This kind of connection method of "opening a skylight" was used to be in the process of optical cable laying

encountered such as breaking the fiber and other sudden and abnormal conditions

then adopted rescue measures. While in recent years

the operation method of opening a skylight for skeleton type ribbon cable gradually developed a way of connection after skeleton type ribbon cable has been used widely

and is mainly used in optical communication laid in the high-rise buildings. The main advantage of opening a skylight for skeleton type ribbon cable is that you don’t have to break the entire cable to branch the fiber

but you can take out the required fiber ribbon through opening a skylight（other fiber bands are kept intact）. This paper mainly describes the advantages of the "open a skylight" connection method of the skeleton type ribbon cable in high-rise buildings

and introduces the operation method of "open a skylight" of the skeleton type cable.
