Fiber storing type optical fiber distribution box used for 19-inch cabinet

Abstract

The invention discloses a fiber storing type optical fiber distribution box used for a 19-inch cabinet. The optical fiber distribution box is structurally composed of an upper cover, a tray, a guide rail and a wiring trough. The tray is installed in the upper cover through the guide rail, a tail optical fiber body, with a certain length, of an optical fiber can be stored in the tray, the tail optical fiber body is wound on a winding post in the tray with four cores as a set, and meanwhile space for tail optical fiber body splicing and space for pre-terminated optical fiber winding are reserved in the tray. The optical fiber distribution box has the advantages that space in the optical fiber distribution box is fully used, the tail optical fiber body of the certain length can be stored on the premise that the bending radius of the optical fiber is met, and the tail optical fiber body can be used for being directly connected with another device; when the fiber storing type optical fiber distribution box is used, an optical fiber patch cord is not needed for being connected with another device, so that a movable connection point is reduced when the fiber storing type optical fiber distribution box is used, and loss of an optical fiber link is reduced; the optical fiber of the tray is movably connected with a parking space and is compatible with a standard optical fiber, and a standard optical fiber adapter can be installed.

Description

Technical field [0001] The invention relates to a fiber storage type optical fiber distribution box for a 19-inch cabinet, which belongs to the technical field of optical fiber connection devices. Background technique [0002] At present, with the increase of the fiber density in the cabinet, more and more cabinets need to install a large number of fiber storage units, so that the limited space in the cabinet is occupied, so that the space of the cabinet is small; for the fiber distribution box The following problems exist in the use of the optical fiber distribution box: 1. The optical fiber distribution box is only used for termination, and cannot store the excess length of the jumper, and cannot organize and manage the jumper; 2. The optical fiber storage box can only store the excess length of the jumper; 3. The use of boxes requires jumper connections, and each connection requires two active connection points, which increases the link loss. Summary of the invention [0003] ...
