Mixed-mode temperature measurement communication phase conductor and temperature measurement communication system

Disclosed are a mixed-mode temperature measurement communication phase conductor and a temperature measurement communication system. The mixed-mode temperature measurement communication phase conductor includes: a stainless steel sleeve optical fibre unit and a support wire stranded together with the stainless steel sleeve optical fibre unit, and an aluminium wire is stranded outside the stainless steel sleeve optical fibre unit and the support wire. The stainless steel sleeve optical fibre unit includes: a plurality of single-mode optical fibres and at least one multi-mode optical fibre, and the optical fibres in the stainless steel sleeve optical fibre unit are stranded with one another. By providing single-mode optical fibres for communication, and by measuring the temperature via a multi-mode optical fibre, the present invention realizes that whole-course temperature measurement can be performed on a conductor.
