Fiber Optic Cable with TPU Jacket

Thermoplastic polyurethanes (TPU) are a class of polyurethane plastics with many exceptional properties including elasticity, high tear strength, and resistance to oil, grease, corrosion and abrasion, low temperature performance over a wide range, especially suitable for some usage in harsh environments and under most rugged mechanical demands such as industrial equipment, ships, aerospace instruments, polar environments, etc.

As one type of the fiber cable jacket material, it requires tough enough to protect the fiber inside. The fiber optic cable are usually require following function features:

1. The design and construction of Optical fiber cable shall be inherently robust and rigid under all conditions of installation, operation, adjustment, replacement, storage and transport.
2. The Optical fiber cable shall be able to work in a saline atmosphere in coastal areas and should be protected against corrosion.
3. Life of cable shall be at least 25 years, based upon life of the fiber and other component parts of the cable. The cable shall meet the cable aging test requirement.
4. It shall be possible to operate and handle the optical fiber cable with standard tools. If any special tool is required for operating and handling the optical fiber cable the same shall be provided along with the cable.
5. The optical fiber optic cable shall be suitable and compatible to match with the dimensions, fixing, terminating & splicing arrangement of the splice closure. The cable supplied shall also meet other requirement of splice closure.
6. The optical and mechanical fiber characteristics shall not change during the lifetime of the cable against the manufacturing defects.

The characteristics of materials used in the jacket play a key role in whether the cable will pass the particular test like IEC 60974 such as abrasion, crush, impact, repeated, torsion, cable bend, temperature cycling tests. As the development of the TPU material, it is expected to contribute to meeting the requirement.

Field fiber cable like tactical fiber optic cable usually use TPU material to have features including excellent flexibility, very convenient for construction wiring, higher tensile strength, wear-resistant. The fiber optic cable is suitable for repeated retractable wiring environment, such as stage TV live mobile wiring, military Communication fast wiring, emergency communication repair, etc. Some of the more demanding military field cables will also replace the material of the sub-cables with ordinary PVC/LSZH for higher strength nylon (Nylon) to make its performance more stable.

We are providing a range of indoor/outdoor tactical fiber optic cable with TPU jacket for your various purporse in different structures.
