PURPOSE: A heat resisting inline coupling is provided to offer heat resistance by additionally using a heat resisting sleeve within an inner coupling and to minimize insertion loss due to dislocation of an optical axis. CONSTITUTION: A cross section of a pair of POF(Plastic Optical Fiber) housings is arranged according to an optical axis in a heat resisting sleeve. The heat resisting sleeve comprises an external tube secluding heat and an internal tube which helps the arrangement of the POF housing. The external tube of the heat resisting sleeve is formed by silicon materials and the internal tube is formed by glass yarn. Inner couplings are combined in order to include the heat resisting sleeve. A cover(40) covers the inner coupling. |
