All-Dielectric Sensing Cable

Product description: The lightweight two-core ultra-soft vibration sensing cable is a cable with excellent mechanical performance and light weight, specially designed for rapid field cabling and reeling applications. The cable consists of tight-buffered optical fibers, Kevlar strength members and a PU outer sheath, with a very simple structure. Thanks to high-modulus Kevlar (aramid) and special elastic PU materials, this cable offers excellent mechanical performance and relatively light weight, withstands various harsh field environments, and can be repeatedly deployed and retrieved. It can be used for military field cabling, rapid repair of communication cables, temporary mobile cabling and other applications, as well as permanent cabling systems.

Product features

Uses high-strength fatigue-resistant optical fiber, ensuring the reliability and service life of the field cable under various harsh service conditions.
The tight buffer uses HYTROL material of a certain hardness, which ensures the fiber crush resistance and improves fiber sensitivity to vibration.
Uses extremely strong and lightweight Kevlar as the strength member, giving the cable high tensile characteristics.
The flame-retardant high-strength, high-toughness polyurethane (PU) elastomer sheath has a high oxygen index and good flame retardancy, and is resistant to oil and chemical corrosion, tear-resistant, flexible at low temperatures, highly elastic, wear-resistant and crush-resistant.

Applications

Mobile communication systems
Distributed micro-vibration sensing
Can be installed aerially, shallow-buried, in ducts, or surface-mounted along walls, fences, etc.
