Overview

Product details

The FT-3900 is a 1-fiber single-mode single-armored FTTH duct cable built to the GJFDC construction for underground installation inside protective ducts. A metal strength member supplies robust tensile and crush resistance for demanding duct pulls and buried routes. A single armor layer adds further protection for the fiber unit during installation and in service. The single-mode fiber achieves attenuation of ≤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 LSZH outer jacket is flame-retardant with low smoke emission where the cable transitions toward buildings. The cable outside diameter is 7 mm for 1 to 2 fiber versions.
