Loose Tube Fiber Cable

Loose tube cables are optimized for outdoor applications.

Loose tube fiber cable.

They protect the fiber core cladding and coating by enclosing everything within semi rigid protective sleeves or tubes. 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. Each however is designed for very different environments. The gel within the loose tube construction stops the penetration of water and keeps it away from the fiber.

Loose tube fiber and tight buffered fiber. 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. Their designs utilize 250µm fibers in both central multi loose tube constructions ranging in fiber counts from 2 to 288. Fiber optic cables are constructed in two ways.

Loose tube cables the older of the two cable types are specifically designed for harsh outdoor environments. Loose tube and tight buffered. Both contain a type of strengthening member such as aramid yarn stainless steel wire strands or gel filled sleeves. Tight buffered and loose tube fiber are the two styles of constructions fiber optic cables offered.

Loose tube cables are designed for harsh environment conditions in the outdoors. 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. But there are two basic styles of fiber optic cable construction.
