Fiber Optic Loose Tube Vs Tight Buffered

The acrylate coating keeps moisture away from the cable as the gel filled sleeves do for loose tube cables.

Fiber optic loose tube vs tight buffered.

Both contain a type of strengthening member such as aramid yarn stainless steel wire strands or gel filled sleeves. Tight buffer or tight tube cable designs are typically used for isp applications. Fiber optic cables are constructed in two ways. Loose tube fibers are designed for harsh environmental conditions in the outdoors.

Loose tube fiber optic cable is typically used for outside plant installation in aerial duct and direct buried applications. Each however is designed for very different environments. In loose tube cables the coated fiber floats within a rugged abrasion resistant oversized tube which is filled with optical gel. Loose tube cables are designed for harsh environment conditions in the outdoors.

However in tight buffered cables there are not so many cables as loose tube fibers. Between them there are several common denominators like the fact that both have in their interior a strengthening member of sorts that can be made of stainless steel in the form of wire strands aramid yarn or gel filled sleeves. Tight buffer fiber contains a thick coating of a plastic type material which is applied directly to the outside of each individual fiber. Loose tube and tight buffered.

Loose tube fiber contains multiple strands of fiber in a single jacket. Each fiber is coated with a buffer coating usually with an outside diameter of 900m. The other is waterproof acrylate. In loose tube cables a high level of isolation from water penetration and extreme temperatures are possible while tight buffered cables being more robust than loose tube cables are better suited for lan or wan connections long indoor runs and direct burial.
