Belden FSSL012ND, 12 F FX OS2 Outdoor OSP Dry Tube Black Jacket

Belden FSSL012ND is an outdoor, all-dielectric OS2 loose tube fiber optic cable with 12 fibers and a gel-free dry tube design. It uses a PE - Polyethylene jacket in black and includes Waterblock Tape for cable core water blocking. Optical characteristics include max. attenuation of 0.35 dB/km (1310 nm) and 0.25 dB/km (1550 nm). For handling and installation, it maintains a minimum bend radius of 15x Cable OD during installation and 10x Cable OD during operation.
