Industrial Cable Manufacturer

Structure of Stranded Loose Tube Ribbon Fiber Cable The buffer tuber is a kind of thermoplastic material and is made of polypropylene can nylon. The loose tube can be put in fiber cable loosely and protect optical fiber from interior stress and outer side pressure.
Optical fiber ribbon
Filler: thermo softening material
The optical gel is filled in optical cables before they completed and sheathed to pass water proof tests and infiltration tests.
The central strength member: high-count fiber cable and extruded polyethylene.
The water proofing material: filling compound.
The damp-proof layer: the aluminum-plastics tape can protect cable from damp.
The outer jacket uses black polyethylene and is easy to lay and transport. Description of Stranded Loose Tube Ribbon Fiber Cable

We insert a single-mode or multi-mode into the loose tube made of high modulus polyester material and filled with water proof compounds. The center of cable core is a metallic strength core. For the cables with a certain number of cores, the metallic strength core sheathed with polyethylene (PE). The loose tube (and filling rope) is twisted around the central strength core to form a compact circular core, whose cracks are filled with water blocking materials. Extruded polyethylene sheath into cable after the aluminum polyethylene laminate vertical wrapped.

Application Stranded Loose Tube Ribbon Fiber Cable

The stranded loose tube ribbon fiber is suitable for Long distance and interoffice communication.
