The present invention relates to an optical fiber protective support plate for the connection point protection and the rearranging of the optical fiber when the optical fiber connection in the optical distribution box, optical terminal box and the like.

In general, an optical communication system composed of optical cables and electronic devices is widely used in the communication industry that delivers a large amount of voice and non-voice data signals from telephone stations to optical subscribers.

The optical cables forming the optical communication lines are interconnected by various kinds of related optical connection materials such as optical connection enclosures, optical distribution boxes or optical terminal boxes or can be branched to the optical subscriber transmission device. Here, the optical cable includes a plurality of optical fibers consisting of a core and a cladding layer, and various types thereof, but in the example of a loose tube type optical cable, a loose tube having a single or double coated optical fiber around a center tensile line Is wound in a circular shape with an outer winding tape and aluminum tape, and surrounded by a PE coated shell.

The optical connecting materials are provided in various ways in structure and shape, and are provided with an optical fiber protective support plate for optical fiber connection point protection and optical fiber filtering process. That is, the optical cable is generally introduced into the optical connection material, and then protected by protecting the optical fiber in the optical cable with a protective tube, and after the protective tube is filtered to a predetermined curvature, the optical fiber exposed at the end of the protective tube is optically connected to the optical fiber connector. Branching is made by connecting with an optical cable or by an optical jumper cord. At this time, support for optical fiber protection? The optical fiber exposed to the end of the protective tube is filtered to a predetermined curvature and the optical fiber connector is fixed to protect the optical connection point due to external impact. Here, the optical fiber splicer has various types, and mainly, a fusion splicer or a mechanical splice is used.

1 is a perspective view showing one example of such a conventional optical fiber protective support plate.
