Belden Inc. Indoor/Outdoor LSZH/Riser OS2 Distribution 48Fibers FDSD048LK

The FDSD048LK is an Indoor/Outdoor LSZH/Riser OS2 Distribution cable featuring 48 fibers organized into four subunits of 12 fibers each. The cable is designed for premise backbone applications and utilizes low smoke zero halogen (LSZH) materials for safety in environments where smoke emissions must be minimized. The fiber type is OS2 with a core diameter of 8.2/125 ¬µm, and it has a maximum attenuation of 0.50 dB/km at both 1310 nm and 1550 nm wavelengths. The cable supports 1 Gigabit Ethernet performance up to 5,000 meters and 10 Gigabit Ethernet performance up to 10,000 meters. Constructed with waterblocking aramid yarns for strength and protection, the cable has a nominal outer diameter of 0.688 inches (17.5 mm) and is rated for a temperature range of -40¬8C to +70¬8C during operation. It meets various compliance standards, including OFNR and FT4 for flammability, and is suitable for burial and sunlight exposure. Engineers considering this product should note its robust mechanical characteristics, including a minimum bend radius of 15 times the cable diameter during installation and a tensile strength of 800 N during operation.
