OPTICAL CABLE CFOA-SM-DDR-S 24F G-652D (PFV) LSZH
Dielectric optical cable recommended for external installations in ducts or directly buried.Construction made gel-filled loose tubes. Tubes assembled around the central element, the core of the cable is protected against moisture by hydro expandable materials and an inner jacket of thermoplastic material. Fiberglass yarns are used as additional protection against rodents. The assembly is protected by an outer jacket of thermoplastic weather resistant material.

Construction
Description
Totally dielectric cables with singlemode optical fibers covered with acrylate. Fibers are protected by loose tube buffers stranded around the dielectric central member. The cable core may be gel-filled or protected with swellabe materials to avoid water penetration. Core is covered with a polyethylene inner jacket. Around the inner jacket, there is a fiberglass layer to improve resistance against rodents. The cable is covered with a black polyethylene or LZSH outer jacket.
Application
| Installation Environment | Outdoor or Indoor/Outdoor (LSZH) |
| Operation Environment | In ducts or directly buried. Recommended for installations in places with possibility of rodents attack (Rattus norvegicus or Rattus rattus). |

Central Member
Dielectric-material element located in the center of the core cable to prevent the efforts of the cable tension. As central member, it is applied a bar of plastic material reinforced by FRP (Fiber Reinforced Plastic) fiberglass.
Core
The loose tubes are stranded around of central member to form the cable core. The core must be protected with gel or water blocking material to prevent water intrusion. If necessary, filler rods may be applied to maintain a cylindrical core.
