1. GYXTW Optical Fiber Cable（中心束管式室外光缆）
Description(产品描述)：
The fibers 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 corrugated steel tape. Between the corrugated steel tape 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.
GYXTW光缆的结构是将单模或多模光纤套入由高模量的聚酯材料做成的松套管中，套管内填充防水化合物。
松套管外用双面镀铬涂塑钢带纵包，钢带和松套管之间加阻水材料以保证光缆的紧凑和纵向阻水，两侧放置两根
平行钢丝后聚乙烯（PE）护套成缆。
Feature(产品特性)：
★ Double wire as strain member provides excellent strain performance.
★ Excellent mechanical performance.
★ Easy to installation and operation.
特性：适用于长途通信和局间通信，两根平行钢丝既起到抗张力作用，又起到抗侧压力作用，光缆机械性能好。
光缆外径小，重量轻，适宜施工。
Application(应用)：
★ Long distance and Local Area Network (LAN) communication.
★ GYXTW cable is suitable for aerial or conduit installation.
应用：管道，架空。
