1) The type of this fiber with single-mode or multi mode with a loose tube which is made of high modulus plastic .there is used a water-resistant filling compound for filling.
3) the center used a steel wire locates as a metallic strength member .for some cable ,a steel wire sometimes sheathed with polyethylene .the tubes ( and filers ) are stranded around the strength member into a compact and circular cable core.double sides chromium for PSP with PE as sheath .
3) by single or double wire for installation ,also with PE for outer sheath.
♦ PE outer sheath provide excellent ultraviolet radiation resistant property
♦ After the optical fiber ,the additional attenuation close to zero,no changed dispersion.
♦ Good moisture-resistance
♦ Control of fiber excess length stability.
