1-Fiber Single-Mode Single-Armored FRP LSZH FTTH Duct Cable

The FT-3904 is a 1-fiber single-mode single-armored FTTH duct cable built to the GJFDC construction for underground installation in protective ducts. An FRP (fiberglass-reinforced plastic) strength member gives the cable tensile strength without any metallic components, keeping it immune to electromagnetic interference along the route. A single armor layer shields the fiber unit during duct pulling and in-service protection. The single-mode fiber delivers 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, and the cable outside diameter is 7 mm for 1 to 2 fiber versions.
