GCYFXY光缆结构是：光纤位于带纤膏的松套管中；套管先包上一层芳纶纱，再挤塑聚乙烯外护套。
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 layer of aramid yarn is applied around the tube as additional strength member. Then, the cable is completed with a HDPE sheath.
光缆芯数范围：2～24芯
Optical cable core number: 2 ~ 24 core
