Loose Tube Fiber Cable

But there are two basic styles of fiber optic cable construction.

Loose tube fiber cable.

Each however is designed for very different environments. Loose tube cables the older of the two cable types are specifically designed for harsh outdoor environments. Fiber loose tube cable belden s loose tube cables are ideal for both outdoor indoor outdoor applications including use in conduit direct burial lashed aerial trunking. The armoured loose tube cable is available with various constructions.

The configuration of loose tube cable comprises of a coated fiber placed within a loose tube which is filled with water resistant gel to protect fiber from tension and stresses caused by such harsh environment as moisture and a wide operation temperature range from thermal shock to ice loading. Loose tube cables are optimized for outdoor applications. Fiber optic cable is available in many physical variations such as single and multiple conductor constructions aerial and direct burial styles plenum and riser cables etc. Both contain a type of strengthening member such as aramid yarn stainless steel wire strands or gel filled sleeves.

These constructions will comprise of armouring to protect the optical fibers such as corrugated steel tape steel wire armouring steel wire braiding and others. Loose tube fiber and tight buffered fiber. Fiber optic cables are constructed in two ways. Loose tube cables whether flooded under the jacket or water blocked with dry swellable materials protect the fibers from moisture and the long term degradation moisture can cause.

Loose tube fiber cable will consist optical fibers in its construction. The global source for fiber optic products and solutions. This group of cable will come in many constructions deploying various jacketing materials and armour. Their designs utilize 250µm fibers in both central multi loose tube constructions ranging in fiber counts from 2 to 288.

Loose tube fiber optic cables hereinafter referred to as loose tube cables are the most widely used cables for outside plant trunks because they offer the best protection for the fibers under high pulling tensions and can be easily protected from moisture with water blocking gel or tapes these cables are composed of several fibers together inside a small plastic tube which are in turn wound. Loose tube and tight buffered.
