GYXTW 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。松套管外用一層雙面涂塑鋼帶（PSP）縱包，鋼帶和松套管之間加阻水材料以保證光纜的緊湊和縱向阻水，兩側放置兩根平行鋼絲后擠制聚乙烯護套成纜。

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. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape. The cable is completed with a polyethylene (PE) sheath.
