Position：Home > Outdoor ribbon cable
Description
The ribbon 4, 6, 8, 12 fibers，are positioned in a loose tube made of a high modulus plastic. The tube are filled with a water-resistant Ring compound.A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and Hers) are stranded around the strength member into a compact and circular cable core. An Aluminum Polyethylene Laminate (APL) is applied around the cable core，witch is filled the Ring compound to protect it from water ingress. Then，the cable is completed with a PE sheath.
Features
Good mechanical and temperature performance
High strength loose tube that is hydrolysis resistant
Special tube filling compound ensure a critical protection of fiber
Special designed compact structure is good at preventing loose tubes from shrinking
PE sheath protects cable from ultraviolet radiation
The following measures are taken to ensure the cable watertight:
1.Steel wire used as the central strength member
2.Loose tube filling compound
3.100% cable core filling
4.APL moisture barrier
