Optimizing Connectivity: The Efficient Fibramérica Square-Type Cable

Fibramérica revolutionizes connectivity with its square-type outdoor drop cable, ideal for last-mile installations in fiber optic networks. Its rounded-edge structure makes field handling easier, while the G.657A fibers ensure efficient transmission. The adjustable flammability LSZH sheath adds robustness. Compact in design and excellent in performance, it’s perfect for applications like FTTH and FTTB. 
This product is a reliable and durable solution for last-mile connections, standing out for its optimal price-performance ratio. Discover how it can transform your connectivity project.

Fibramérica’s outdoor drop cable (square type) is a drop cable specially designed for last mile installations in fiber optic networks that, thanks to its rounded edge structure, allows better handling in the field.

The cable consists of 1, 2 or 4 G.657A fibers with an attenuation coefficient of 0.4 dB/km at 1310nm and 0.3 dB/km at 1550nm. It has a tough and flexible black LSZH outer sheath. Its flammability level can be varied according to each need. It has a diameter of 5.0×2.0 mm and a weight of approximately 20 kg/km.

The cable is equipped with a metal messenger of 1.2, 1.0 or 0.8 mm diameter (depending on customer requirements), 2 metal reinforcement elements of 0.4 mm diameter or 2 FRP reinforcement elements of 0.5 mm diameter, which provide excellent resistance to external forces such as impact, bending and crushing.

The cable has an admissible short-term tensile strength of 600 N and an admissible long-term tensile strength of 300 N, considering a standard metallic messenger of 1 mm. It also has a short-term allowable crush resistance of 2,200 N/100 mm and a long-term allowable crush resistance of 1,000 N/100 mm. The minimum bend radius is 20.0x the cable diameter without tension and 40.0x the cable diameter under maximum tension.

Overall, Fibramérica’s square drop fiber optic cable is a reliable and durable option for outdoor installations requiring high-performance connectivity at an excellent price-performance ratio. Its compact design, robust construction and excellent technical specifications make it suitable for use in a wide range of applications, including fiber-to-the-home (FTTH), fiber-to-the-building (FTTB) and other last-mile connections.

• Cable resistant to deformation: Fibramérica’s drop cables stand out for their resistance to deformation in normal outdoor conditions. Thanks to a solid and well-designed structure, they provide reliable and long-lasting performance, consolidating themselves as the perfect choice for any installation.

• High-quality optical fibers: We use high-end fiber optic yarns, ensuring that our cables meet all essential requirements for an efficient and durable installation. All fiber optics are manufactured to the highest standards on the market.

• Highly resistant cable: The premium sheathing we use increases the fire resistance of the optical cable. In addition, it stands out for its remarkable tensile and torsional strength,facilitating installation in even the most confined spaces. Added to this, its exceptional bend resistance proves its robustness in all conditions.
