Loose Tube Fiber Optic Cable

Loose tube cables are designed for harsh environment conditions in the outdoors.

Loose tube fiber optic cable.

Most loose tube fiber optic cables are available with either gel free or gel filled tubes. Suitable for lashed aerial duct underground conduit environments. Since the tube does not have direct contact with the fiber any cable material expansion or contraction will not cause stress on the fiber. They protect the fiber core cladding and coating by enclosing everything within semi rigid protective sleeves or tubes.

Both contain a type of strengthening member such as aramid yarn stainless steel wire strands or gel filled sleeves. All multimode and singlemode cables except om1 utilize bend insensitive optical fibers and has gel filled loose tubes to provide protection against water penetration and dry super absorbent polymers saps to eliminate water migration in cable interstices. Although the end performance is essentially the same there are some key differences in construction. In loose tube cables the coated fiber floats within a rugged abrasion resistant oversized tube which is filled with optical gel.

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. Cables that are on the outside are continuously stressed by a plurality of environmental conditions that could affect their integrity and performance. The loose tube design isolates the fibers from outside environmental and mechanical stresses. Loose tube cables the older of the two cable types are specifically designed for harsh outdoor environments.

Loose tube fiber this type of cable is designed for the outdoors. Fiber optic cablesare constructed in two ways. Loose tubeand tight buffered. Each however is designed for very different environments.
