Fibre Optic secondary coating
Communication technology
All fibres have secondary protection added before stranding. The overall diameter 1,8 3,5mm depending fibre counts

Informations
Technical changes reserved. The spare room between fibre and loose tube only few hundreths millimeter. The overall diameter approxiately 0,95 1,4mm. The overall diameter the semi tight buffer identical with the diameter the tight buffer. The interstices inside the tube are filled with gel. The secondary protection consist one layer termoplastic material.
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.
Accessories
loose tube primary coated optical fibres are loosely encapsulated. The tube consist one two layers the same different materials.

filling compound optical fibre semi tight buffer
The fibre semi loosely jacketed tube polymer material. The advantages the semi tight buffering compared with the tight buffering are: The tube can easily stripped Minimal effect microbending
