Optical fiber box is also called optical fiber distribution frame, which is used to transmit digital and similar voice, video and data signals. Optical fiber box can be installed directly or desktop installation. Especially suitable for high speed optical fiber transmission. Also called optical fiber terminal box. Optical fiber terminal box is a cable terminal connector, a cable is his head, the other end is equivalent to a pigtail, split into a single fiber cable equipment, installed in the user cable terminal box on the wall, its function is to provide optical fiber and optical fiber welding, and welding and fiber pigtail the transfer of optical connector. And to provide mechanical protection and environmental protection for optical fiber and its components, and allow the appropriate inspection to maintain the highest standards of fiber management. Optical cable connection box is used to the overhead pipeline, buried, and well paved straight and branch connections. Actually there are too many fiber optic boxes and fiber management devices, they are hard to count the types, many manufacturers will make the fiber optic boxes according to their own design and they may give the fiber optic boxes different names and model numbers. Bigger size fiber optic boxes, the fiber patch panels, are usually 19 inch size. These fiber optic boxes can be wall mounted type or rack mounted type, and they have the tray inside the fiber box to hold and protect the fiber links. The fiber optic boxes panels can be pre-installed with various kinds of fiber optic adapters, these adapters are the interface via which the fiber box will connect the external devices. Smaller size fiber optic box, the terminal box, is also used for fiber optic distribution and organization. The fiber optic box are made of cold rolling steel and the surface of the box use the technique of dim blowing plastic. This type fiber optic box is typically installed with FC or ST adapters on the panel. This fiber terminal box could be installed on the wall or put in horizontal line.
