Description

GASKET AND OPTICAL CONNECTING BOX WITH THE SAME

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication line facility for signal transmission in an ultra-high speed network system, and more particularly, to an optical connection enclosure capable of connecting an optical cable connection and a connector.

Communication networks are a very important part of modern information society. Especially, as the network communication such as the Internet is developed and a large amount of data such as moving picture or voice is transmitted, the expansion of the communication network is urgently required.

In order to meet such a demand, the use of an optical cable instead of a conventional coaxial cable is rapidly increasing as a means for processing a large amount of information at a high speed. In recent years, the construction of FTTH (fiber to the home, fiber to the premises) network, which installs optical cables to each household, is proceeding at a government level to provide high-quality and high-speed services.

FIG. 1 is a schematic diagram of a conventional FTTH optical network.

In the FTTH optical fiber network, the optical cable is connected from the CO (10) to the subscriber home (20), unlike the conventional optical fiber cable which is connected only to the MDF. In such an FTTH optical cable network, an underground optical connection enclosure 30a, an aerial connection enclosure 30b, and an optical termination box (OTB) 30b are installed in the underground manhole, ) 40 and the like to the subscriber's home 20. The optical fiber cable 40 is connected to each subscriber's home 20 by a drop cable 60.

As described above, the existing FTTH optical fiber network has a structure in which the optical fiber cable is essentially connected to the subscriber's home (20) only when the optical fiber cable and the optical fiber cable have to pass through the optical fiber cable connection box. Recently, A connector-type connection box which can be connected to the optical jumper cords is used.

However, since the conventional connector-type connection case according to the related art adopts a structure in which a connector for connecting to the optical fiber of the inserted optical cable and distributing to the transmission device of the near optical subscriber is provided inside the main body, There is an inconvenience that an optical communication line must be opened after opening the cover coupled to the main body and there is a problem that a communication electronic device or an optical fiber provided inside the main body due to carelessness of the operator in opening the optical communication line is easily damaged .

Embodiments of the present invention are to provide a gasket which can easily be detached from a cable and an optical connection enclosure having the gasket.

In addition, the wings can be made of a pair of left and right through the incision line so that the cable can be opened upon insertion from the opening to the cable through hole.

Further, the vanes may be provided perpendicularly to the front and rear surfaces of the gasket body, respectively.

Further, the vanes may be provided horizontally on the upper surface of the gasket body.

Further, the gasket body may be provided with grooves along the longitudinal direction on the upper surface thereof.
