·产品描述Description

GYTA 光缆的结构是将 250μm光纤套入高模量材制成的松套管中，松套管内填充防水化合物。缆芯的中心是一根金属加强芯，对于某些芯数的光缆来说，金属加强芯外还需挤上一层聚乙烯（PE）。松套管（和填充绳）围绕中心加强芯绞合成紧凑和圆形的缆芯，缆芯内的缝隙充以阻水填充物。涂塑铝带（PL）纵包后挤制聚乙烯护套成缆。

The fibers, 250μm,are positioned in a loose tube made of a highmodulus plastic. The tubes are filled with a water-resistantfilling compound. A steel wire, sometimes sheathed withpolyethylene （PE） for cable with high fiber count, locates in thecenter of core as a metallic strength member. Tubes （and fillers）are stranded around the strength member into a compact and circularcable core. An Aluminum Polyethylene Laminate （APL） is appliedaround the cable core, which is filled with the filling compound toprotect it from water ingress. Then, the cable is completed with aPE sheath.
