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.
