Single mode or multimode fibres are position in a loose tube made of a high modulus plastic.The tube are filled with a water resistant filling compound.A steel wire,sometimes sheathed with ployethylene(PE) for cable with high fiber count,locates in the center of core as a metallic strength member.
Tubes (and fillers) are stranded around the strength member into a compact and circular cable core.the cable core is filled with filling compound to protect it from water ingress,over which a thin PE inner sheath is applied.After the PSP is longitudinally applied overthe inner sheath, the cable is completed with a PE sheath.
