Ribbon optical cables are used for duct, direct buried, and aerial installations. These cables have a specific design of water block yarn that helps eliminate the steps associated with standard gel-filled cables.
This is a stranded loose tube cable with optical fibres placed inside robust buffer tubes stranded around a fibre-reinforced plastic (FRP) central strength member.
In addition to optical fibres, the buffer tubes contain water-blocking gel and the cable core is surrounded with a water-swellable tape to prevent water ingress in the interstices of the cable core. Glass roving yarns are distributed over the inner sheath, and a thermoplastic jacket provides the cable with both mechanical and environmental protection.
