Micro-optical cable: Micro-optical cable is primarily used in conjunction with air-pressure or water-pressure installation and construction systems. Various micro-optical cable structures have been designed and implemented. There is a specific relationship between the optical cable and the conduit, and the cable's weight, strength, and other factors must be carefully considered for safety. To meet the needs of future access networks, micro-optical cable and automated installation methods are being integrated into the cabling systems of customer premises networks and smart building conduits.
In summary, with the development of superior technology in optical networks, optical cables continue to improve in terms of structure, new materials, and performance enhancements to meet the diverse needs of future communications, such as massive data transport and massive connectivity in 5G.
