Abstract:
An optical fiber cable including a central strength member extending along a longitudinal axis of the optical fiber cable and a plurality of buffer tubes that are wound around the central strength member. Each of the plurality of buffer tubes includes a first material having a modulus of elasticity of at most 600 MPa at room temperature and a peak heat release rate (PHRR) of at most 300 kW/m2 as measured according to ASTM E1354. A cable jacket is disposed circumferentially around the plurality of buffer tubes and extends along the longitudinal axis.
