| 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 |
