Loose Tube Fiber Optic Cable

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.

Loose tube fiber optic cable.

Suitable for lashed aerial duct underground conduit environments. Loose tube fiber this type of cable is designed for the outdoors. Since the tube does not have direct contact with the fiber any cable material expansion or contraction will not cause stress on the fiber. Each however is designed for very different environments.

Loose tube cables are designed for harsh environment conditions in the outdoors. Most loose tube fiber optic cables are available with either gel free or gel filled tubes. Their designs utilize 250µm fibers in both central multi loose tube constructions ranging in fiber counts from 2 to 288. Loose tube cables the older of the two cable types are specifically designed for harsh outdoor environments.

Fiber optic cablesare constructed in two ways. The loose tube design isolates the fibers from outside environmental and mechanical stresses. Need custom fiber cable. Both contain a type of strengthening member such as aramid yarn stainless steel wire strands or gel filled sleeves.

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. Although the end performance is essentially the same there are some key differences in construction. Loose tubeand tight buffered. Cables that are on the outside are continuously stressed by a plurality of environmental conditions that could affect their integrity and performance.

In loose tube cables the coated fiber floats within a rugged abrasion resistant oversized tube which is filled with optical gel. Overall loose tube fiber optic cables offer the best protection in an outdoor environment especially in the less sheltered applications involving aerial or direct buried installations.
