광선단 케이블 처리구조Light end cable processing structure

본 발명은 동도에서부터 전화국내로 인입되는 광선단 케이블의 처리구조에 관한 것으로, 특히 무접점 광선단 케이블의 사용으로 융착접속에 의한 손실을 방지하도록 한 광선단 케이블의 처리구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a processing structure for a light-end cable introduced into a telephone station from the same island, and more particularly to a processing structure for a light-end cable which prevents loss due to fusion splicing by using a contactless light-end cable.

일반적으로 광케이블이란 광파이버 케이블(Optical Fiber Cable)이라고도 불리는 광통신용 케이블을 말하며 석영 등을 소재로 한 가는 실같은 것을 몇백 가닥씩 묶어 케이블을 만든 것이며, 광파이버는 광대역, 저손실, 무유도, 경량 등의 특징을 갖고 있기 때문에 그 적용범위가 넓혀지고 있다.In general, an optical cable is an optical communication cable, also called an optical fiber cable, and is made of several hundred strands of thin thread made of quartz or the like. Because it has a wide range of applications.

한편 광케이블은 보통 일정 구간마다 광증폭기 및 함체를 접속 설치하는데 있어 그 접속방법을 종래는 전문 기술자의 수작업에 의존해 융착접속기(Fusin Splicer)라는 고가의 정밀장치를 이용해 현장내에서 광케이블 양단에 편단코드를 사용하여 융착 접속하는 방법을 사용하였다.On the other hand, optical cables usually connect and install optical amplifiers and enclosures at regular intervals.However, the method of connection is conventionally dependent on the manual work of a professional technician to use one-sided cords on both ends of the optical cable in the field using an expensive precision device called a fusion splicer. The method of fusion splicing was used.

이에 따라 접속시간이 길고 지속적인 외부 전력의 공급이 필요한데다 한번 이루어진 부분은 다시 접속할 수 없어 광케이블을 잇는데 최대의 걸림돌로 작용해 왔다.As a result, connection time is long and continuous external power supply is required, and once made part cannot be reconnected, which has acted as the biggest obstacle in connecting optical cables.

본 발명은 상기와 같은 사정을 감안하여 창안된 것으로, 광케이블 선단에 공지의 광케넥터를 부착한 광선단 케이블을 사용하되 접속손실을 방지함과 동시에 시공시 소요되었던 시간과 경제성을 향상시킬 수 있는 광선단 케이블의 처리구조를 제공함에 그 목적이 있다.The present invention was conceived in view of the above circumstances, but it is possible to use a light end cable having a known optical connector attached to the end of the optical cable, while preventing connection loss and at the same time improving the time and economic efficiency required during construction. Its purpose is to provide a cable handling structure.

상기의 목적을 달성하기 위한 본 발명의 구체적인 수단은, 단심 광섬유를 보호하기 위한 젤리 또는 우레탄 등의 충전제가 들어 있는 커버를 구비하고, 이 커버의 일단에 광케이블의 일단부를 고정, 지지하여 주는 실링테이프를 설치함과 동시에 그 타단에 공지의 광케이블의 커넥터가 연결된 광섬유 단심 보호튜브가 삽입 고정되는 전단면판을 고정 설치하고, 상기 전단면판에 상기 광케이블의 인장선을 압착단자를 이용하여 고정 지지토록하고, 상기 실링테이프에 광케이블을 지지하여 주는 후단면판을 설치하여 구성한 것을 특징으로 한다.Specific means of the present invention for achieving the above object is provided with a cover containing a filler such as jelly or urethane for protecting a single-core optical fiber, the sealing tape for fixing and supporting one end of the optical cable to one end of the cover At the same time, the other end is fixed to the front end plate is inserted into the optical fiber single-core protection tube connected to the connector of the known optical cable is fixed, and the tension line of the optical cable to the front end plate to the fixed support using a crimp terminal, Characterized in that the rear end plate for supporting the optical cable is installed on the sealing tape.
