Detailed Description
Description: Outdoor optical fiber cable (GYTA53) GYTA53 optic fiber cable complies with Standard YD/T 901-2001as well as IEC 60794-1 Outdoor optic fiber cable (GYTA53) The excellent performance fibers,which is positioned in a loose tube made of a high modulus plastic -PBT. The tubes are filled with a water blocking jelly. A steel wire,sometimes sheathed with polyethylene (PE) for cable with more fibers count,locates Central Strengthen Member.Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. An Aluminum Polyethylene Laminate (APL) is applied around the cable core,which is filled with the water blocking compound to protect it from water ingression.The cable core is covered with longitudinal corrugated aluminum tape and steel tape improves crush resistance of the cable. According to the requirement of customers ,adding the rip cord ,or change the water compound into water blocking tape. Characteristics 1.Excellent mechanical and temperature performance. 2. High strength loose tube that is hydrolysis resistant 3.Tube filling jelly compound ensure a critical protection of fiber from hydrogenation. 4.Crush resistance and flexibility 5.Steel wire used as the central strength member 6.100% water blocking compound filled with the cable core. 7.APL moisture barrier. 8.PSP enhancing moisture-proof. 8. Water-blocking material. Characteristic of Optical Fiber G652D Mode field diameter (1310nm): 9.2m0.4m Mode field diameter (1550nm): 10.4m0.8m Cladding diameter: 125m1.0m Core/cladding concentricity error: 0.6m Cladding non-circularity: 1.0% Refractive index profile: step Design: matched cladding Effective group index of refraction Neff (at 1310nm): 1.4677 Effective group index of refraction Neff (at 1550nm): 1.4682 Cut off wavelength of cabled fiber (CC): 1260nm Attenuation at 1310nm: 0.35dB/km Attenuation at 13833nm: 0.34dB/km Attenuation at 1550nm: 0.21dB/km The loss increase of 100 turns of fiber loosely wound with 30mm radius: 0.05dB Dispersion in the range 1288 to 1339nm: 3.5ps/(nm•km) Dispersion at 1550nm: 17.9ps/(nm•km) Dispersion slope at zero dispersion wavelength: 0.092ps/(nm2•km) Polarization mode dispersion link value: 0.1ps/km Temperature requirement Operation - 40℃ ~ +70℃ Installation - 30℃ ~ +60℃ Storage/transportation - 40℃ ~ +70℃ Temperature cycling test conform to IEC 794-1-F1 Bending Radius unloaded 10 times of outer diameter loaded 20 times of outer diameter
