Belden Inc. Outdoor OFC MLT: GLASS YARNS + PE with 12 Tubes of Ø2.5mm 216f SM OS2 G.657.B3. GBRFI16

The GBRFI16 is an outdoor dry core optical fiber Multi Loose Tube cable designed for various structured wiring applications. It features a construction of 12 tubes, each with a diameter of 2.5mm, containing a total of 216 single-mode fibers (9 tubes with 24 fibers each) compliant with OS2 G.657.B3 standards. The cable incorporates glass yarns for rodent protection and has a polyethylene outer jacket, making it suitable for direct burial and installation in ducts, tunnels, and trenches. This cable is rated for outdoor use in industrial, telecom, cable TV, and broadcast networks. It has a maximum attenuation of 0.30 dB/km at both 1550 nm and 1625 nm wavelengths. The operating temperature range is from -30 °C to +70 °C, with an installation temperature range of -5 °C to +50 °C. The cable is designed to withstand a maximum tensile strength of 6000 N during installation and 2000 N during operation, along with crush resistance ratings of 15 kN/m and 7.5 kN/m for short-term and long-term use, respectively. Overall, the GBRFI16 is a robust option for engineers seeking a reliable outdoor fiber optic solution with strong mechanical and environmental performance characteristics.
