Product Description GYFTY53 Non Metallic Fiber Optic Cable Strong Moisture Resistance 1.Stranded Loose Tube Non-metallic Strength Member Light-armored Cable GYFTY53 Product Description: The fibers, 125μm, are positioned in a loose tube made of a high modulus plastic.The tubes are filled with a water-resistant filling compound. A Fiber Reinforced Plastic (FRP) locates in the center of core as a non- metallic strength member.The tubes (and fillers) are stranded around the strength member into a compact and circular core.After the cable core is filled with the filling compound to protect it from water ingress, the cable is completed with a thin polyethylene(PE) inner sheath. A layer of water- blocking tape is applied around the cable core to prevent water ingress all the same.After a corrugated steel tape armor is applied,the cable is completed with a PE outer sheath. 2. Features: ♦ Excellent mechanical and temperature performance ♦ Special tube filling compound ensure a critical protection of fiber and resist the water. ♦ Non-metallic central strength member FRP withstand axial loads. ♦ Inner sheath effectively lower the external mechanical loading. ♦ Corrugated steel tape longitudinal cover cable core and provide good crush resistance. ♦ PE sheath protects cable from ultraviolet radiation. ♦ 100% core filling water prevent cable jelly to ensure the cable watertight. 3. Application: ♦ Frequent lightning area and anti electric field : The subway, tunnel ♦Long-distance communication: Local trunk network & User network ♦ Duct and direct buried application ♦ Harsh environment 4.Optical Characteristics: Item G.652 G.655 50/125um 62.5/125um Attenuation @850nm ≤3.0dB/km ≤3.2dB/km @1300nm ≤1.0dB/km ≤1.2dB/km @1310nm ≤0.36dB/km ≤0.40dB/km @1550nm ≤0.22dB/km ≤0.23dB/km Bandwidth (Class A) @850nm ≥500MHZ.km ≥200MHZ.km @1300nm ≥1000MHZ.km ≥600MHZ.km Numerical aperture 0.200±0.015NA 0.275±0.015NA Cable cut-off wavelength ≤1260mm ≤1450mm Technical Parameters Cable Type Fiber Count Tubes Fillers Cable Diamete rmm Cable Weight kg/km Tensile strength Long/Short term (N) Crush resistance Long/Short term (N/100mm) Bending radius Static/Dynamic (mm) GYFTY53-2~6 2~6 1 5 12.0 155 1000/3000 1000/3000 12.5D/25D GYFTY53-8~12 8~12 2 4 12.0 155 1000/3000 1000/3000 12.5D/25D GYFTY53-20~24 20~24 4 2 12.0 155 1000/3000 1000/3000 12.5D/25D GYFTY53-32~36 32~36 6 0 12.0 155 1000/3000 1000/3000 12.5D/25D GYFTY53-38~48 38~48 4 2 12.0 155 1000/3000 1000/3000 12.5D/25D GYFTY53-50~60 50~60 5 1 12.0 155 1000/3000 1000/3000 12.5D/25D GYFTY53-62~72 62~72 6 0 12.0 155 1000/3000 1000/3000 12.5D/25D GYFTY53-86~96 86~96 8 0 13.8 170 1000/3000 1000/3000 12.5D/25D GYFTY53-134~144 134~144 12 0 16.8 205 1000/3000 1000/3000 12.5D/25D Environmental characteristics Operating temperature -40~+70℃ Storage temperature -40~+70℃ GYFTY53 Non Metallic Fiber Optic Cable Strong Moisture Resistance 0GYFTY53 Non Metallic Fiber Optic Cable Strong Moisture Resistance 1
