層絞式非金屬加強芯非鎧裝光纜（GYFTY） Stranded Loose Tube Non-metallic Strength Member Non-armored Cable
·產品描述 Description
GYFTY 光纜的結構是將 250μm 光纖套入高模量材料制成的松套管中，松套管內填充防水化合物。纜芯的中心是一根玻璃纖維增強塑料（FRP），松套管（和填充繩）圍繞中心加強芯絞合成緊湊和圓形的纜芯，纜芯內的縫隙充以阻水填充物。 纜芯外擠上一層聚乙烯內護套成纜。
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 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 PE sheath.
