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 ofaramid 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.
·产品特点 characteristics
· 非金屬的結構設計有效防止射頻干擾和電磁波干擾· non-mental design can prevent the cable from radio interference and magnetic wave interference· 特別設計的緊密的光纜結構，有效防止套管回縮· specially designed compact structure is good at preventing loose tubes from shrinking· 芳綸加強元件使光纜具有優異的抗拉性能·aramid yarn ensures good performance of tensile strength· 松套管內填充特種油膏，充分保證了光纜的防水性能·  loose tube filling compound ensure good moisture resistance performance· 具有良好的柔軟性· good flexibility· 光纖組裝密度高，纜徑小，重量輕，是氣吹敷設方式的*選擇· high dense fiber packed, small diameter and light weight; it's the better option for blowing installation process
·产品應用 application
利用微管資源，特別適用于骨干網，接入網和光纖到戶。adopted to backbone network, access network and fiber to the home.
