·产品描述 description
ftth室內光纜是將光通信單元處于中心，兩側放置兩根平行非金屬加強元件（frp），在外側再附加一根鋼絲加強元件，最後，擠制黑色或彩色低煙無鹵護套成纜。 the optical fiber unit is positioned in the centre. two parallel fiber reinforced plastics (frp) are placed at the two sides. a steel wire as the additional strength member is also applied. then the cable is completed with a black or color lszh sheath.
