As shown in Figure 1, the metallic sheath 30 and the second energy-transmission optic fibre joint (not shown) that the biography that an embodiment of the utility model is described to have a temp monitoring function can optical cable 100 comprises energy-transmission optic fibre 10, the first energy-transmission optic fibre joint 20, separated each other by insulating medium.
Referring to Fig. 2 and Fig. 3, energy-transmission optic fibre 10 comprises fibre core 11 and covering 12, and the outside surface 12a of covering can pass through frosted and handle.At the described energy-transmission optic fibre 10 that passes optically-coupled end that can optical cable 100 of the utility model (promptly; At the clear glass end cap that will describe of back and the fiber section between the sheet metal) the outside surface of covering 12 light scattering pipe 13 is set; Light scattering pipe 13 can be processed through glass tube (for example quartz ampoule); Its refractive index greater than or be approximately equal to the refractive index of the covering 12 of optical fiber 10, its outside surface 13a handles through frosted.Light scattering pipe 13 can bond together through bonding agent 14 with the covering 12 of energy-transmission optic fibre 10.
Referring again to Fig. 1 and Fig. 2, the first embedded energy-transmission optic fibre joint 20 of an end of energy-transmission optic fibre 10 comprise metal tube 21, hermetically be fixed on clear glass end cap 22 in the end port of this metal tube 21, hermetically the sheet metal 23 in the other end port of fixing this metal tube, be fixed on sheet metal 23 in the face of on the surface of a side of clear glass end cap 22 and be parallel to grass tube 24 that metal tube 21 axis extend, near sheet metal 23 in the face of the surface of a side of clear glass end cap 22 and pass metal tube 21 tube walls and grass tube 24 tube walls water inlet pipe 25, near sheet metal 23 in the face of the surface of a side of clear glass end cap 22 and pass the rising pipe 26 of metal tube 21 tube walls; Closely around the heat radiator 27 of the outer wall setting of metal tube 21 and be arranged on the temperature sensor 28 in metal tube 21 outer walls.
A said end of energy-transmission optic fibre 10 passes sheet metal 23 and extends the end face of this end and 22 couplings of clear glass end cap in grass tube 24 inside along the axis of metal tube 21.In addition, as stated, closely be with light scattering pipe 13 in the part between clear glass end cap 22 and sheet metal 23 of this end of energy-transmission optic fibre 10.
