OVERVIEW
OPTICAL FIBER CABLE
The number of fibers in a cable varies from 4 to 96 (more number of fibers are provided upon request). OPtical fiber cables will generally undergo 4 processes of production line such as Coloring Line, Secondary Coating Line, SZ-Stranding Line and Sheathing Line..
Optical Fiber Design
Each fiber is made of high purity Silica (SiO2) glass doped with Germanium (GeO2) and fused (SiO2) depressed cladding design for excellent geometrical properties for splicing and micro bending resistance. This fiber core is protected by two layers of UV - curred acrylate coating which is strong and durable enough to stand up to the challenge such as; micro bending losses, abrasion resistance, etc but remain easy to strip and splice.
Basic Cable Design
The cable core consist of stranded-six or eight thermal plastic elements with a central strength member. Elements couldbe either tubes, filler rods and or copper conductors. The coloured Polybutylene Terepthalate (PBTP) tube contains 4, 6, or 12 coloured fibers with its configurations (table 1 and 2) and water blocking compound to prevent moisture/water penetration and axial migration. Copper conductors, which stand for media of power supply for lighting, repeater, etc, are twisted in quad with cellular-solid insulation. The overall cable core is covered with flooding compound, water blocking tape and also protected by polyethylene sheathing.
