The Tele-fonika Z-XOTKtsd 12J cable features a multi-tube construction, where loose tubes are wrapped around a central Fiber Reinforced Polymer (FRP) strength member made of glass fiber. In this specific case, only one tube is filled with 12 optical fibers, hence the designation 1x12. The remaining tubes serve as cable fillers.
The fiber optic cable includes a mini-tube with a diameter of 1.8 mm. Compared to the traditional 2.4 mm tube, the outer diameter of the cable has been reduced, resulting in favorable parameters such as a decreased minimum bending radius (reduced by 30%) and cable mass. While the cable is half as strong in tensile strength as the version with a traditional tube, the nearly doubled reduction in mass balances this out. An additional advantage of the reduced mass is simplified logistics, particularly in the ease of laying or blowing the lightweight cable.
A distinguishing feature of this type of cable is its relatively small diameter for a multi-tube cable, which may positively impact reducing the costs associated with telecommunication duct occupancy, for example, for Orange.
