產品描述：
GYTA+33光纜結構是：光纖位于帶纖膏的松套管中；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。再經單細圓鋼絲鎧裝后，最后擠制聚乙烯外護層成纜。
The fibers 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 (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. The cable core is completed with aluminum polyethylene inner sheath, then the steel polyethylene outer sheath. After the single-steel wire armored, the cable is finally completed with an outer sheath.
光纜芯數范圍：2～144芯
Optical cable core number: 2 ~ 144core
