Temperature — Multi-pair PVC 24 AWG telephone cable typically has an attenuation of
approximately 8–10 dB/100 m at 20°C (68°F). The attenuation of PVC insulated cable varies with
temperature. At temperatures greater than 40°C (104°F), use plenum-rated cable to ensure that
attenuation remains within specification.
