광섬유케이블 종단 조립용 보호 튜브{protection tube for engaging leading end of optical fiber cable} Protection tube for engaging leading end of optical fiber cable

본 발명은 광섬유케이블 종단 조립용 보호 튜브에 관한 것으로서, 다심 광섬유케이블로부터 접속을 위해 노출되게 분리된 광섬유요소를 보호하기 위한 광섬유케이블 종단 조립용 보호 튜브에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective tube for optical fiber cable termination assembly, and to a protective tube for optical fiber cable termination assembly for protecting an optical fiber element exposed to be exposed for connection from a multicore optical fiber cable.

최근 초고속 광통신망의 시설 확충에 따라 광통신 선로가 옥내까지 설치되고 있다.Recently, with the expansion of the high speed optical communication network, optical communication lines have been installed indoors.

광섬유케이블은 용도에 따라 크게 옥외에 설치되는 옥외 광케이블과, 옥내에 설치되는 옥내 케이블 및 옥외와 옥내 사이에 설치되는 인입용 케이블로 구분된다. 인입용 케이블은 옥외용 케이블과 옥내용 케이블을 연결하기 위한 것으로서, 근거리 지역간 접속을 위해 사용된다. 일반적으로 인입용 케이블은 공중에 설치되는 케이블로부터 분기부를 통해 분기된 개별 광섬유요소를 옥내용 케이블과 커넥터를 통해 연결시키는 구조로 시설된다.Optical fiber cables are classified into outdoor optical cables, which are installed outdoors, indoor cables, which are installed indoors, and cable for entry, which is installed between the outdoors and indoors. The entry cable is used to connect the outdoor cable and the indoor cable, and is used for the connection between short distances. In general, the incoming cable is installed in a structure that connects the individual optical fiber elements branched through the branch from the cable installed in the air through the indoor cable and the connector.

그런데, 옥외용 광섬유 케이블로부터 피복을 탈피하여 분리된 광섬유요소를 옥내 또는 별도의 접속함까지 연장시키기 위해서는 연장 길이가 길게는 10m이상 요 구되기 때문에 노출된 광섬유 요소를 보호할 필요가 있다.However, in order to extend the separated optical fiber element from the outdoor optical fiber cable to the indoor or separate junction box, it is necessary to protect the exposed optical fiber element because the extension length is required to be 10 m or more.

종래의 광섬유 케이블 종단용 보호튜브의 경우 단순히 일반 광케이블의 피복용 소재로 사용하는 폴리에틸렌, 폴리우레탄 등으로만 형성하여 10m 정도로 길게 노출되게 연장된 광섬유요소를 작업자가 수작업으로 삽입시키기에는 마찰계수가 높아 작업현장에서 보호 튜브 내로 개별 광섬유를 원활하게 삽입시키기가 어려운 문제점이 있다.In the case of the conventional protective tube for optical fiber cable termination, the coefficient of friction is too high for the operator to manually insert the optical fiber element exposed to a length of about 10 m by forming only polyethylene, polyurethane, etc., which is used as a coating material for general optical cable. There is a problem in that it is difficult to smoothly insert individual optical fibers into the protective tube at the workplace.

본 발명은 상기와 같은 문제점을 개선하기 위하여 창안된 것으로서, 광케이블 종단으로부터 탈피되어 분리된 개별 광섬유요소의 진입가능 길이를 증대시킬 수 있도록 낮은 마찰계수를 갖는 광섬유케이블 종단 조립용 보호 튜브를 제공하는데 그 목적이 있다. The present invention has been made to solve the above problems, and provides a protective tube for assembling optical fiber cable ends having a low coefficient of friction so as to increase the accessible length of the individual optical fiber elements separated and separated from the optical cable ends. There is a purpose.
