Single-Armored Tight-Buffered Indoor Fiber Cable (Single-Mode, SFAC)

The FT-3898 from F-tone Networks is a single-mode indoor fiber cable with single armor and tight-buffered fibers, designed for protected indoor distribution. It is available in 1, 2, 4, 6, 8 and 12 fiber configurations, with the outer sheath diameter ranging from 3 mm up to 6 mm. Attenuation at +20 °C is specified at ≤0.36 dB/km at 1310 nm and ≤0.22 dB/km at 1550 nm, with a cable cut-off wavelength of ≤1260 nm. The armored construction gives the cable crush and rodent resistance beyond that of standard indoor tight-buffered designs, while staying compact for risers, plenums and equipment rooms. It fits campus backbones, building distribution and equipment interconnects where a protected single-mode feed is required indoors.
