Optical fiber distribution frame

Abstract

The invention provides an optical fiber distribution frame which comprises a distribution frame body, a front door, a side plate, a rear door, top fixing holes, a distribution box rack, a top plate, a bottom plate and bottom fixing holes, and further comprises pulleys, a side vertical wire duct, a coiling ring, an intermediate vertical wire duct and an annular wire duct. The front door, the side plate and the rear door are fixed to the front, the side and the back of the distribution frame body respectively. The top fixing holes are arranged in the top plate. The bottom fixing holes are arranged in the bottom plate. The distribution box rack is connected with the top and the bottom of the distribution frame body through the top fixing holes and the bottom fixing holes respectively. The pulleys are fixed to the four corners of the bottom plate. The side vertical wire duct is fixed to the side of the distribution frame body. The intermediate vertical wire duct is fixed to the center of the distribution box rack. The annular wire duct is fixed to the bottom plate. The optical fiber distribution frame is simple in structure, and can easily achieve connection, distribution and scheduling of an optical fiber line.

Description

technical field [0001] The invention relates to the technical field of optical communication equipment, in particular to an optical fiber distribution frame. Background technique [0002] Optical fiber distribution frame is an important supporting equipment in the optical transmission system. It is mainly used for optical fiber fusion at the end of the optical cable, installation of optical connectors, adjustment of optical paths, storage of redundant pigtails, and protection of optical cables. The safe operation and flexible use of communication networks play an important role. Now optical communication has been widely used in long-distance trunk lines and local network transmission, and higher requirements have been put forward for its capacity, function and structure. The existing distribution frames have certain shortcomings and deficiencies, mainly in the following aspects: : The frame structure of the distribution frame has closed type, semi-closed type and open type,...

Problems solved by technology

Now optical communication has been widely used in long-distance trunk lines and local network transmission, and higher requirements have been put forward for its capacity, function and structure. The existing distribution frames have certain shortcomings and deficiencies, mainly in the following aspects: : The frame structure of the distribution frame has closed type, semi-closed type and open type, each has advantages and disadvantages, can not achieve dustproof, good heat dissipation effect, and can also be easy to install and use; in the process of use, because the optical fiber line cannot be bent at will Transformation results in unreasonable use of space and waste of space; these not only make it difficult to install and maintain distribution cables or connecting cables, but also bring inconvenience to the expansion and upgrading of later equipment
