Contractile possible conservation element (101), the element which extending is present long

摘要

This invention regards the device and method in order to shrink fit contractile possible protective element (101) on the optical waveguide (100) by supplying heat. According to this method, the heat radiation line is discharged, the said heat radiation line is made to reflect, the said heat radiation line is made to focus with respect to the focus territory where the aforementioned protective element (101) is kept. In addition this device making the radiation reflect which from heat element (10) in order to discharge the heat radiation line and the said heat element (10) is discharged, the reflector (30) in order to make focus with respect to the aforementioned focus territory and, has had with the holder (20) which keeps protective element (101) inside the aforementioned focus territory.
