This type of cable generally is used between urbans over long distances and is installed in the infrastructure networks and directly into the 5011. The central strength member consists of Fiber Reinforced Plastic(FRP) which may be coated with polyethylen . coating for adaptability of tubes and FRP. The filling compound fill all interestices between tubes in cable core for protection against water penetration. This cable has equipped with a protective corrugated steel tape. This layer protect cable against ouside stresses and rodent. For more protecting against pulling during installation and operation I the aramid yarns may be used in cable structure.
