The FT-108 3mm Two-Core Single-mode Armored Fiber Optic Cable V3.06 is a 3mm outer diameter indoor / special application single-mode armored fiber optic cable manufactured by F-tone Networks(北亿纤通). The cable adopts a 4-layer composite structure: 2-core G657A2 single-mode bare fiber as the core transmission medium, stainless steel armor tube as inner mechanical protection, aramid fiber (Kevlar) as tensile reinforcement layer, and TPU outer sheath as external environmental protection. With cladding diameter 124.8±0.7μm, coating diameter 245±5μm, cutoff wavelength ≤1260nm, and attenuation coefficient ≤0.4dB/km @ 1310nm / ≤0.3dB/km @ 1550nm. The cable provides tensile strength 120N (long term) / 150N (short term), operating temperature -45°C to +85°C, and minimum bend radius 20D (dynamic) / 15D (static). For indoor communication, special application, military communication, harsh environment communication, and bend-insensitive single-mode fiber applications.
