Polycarbonate, a versatile and durable thermoplastic polymer, finds extensive applications in Optical Distribution Networks (ODNs), particularly in the realm of fiber optic cables. One crucial application lies in the use of polycarbonates for buffer tubes within these cables. The choice of polycarbonate for buffer tubes is attributed to its exceptional properties. Firstly, its dimension stability and lower post-contraction characteristics provide a substantial advantage, allowing for a wider operating temperature range. This is crucial in optical distribution networks where cables may be exposed to diverse environmental conditions. The ability to withstand varying temperatures ensures the reliability and longevity of the fiber optic cables.
Another key attribute is the impact resistance and stiffness of polycarbonate. These properties are essential when laying cables, as they contribute to the structural integrity and protection of the delicate fiber optics within. Polycarbonate grades such as Makrolon® 3208 (extrusion grade) or the polycarbonate blend Bayblend® FR3030 are used for this specific application.
Transparent polycarbonates play a crucial role in microduct connectors, featuring a robust design with IP68 protection against water infiltration and resistance to high pressure forces. Ideal for underground cable installation, these connectors have a transparent body for easy visual inspection, while the impact resistance and durability of polycarbonates make them ideal for ensuring the longevity and reliability of the connectors.
Polycarbonates extend their influence to the housing materials for cable enclosures within ODNs. Their impact-resistant nature and durability make them a preferred choice, providing robust protection for the intricate network components against external factors.
Furthermore, Fiber Access Terminal Boxes (FATBs) benefit from the use of polycarbonate in their housing and splice tray. The dimension stability and durability of polycarbonate prove instrumental in maintaining the structural integrity of these vital components, ensuring the efficient functioning of the fiber optic network. Covestro offers materials for both indoor and outdoor applications.
Shorter version if needed: The applications of polycarbonates in Optical Distribution Networks, from buffer tubes to connectors and enclosures, are grounded in their unique combination of properties such as dimension stability, impact resistance, and durability. These characteristics collectively contribute to the reliability and robustness of fiber optic communication systems, making polycarbonates a material of choice in the ever-evolving landscape of optical networks.
