탈피가 용이한 루즈튜브형 광케이블{Strip-easy optical cable of loose tube type}Strip-easy optical cable of loose tube type

본 발명은 탈피가 용이한 루즈튜브형 광케이블에 관한 것으로, 보다 상세하게는 광케이블의 분기시 광케이블의 피복층을 탈피가 보다 용이하게 이루어질 수 있도록하여 광케이블의 분기 공정을 단축시킬 수 있도록 된 탈피가 용이한 루즈튜브형 광케이블에 관한 것이다.The present invention relates to a loose tube type optical cable that can be easily stripped, and more particularly, a stripping easy loose that can shorten the branching process of the optical cable by making it easier to strip the coating layer of the optical cable when the optical cable is branched. It relates to a tubular optical cable.

일반적으로, 광케이블은 국내외적으로 랜(LAN, LOCAL AREA NETWORK) 보급확산, 양방향통신구현, 화상통화구현 등 다양한 통신서비스에 관련된 가입자 회로망의 보급추세에 따라 그 수요가 점차 증가되고 있다.In general, the demand for optical cables is gradually increasing due to the spread of subscriber networks related to various communication services such as local area network (LAN, local area network), bidirectional communication, and video call.

이러한 광케이블은 용도에 따라 다양한 종류가 있는데, 옥외의 선로에 설치되는 옥외용 케이블과 옥내에 설치되는 옥내용 케이블 및 옥외와 옥내사이에 설치되는 인입용 케이블로 크게 구분된다.There are various kinds of such optical cables according to the use, which are largely divided into outdoor cables installed in outdoor tracks, indoor cables installed indoors, and inlet cables installed between outdoor and indoor.

이러한 광케이블 중 옥내용 케이블은 빌딩과 같은 건축물의 내부 즉, 천장 혹은 바닥, 벽 등에 설치되는 케이블이고, 인입용 광케이블은 옥외용 케이블과 옥내용 케이블을 연결하는 케이블로서, 주로 근거리 지역간 접속을 위해 사용된다.Indoor cables among these optical cables are cables installed inside buildings such as buildings, such as ceilings, floors, walls, and the like, and incoming optical cables are cables for connecting outdoor cables and indoor cables, and are mainly used for short-distance connection. .

도 1은 종래의 루즈튜브형 광케이블을 나타내는 사시도이며, 도 2는 그 측단면도이다.1 is a perspective view showing a conventional loose tube optical cable, Figure 2 is a side cross-sectional view thereof.

이를 참조하면, 상기 광케이블(1)은 그 중심축에 다수의 광섬유소선(2)이 집합된 리본형상의 광섬유리본(4)이 위치되고, 이러한 광섬유리본(4)의 외표면에 그 광섬유리본(4)을 보호하기 위한 일정 두께의 플라스틱튜브인 루즈튜브(6)를 형성한다.Referring to this, in the optical cable 1, a ribbon-shaped optical fiber ribbon 4 in which a plurality of optical fiber wires 2 are assembled is located on a central axis thereof, and the optical fiber ribbon 4 is formed on an outer surface of the optical fiber ribbon 4. 4) to form a loose tube (6) of a plastic tube of a certain thickness to protect.

또한, 상기 루즈튜브(6)의 외주면에는 방수 및 상기 루즈튜브(6)를 보호하기 위한 차폐층(8)이 구성되는 바, 상기 차폐층(8)은 레핑테잎(Wrapping tape)형으로이루어진다.In addition, a shielding layer 8 for waterproofing and protecting the loose tube 6 is formed on an outer circumferential surface of the loose tube 6, and the shielding layer 8 is formed of a wrapping tape type.

한편, 상기 차폐층(8)의 외표면에는 보조인장선(10)과 그 내측 케이블을 보호하기 위한 플라스틱 케이블외피(12)를 형성하여 강도를 보강하게 된다.On the other hand, the outer surface of the shielding layer 8 to form a plastic cable jacket 12 for protecting the auxiliary tension line 10 and the inner cable to reinforce the strength.
