Definitions

• the present invention relates to an optical cable closure and a method of using the same.
• an optical cable closure comprises a cover and a housing which are separate from each other. During the operation, the cover and the housing must be disconnected. As a result, the operation becomes very complicated.
• the adapter and the splice tray are positioned in two independent chambers. Consequently, the two independent chambers both need to be opened when an operator carries out a fiber managing operation or a fiber jumpering operation. Accordingly, it is rather inconvenient in use.
• the conventional optical cable closure is bulky in size because the assembling configuration of the adapter is not desirable.
• the present invention has been made to overcome or alleviate at least one aspect of the above mentioned disadvantages. Accordingly, it is an object of the present invention to provide an optical cable closure which facilitates ease usage of itself.
• an optical cable closure comprising: a splice tray; a housing for accommodating the splice tray therein; and a cover for opening and closing the housing, wherein one side of the cover is rotatably connected to one side of the housing; and one side of the splice tray is rotatably connected to the other side of the housing.
• the splice tray and the cover both can be rotated and opened relative to the housing, an operator can easily carry out various operations on the front surface and the back surface of the splice tray.
• Fig.l is a perspective schematic view of an optical cable closure according to an embodiment of the present invention, showing the cover and the splice tray of the optical cable closure both are opened;
