标题: FTTH 普通入户光缆 FTTH Cable (GYXTPY )
·产品描述 Description

GYXTPY光缆的结构是将 250μm 光纤套入高模量材料制成的松套管中，松套管内填充防水化合物。两侧放置两根平行钢丝后挤制聚乙烯护套成缆。

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. Two parallel steel wires are placed at the two sides of the steel tape. The cable is completed with a polyethylene (PE) sheath.
