產品描述：
GYDTA光纜結構是：光纖帶位于帶纖膏的松套管中（光纖帶可以是4、6、8、12芯）；纜芯中心是鋼絲（可能會加PE墊層），鋼絲周圍由松套管、填充繩絞合而成，纜芯內、外的間隙填充纜膏；纜芯外為鋁聚乙烯護套。
The ribbon fibers are positioned in a loose tube made of a high modulus plastic.（The ribbon fiber may have 4，6，8，12 fibers.） The tubes are filled with a water-resistant filling compound. A steel wire (may PE blanket) locates in the center of core as a metallic strength member. Tubes 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 filling compound to protect it from water ingress. Then, the cable is completed with a PE sheath.
光纜芯數范圍：4～864芯
Optical cable core number: 4~ 864 core
