Fiber optic splice trays are designed to provide a location to store and to protect the fiber cables and the splices. Each tray provides space for mounting fiber splice protectors and excess fiber. It's divided into common splice tray, module integration and splitter tray. Optical fiber glass inside the fiber tray can be melt with any other strand optical fiber in the tray, thus different fiber optic cables can be melt connected directly via the tray. Optical cable fiber can also be melted with the fiber optic pigtail end, and via pigtail it can connect out to other fiber optic equipment.
