Рисунок 8 волоконно-оптических кабельных GYTC8S

RNG figure 8 optical fiber cable--GYTC8S · Description:The fibers, 250µm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire locates in the center of core as a metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular cable core. After the PSP moisture barrier is longitudinally applied over the cable core, this part of cable accompanied with the stranded wires as the supporting part are completed with a polyethylene (PE) sheath to be figure 8 structure.RNG figure 8 cable GYTC8Y, GYTC8A are also available on request. This type of cable is specially applied for self-supporting aerial installation.· Features:-- High tensile strength of stranded wires meet the requirement of self-supporting and reduce the installation cost.-- Good mechanical and temperature performance-- High strength loose tube that is hydrolysis resistant-- Special tube filling compound ensure a critical protection of fiber-- The following measures are taken to ensure the cable watertight- Steel wire used as the central strength member- Loose tube filling compound- 100% cable core filling- PSP enhancing moisture-proof· Technical Parameters:TypeFiber CountStranded UnitsOutside Diameter (mm)Cable Weight (kg/km)TensileCrushBendingTemperature(oC)S(N)L(N)S(N)L(N)GYTC8S-044611.6/25.5270.0900040003000100020D/10D-40 +70GYTC8S-066GYTC8S-088GYTC8S-1212GYTC8S-2424GYTC8S-3636GYTC8S-4848GYTC8S-727212.8/27.5300.0GYTC8S-9696814.6/31.5390.0100005000GYTC8S-1441441218.8/35.0440.0120006000· Optic Characteristics:Fiber TypeG652G65550/125µm62.5/125µmAttenuation(+20 oC)850nmNoNo≤3.0 dB/km≤3.0 dB/km1300nmNoNo≤1.0 dB/km≤1.0 dB/km1310nm≤0.36 dB/km≤0.40 dB/kmNoNo1550nm≤0.22 dB/km≤0.23 dB/kmNoNoBandwidth (Class A)850nmNoNo≥600 MHz·km≥200 MHz·km1300nmNoNo≥1200 MHz·km≥600 MHz·kmCable Cut-off Wavelength≤1260nm≤1450nmNoNoRemarks: Also making following customer's request.
