Accessories
loose tube primary coated optical fibres are loosely encapsulated.Fibre Optic secondary coating
Communication technology
All fibres have secondary protection added before stranding.
There are different fibre optic cable tubes: tight buffer semi tight buffer mini bundle loose tube
tight buffer
Copper screened
The fibre tightly jacketed with thermoplastic over sheath. The secondary protection consist one layer termoplastic material. The advantages the semi tight buffering compared with the tight buffering are: The tube can easily stripped Minimal effect microbending

4 optical fibres are loosely encapsulated. The spare room between fibre and loose tube only few hundreths millimeter. The tube consist one two layers the same different materials.
