Abstract

The present invention relates to an optical splitter module for FTTH, which is easy to install in various environments, and more particularly to a novel concept that not only an optical splitter module can be easily installed at various places, but also a separate optical terminal box is not used.
Conventionally, a light box having a built-in optical splitter can be installed only in a single place, so that it can not be easily installed without being limited to the place where the installation is made. The size of the optical splitter is small while the size of the optical box itself is larger than necessary Which is not only very expensive but also causes a problem of enlargement.
In order to solve such a problem, the present invention is characterized in that any one of a hanging hanger, a holder for a wall surface and a fixed holder for electric pole is mounted on an optical splitter module modularized into a compact size by incorporating only an optical splitter, It is characterized by the ability to easily install the module without being restricted by the installation site.

There are various types of fiber optic cable such as loose tube type and ribbon type. Especially, the loose tube type optical cable used in the subscriber net and the distribution point requiring high-capacity high-speed communication is composed of a center tension line using zinc stiffness or FRP, A tube-shaped inner sheath and an outer sheath which are covered with a black polyethylene using a jelly compound and a loose tube made of thermoplastic plastic.

On the other hand, as a subscriber termination device required to perform a connection and distribution function between an external optical line and a subscriber transmission module, an optical line terminal is installed on an inner wall or an inner wall of a building of an optical subscriber to form an optical subscriber cable network.

As a prior art related to the above-mentioned optical fiber bundle, "Patent Registration No. 962257, name / optical fiber bundle" is published.

The optical fiber connector of the prior art has a case in which a cover that can be opened and closed is hinge-connected, a connector access portion provided at one side of the case to allow an external optical connector to enter and exit the inside of the case, And a splitter provided on an upper surface of the tray.

Such a photovoltaic box is required to be installed at various places such as a pole, a sidewall, a building wall, and a terminal box according to the field conditions. The conventional photovoltaic box can be installed only in a single place, There is no problem.

In addition, the size of the optical splitter, which is built in the conventional optical fiber box and performs the most important function, is small, but the standard of the optical fiber bundle itself is unnecessarily large, which causes not only a high price but also a large size.

In order to solve the above-mentioned problems, the present invention provides an optical splitter module having a compact size by incorporating only an optical splitter and mounting a hanging hanger, a wall holder, and a fixed holder for electric pole, Be sure to install the splitter module so that it can be easily installed without being restricted by the installation location.

According to the present invention, it is possible to easily install and assemble the optical splitter module in various places without being restricted by installation sites (electric poles, tie bars, building walls, terminal boxes, etc.).

In addition, it is possible to greatly reduce the manufacturing cost through modularization of the optical splitter without using a separate optical terminal box, and also to realize the miniaturization of the optical splitter module, thereby improving the easiness of loading and transportation.
