Fibre optic cables: laying and handling
Optical fibre cables, indoor and outside plant.
Every line names every source that states it and how it was seen; where sources disagree, each value is shown with its source. IEC, EN and HD documents and makers come first, national rules after them with their country.
Laying temperature and pre-warming
No value from a standard was found: use the maker's datasheet.
Bending radius
- About 15 times the outer diameter under load and 10 times without (Corning ALTOS: 215 mm and 143 mm on 14.3 mm; OFS loose tube: a bend diameter of 30 and 20 times). A product value: check the datasheet.Sources: Corning, OFS (maker's document)
Pulling force and method
- Armoured loose-tube cable of 12 to 72 fibres: 2700 N short-term (installation), 890 N long-term; industrial LSZH 48-fibre cable: 2700 N and 810 N. A product value: check the datasheet.Sources: Corning, OFS (maker's document)
