Specification

Description

• The fibers dyed different colors, either of single-mode or multi-mode, are positioned in a loose tube. 
• The tube is made of high Young’s modulus plastic and filled with water-resistant filling compound.
• The tube is wrapped longitudinally with a layer of PSP (Plastic-Steel-Plastic) laminated tape.
• Between PSP and loose tube, water-blocking material is applied to keep cable compact and watertight.
• Two parallel steel wires are placed at the two sides of the PSP tape.
• The cable is completed with polyethylene (PE) sheath.

Features

• Compact structure and lightness, flexible and good bend-resistance performance.
• Loose tube construction provides environmental protection.

Applications

• Used in local and interoffice communication wiring, CATV, computer transmission system.
• Installed in ducts, underground conduit or aerial/lashed.
