产品描述 Description 微型中心管式非金屬光纜是將250μm單模或多模光纖套入高模能量材料制成的松套管中,套管內填充無毒,無害的防水化合物,松套管外絞合非金屬加強元件芳綸或高強玻璃紗,再擠制黑色或彩色高密度聚乙烯(HDPE)護套成纜。
The fibers,250μm, either of single-mode or multimode type, 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 or high strength glass is applied around the cable core as additional strength member. Then, the cable is completed with a black or color HDPE sheath.
