Telecommunications cables include elements made of thermoplastic material which is reinforced by discontinuous reinforcement fibers made of materials such as glass. The reinforcement fibers each have a length of less than 0.2 cm and are incorporated in the thermoplastic material to reduce the coefficient of thermal expansion of the thermoplastic material. Tubes reinforced by the short reinforcement fibers have good flexibility. Such tubes are used as cable jackets and as buffer tubes carrying telecommunications elements in cables. The cables may also have strength members coated with a plastic material incorporating the reinforcement fibers.
