Structure of Central Tube Cable Optical fiber
The optical gel is filled in optical cables before they are completed and sheathed to pass waterproof tests and infiltration tests.
The buffer tube is a kind of the thermoplastic material and is made of polypropylene can nylon. The buffer tuber can be put in fiber cable loosely and protect optical fiber from interior stress and outer side pressure.
The strength member: two parallel phosphatized steel wire.
The water proofing material: filling compound
Armored layer: steel-plastics tape
The outer jacket uses black polyethylene and is easy to lay and transport. Description of Central Tube Ribbon Fiber Cable

We insert av single-mode or multi-mode into the loose tube made of high modulus polyester material and filled with water proof compounds. The external of loose tube is vertical wrapped double chromium-plated plastic steel tape. Water blocking material is added between the steel belt and loose tube to ensure the compact and vertical water blocking of the cable. Extruded polyethylene sheath into cable with two parallel wires placed on both sides.

Application of Central Tube Ribbon Fiber Cable

The central tube ribbon fiber cable is suitable for access to network and interoffice communication (GYDXTW)

Features
The cable has characteristics of low attenuation and low dispersion. The tube has good flexibility and anti- bending capacity. We use the high quality 12, 24 core belt of the pacific optical cable, so the installation is flexible. The unique steady surplus control technology make the cable has the excellent machinery and environment performance. The structure of optical fiber belt has high number of core. The steel wire armoring has good anti-pressure performance. Installation

Duct, Aerial, Directly burial
