Cable Jetting
Cable jetting is a technique to install cables in ducts. It is commonly used to install cables with optical fibers in underground polyethylene ducts and is an alternative to ''pulling''. Pulling Traditionally, fibre optic cables were pulled through cable ducts in the same way as other cables, via a winch line. Every time the fibre passes a bend or undulation in the duct, the pulling force is multiplied by a friction-dependent factor (which can be reduced by using lubricant). This means that the higher the local pulling force is, the more friction the cable will experience while being pulled against the internal duct wall. This "capstan effect" leads to an exponential force build-up with pull distance, producing generally high pulling forces. Jetting Cable jetting is the process of blowing a cable through a duct while simultaneously pushing the cable into the duct. Pneumatics, Compressed air is injected at the duct inlet and flows through the duct and along the cable at high speed ...

Jet (lignite)
Jet is a type of lignite, the lowest rank of coal, and is a gemstone. Unlike many gemstones, jet is not a mineral, but is rather a mineraloid. It is derived from wood that has changed under extreme pressure. The English noun ''jet'' derives from the French word for the same material, (modern French ), ultimately referring to the ancient town of Gagae. Jet is either black or dark brown, but may contain pyrite inclusions which are of brassy colour and metallic lustre. The adjective " jet-black", meaning as dark a black as possible, derives from this material. Origin Jet is a product of decomposition of wood from millions of years ago, commonly the wood of trees of the family Araucariaceae. Jet is found in two forms, hard and soft. Hard jet is the result of carbon compression and salt water; soft jet may be the result of carbon compression and fresh water. Despite the name they both occupy the same area of the Mohs scale with the difference being that soft jet is more likely to ...
