Loose Tube Cables

Since the tube does not have direct contact with the fiber any cable material expansion or contraction will not cause stress on the fiber.

Loose tube cables. They protect the fibercore cladding and coatingby enclosing everything within fairly rigid protective sleeves or tubes. Suitable for lashed aerial duct underground conduit environments. Their designs utilize 250µm fibers in both central multi loose tube constructions ranging in fiber counts from 2 to 288. 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.

In loose tube cables the coated fiber floats within a rugged abrasion resistant oversized tube which is filled with optical gel. Loose tube cables con also be found filled with a water resistant gel that surrounds every fiber it contains. Loose tube cables the older of the two cable types are specifically designed for harsh outdoor environments. This gel s main purpose is to protect the fibers from moisture which makes them the ideal choice if you happen to live in a harsh environment with high humidity where h2o and water condensation can be a major problem.

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. They protect the fiber core cladding and coating by enclosing everything within semi rigid protective sleeves or tubes. Belden s loose tube cables are ideal for both outdoor indoor outdoor applications including use in conduit direct burial lashed aerial trunking. 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.
