    Specifications for FTTH Cable
    Overall structure for FTTH Cable FTTH Cable has a rectangular cross section structure
    Colored optical fiber code 1FO/2FO/4FO
    Cladding Material LSZH plastic
    Thickness Average 0,8mm ± 0,1mm
    Cladding is made of high quality LSZH, composed of carbon (light yellow color for lines running inside the home), UV – resistant, contains suitable antioxidant, does not develop mildew, electrical insulation.
    Cladding protects the core from mechanical and environmental forces during storage, assembly and operation (water, heat, chemicals, insect bites,…)
    Subscriber line coating is smooth, concentric, without  connecting points, without cracks, without holes, of even quality ( not rough, does not have bubbles, not divided, no bumps, no holes, no lumps), does not contain metal; flexible, firm, easy to open; optical fiber does not stick to coating when opening; sleeve thickness is even along cable length.
    Separating the hanging wire from the cable does not change the structure of cable nor affect the quality of optical fiber in it
    Additional reinforcing component (Bearing wire )

     

    Material zinc – coated single steel wire
    Diameter ³ Ø 0,4 mm
    Number of wire 2 zinc – coated steel wire placed on both sides to protect optical fiber
    Hanging wire Material zinc – coated steel wire : steel wire tape (7 wires x ≥ Ø 0,33mm)
    Sleeve LSZH plastic

    Average thickness  0,5mm ± 0,1mm
