The present invention relates to an optical communication distribution training system, and more particularly, to a campus cabling distribution rack structure that can properly evaluate the actual performance of the trainees in an environment similar to that of an actual optical communication system.

Recently, optical communication technology has been in the spotlight as a communication system capable of transmitting a large amount of information at high speed. In particular, the FTTH (fiber to the home) network, a broadcasting / communication convergence service, provides an optical cable with a subscriber line from the telephone company to each home and transmits the telephone, fax, data communication, and TV images through one optical cable. It is widely used as a method of constructing a track.

Therefore, in accordance with the spread of the optical communication system, it is required to cultivate optical communication professionals for designing and constructing the optical communication system, and in order to cultivate optical communication professionals according to these demands and to evaluate according to appropriate criteria, optical communication similar to the actual optical communication network environment. Distribution training systems are being used.

1 shows a schematic configuration diagram of a conventional optical communication distribution training system.

In general, an optical communication distribution training system includes a data transmission unit for providing an optical signal for training, an optical distribution unit configured to distribute two lines connected to the data transmission unit through an input line, an indoor network unit connected to one line, and the other. It includes an outdoor distribution network connected to one line.

The indoor network unit includes a model structure divided into a plurality of subscriber indoor booths, and includes an internal terminal box provided on one side of the booth and a plurality of output terminal boxes provided on inner walls of the plurality of subscriber indoor booths, respectively.

In addition, the outdoor distribution panel includes a rack structure including two racks on each side and one cable support rack therebetween, and the two main racks on both sides each have a main distribution frame material and a training sub-wiring unit. The material is mounted.

The practitioner can practice the optical communication distribution work such as the data cabling of the data transmitter and the optical distribution board, the multimedia cabling of the indoor network, and the campus cabling of the outdoor distribution board. Work ability can be evaluated.

However, since the conventional optical communication distribution training system is a model structure that virtually embodies a real environment, the learning effect or the reliability of the evaluation may be greatly problematic in an iterative training and evaluation process.

In particular, in the case of outdoor distribution halves, UTP (4P), UTP (25P), telephone cables, single-mode and multi-mode optical cables from the main wiring section to the sub-wiring sections corresponding to other outdoor structures (e.g., different buildings of the apartment). Practice / evaluation work is required to carry out track work on the track and to measure the loss values for various tracks along with actual work proficiency (line treatment, connection status, etc.). Here, the measured loss value is determined by the length of the cable. Since this model structure provides only one wiring condition determined by the predetermined rack structure, it is difficult to make an appropriate measurement evaluation considering various changing environments. . Even since the measurement results are likely to be leaked by the preceding practitioners in various evaluation processes, the reliability of the practical evaluation may be greatly degraded.

The present invention is to solve the above problems of the prior art, an object of the present invention is to provide a new distribution rack structure that can be changed to various practice conditions in order to increase the reliability of campus cabling practice and evaluation in the optical communication distribution practice system. have.
