An optical fiber code holding structure, includes: an optical adapter and an optical fiber code holding member. An optical connector of an optical fiber is connected to an optical adapter. The optical connector is attached to an end of an optical fiber code of the optical fiber. The optical fiber code holding member has a light shielding device shielding lights emitted from the optical adapter and a holding device holding the optical fiber code.

OPTICAL FIBER CODE HOLDING STRUCTURE IN WHICH THE NUMBER OF THE PARTS FOR THE FUNCTION OF PROTECTING THE LIGHT FROM BEING DIRECTLY VIEWED AND THE FUNCTION OF HOLDING THE OPTICAL FIBER CODE IS REDUCED AND THE CONNECTING WORK OF AN OPTICAL CONNECTOR IS EASILY PERFORMED

An electric system has exothermic components housed in a case; the case is formed with ventilation holes, and a fan forcibly evacuates the hot air from the inner space through the ventilation holes for removing heat from the exothermic components; foamable pain is spread on the surface near the ventilation hole, and a fuse element is exposed to the air passage; when a fire breaks out inside the case, the paint foams for closing the ventilation hole, and the fuse element stops the fans, whereby the fire is extinguished without being spread to the outside the case.

Electric system with safety device against spread of fire occurred inside casing
