The invention discloses a temperature measurement soft fire resistant transmission signal cable which comprises a cable core which is formed by twisting three insulating wire cores and a fiber unit. The gap of the cable core is filled with glass fibers. A flame retardant fireproof layer is extruded outside the cable core. A metal conductive tube is extruded outside the flame retardant fireproof layer. An outer sheath is arranged outside the metal conductive tube. A temperature monitoring wire core is also arranged in the outer sheath and can monitor the temperature change of the cable in use, and external monitoring equipment is connected through a monitoring cable to carry out alarming.
