Description

Modular type optical fiber distribution apparatus with optical fiber storage

The present invention relates to a modular optical distribution panel with a built-in dressing board, in particular, a light distribution board and a board mounting board, etc., and a device having a structure that can facilitate the arrangement of optical incoming cables and jumper cords.

In general, an optical fiber distribution (OFD) is used to perform a function of connecting and distributing an incoming optical fiber and an outgoing optical fiber so as to freely change and register an optical fiber to establish an optical transmission network.

The optical distribution panel is a distribution enclosure in which an adapter mounting plate and an optical fiber connecting plate are installed to interconnect and switch the optical distribution panel, the optical station device, and the optical relay device. It accepts the inlet and outlet jumper cords and stores them in an optical fiber storage (OFS) that functions to organize and protect the optical cables.

Figure 20 shows the appearance according to the capacity of the conventional optical distribution panel, the capacity is usually 12C, 24C, 48C, 72C, 96C, 144C optical distribution panel (OFD) has to be installed a separate optical distribution panel for additional expansion.

FIG. 21 shows the internal structure of (a) in FIG. 20, which is composed of an upper edge trimming arrangement, an interrupting portion adaptor portion, and a lower end portion optical core excitation portion.

As shown in the drawing, an optical cable assembly is easy as an advantage of a conventional integrated device in which an optical adapter installation position, an optical jump code (OJC), and a dressing arrangement are integrated.

However, such an integrated optical distribution panel has a possibility of optical transmission loss due to bending when the optical jumper code (OJC) is arranged due to lack of space in the optical jumper code (OJC), and an artificial obstacle due to the intensive arrangement of the optical adapter. There is a concern that it may cause, there is a disadvantage of insufficient space utilization as an OFD additional facility when the optical cable is expanded, and additionally, an optical distribution board having a quantified cable connection number must be purchased when the optical cable is expanded.

The purpose of the present invention for solving the above problems is to solve the space problem resulting from the structure that the optical jumper cord (OJC) dressing box, the optical adapter installation portion, the slide panel portion, etc. are integrated, and further expansion of the optical cable The present invention provides an optical distribution box that can be easily installed by using a conventional capacity without purchasing a separate optical distribution box.

The purpose of the present invention as described above is to overcome the inefficient space utilization part of the existing optical distribution board (OFD) only by the expansion of the optical module module (Module) elastic additional expansion (36 modules per rack, can accommodate 12C per module) and At the same time, it solves the obstacles in the management of the optical adapter and causes the optical jumper cord (OJC) rearranging part in the narrow space of the existing optical distribution board (OFD) through the cable hole and the cable guide facility. Modular optical central distribution box formed with integrated trimming panel and optical distribution panel to solve the optical cable transmission loss and aesthetic problems that could be possible, and to be easy to maintain and maintain by rotating slide type (MOFD: Main Optical Fiber Distribution frame) ) By providing the device.
