Description

리본 튜브형 광케이블{Ribbon-tubed optical cable}Ribbon tube type optical cable {Ribbon-tubed optical cable}

본 발명은 광케이블에 관한 것으로서, 보다 상세하게는 구성을 단순화함과 아울러 항온, 인장력 등을 향상시킨 리본 튜브형 광케이블에 관한 것이다.The present invention relates to an optical cable, and more particularly, to a ribbon tube type optical cable that simplifies the configuration and improves constant temperature, tensile force, and the like.

일반적으로, 광섬유는 일정한 속도 및 방향으로 회전되는 석영관 내부에 원료 가스인 SiCl4, POCl3, Fluorine, BCl3, GeCl4등을 적당한 비율로 공급함과 아울러 석영관을 좌우 이동 가능한 버너로 가열하는 화학 기상 증착법등에 의해 모재를 제작하게 된다.In general, an optical fiber supplies a raw material of SiCl 4 , POCl 3 , Fluorine, BCl 3 , GeCl 4, etc. in an appropriate ratio inside a quartz tube that is rotated at a constant speed and direction, and heats the quartz tube with a burner capable of moving left and right. The base metal is produced by chemical vapor deposition.

모재가 제작되면 이를 가열함과 아울러 소정 인장력을 가해 미세한 직경의광섬유를 방사 공정을 통해 제작하게 되는 바, 상기한 광섬유는 기계적으로 매우 약하기 때문에, 외부에 피복을 하여 보호하게 된다.When the base material is manufactured, it is heated and a predetermined tensile force is applied to produce a fine diameter optical fiber through a spinning process. Since the optical fiber is very weak mechanically, it is protected by covering the outside.

이는 도 2에 도시된 바와 같이 광섬유(50)를 보호하기 위해 그 외곽을 둘러싼 플라스틱 재질의 루즈 튜브(51)와, 상기한 루즈 튜브(51)를 보호함과 아울러 방수를 위해 둘러싼 래핑 테이프(wrapping tape)(52)와, 상기한 래핑 테이프(52)의 외곽을 커버하도록 둘러싼 재킷(53)으로 광케이블(54)이 구성되어 있다.As shown in FIG. 2, it is wrapped with a plastic wrap tube 51 wrapped around its outer edge to protect the optical fiber 50 and the wrap tube 51 for waterproof while protecting the loose tube 51. The optical cable 54 is comprised by the tape 52 and the jacket 53 enclosed so that the outer edge of the wrapping tape 52 may be covered.

특히, 상기한 재킷(53)에는 광케이블(54) 전체를 지지 및 인장하도록 인장선 (55)이 삽입되어 전체 길이만큼 연장되어 있고, 광섬유(50)와 루즈 튜브(51)의 사이에는 충진재(56)가 충진되어 있게 된다.In particular, the jacket 53 has a tensile line 55 is inserted to extend and support the entire length of the optical cable 54 to support and tension the entire optical cable 54, the filler 56 between the optical fiber 50 and the loose tube (51). ) Is filled.

즉, 광섬유(50) 보호 및 방수를 위해 플라스틱 재질인 루즈 튜브(51)와 래핑 테이프(52)가 둘러싸여져 있고, 광케이블 전체 보호 및 지지를 위해 보다 강한 재질의 재킷(54)과 인장선(55)이 설치되어 있는 것이다.That is, it is surrounded by a loose tube 51 and a wrapping tape 52 made of plastic for protecting and waterproofing the optical fiber 50, and a jacket 54 and a tensile line 55 of a stronger material for protecting and supporting the entire optical cable. ) Is installed.

상기한 루즈 튜브(51)는 항온, 충격 흡수, 압축 특성 만족을 위해 0.75mm 두께의 플라스틱등으로 제작된다.The loose tube 51 is made of 0.75 mm thick plastic for constant temperature, shock absorption, and compression characteristics.

그러나, 상기한 바와 같이 광섬유를 보호하기 위하여 루즈 튜브, 래핑 테이프, 재킷, 인장선을 사용하게 되면, 광 케이블의 구성이 복잡하게 됨과 아울러 상기한 각각의 부품들을 삽입 및 제작하는 공정이 매우 복잡하게 되고, 이로 인해 작업 능률이 저하되는 문제점이 있다.However, when the loose tube, the wrapping tape, the jacket and the tension line are used to protect the optical fiber as described above, the configuration of the optical cable is complicated and the process of inserting and manufacturing the respective components is very complicated. In this case, there is a problem that the work efficiency is lowered.

또한, 루즈 튜브 및 재킷을 플라스틱으로 제작하기 때문에, 외부 충격, 압축력 등에 의해 쉽게 파괴되는 문제점이 있다.In addition, since the loose tube and the jacket are made of plastic, there is a problem of being easily broken by external impact, compression force, and the like.

따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 광케이블의 내충격성, 항온 성능 및 압축 특성을 향상시킴과 아울러 구성을 단순화하여 작업 능률을 향상시킬 수 있는 루즈 튜브형 광케이블을 제공함에 있다.Accordingly, an object of the present invention is to solve the above problems, to improve the impact resistance, constant temperature performance and compression characteristics of the optical cable, and to provide a loose tube type optical cable that can simplify the configuration to improve the work efficiency.

1: 스틸 튜브50: 광섬유1: steel tube 50: optical fiber

53: 재킷56: 충진재53: jacket 56: filler

상기한 목적을 실현하기 위하여 본 고안은 광섬유를 재킷 내부에 내장한 리본 튜브형 광케이블에 있어서,In order to achieve the above object, the present invention provides a ribbon tube optical cable having an optical fiber embedded in a jacket.

상기한 광섬유와 재킷 사이에 위치되어 광섬유를 둘러싸도록 금속 재질로 압출 성형된 스틸 튜브를 포함함을 특징으로 한다.Located between the optical fiber and the jacket characterized in that it comprises a steel tube extruded from a metal material to surround the optical fiber.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명한다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명의 실시예에 따른 루즈 튜브형 광케이블을 도시한 단면도로서, 광섬유(50)가 스틸 튜브(1)와 함께 압출되면서 스틸 튜브(1)의 중심에 위치되어 있고, 스틸 튜브(1)의 외부에 재킷(53)이 둘러 쌓여져 있다.1 is a cross-sectional view showing a loose tube optical fiber according to an embodiment of the present invention, the optical fiber 50 is located in the center of the steel tube (1) while being extruded with the steel tube (1), the steel tube (1) The jacket 53 is enclosed outside.

상기한 스틸 튜브(1)의 두께는 대략 0.3mm 정도로 압출되는 바, 상기한 두께는 스틸 튜브(1)의 강도를 유지하면서 최대한 무게를 가볍게 하기 위한 것이다.The thickness of the steel tube 1 is extruded to about 0.3mm bar, the thickness is to lighten the weight as much as possible while maintaining the strength of the steel tube (1).

또한, 상기한 스틸 튜브(1)와 광섬유(50)와의 사이에는 충진재(56)가 개재되어 있게 되는 바, 실질적으로 광케이블의 구성이 광섬유(50), 스틸 튜브(1), 재킷(53)만으로 이루어짐으로써, 그 구성이 단순하게 되고, 이로 인해 제작이 용이하게 된다.In addition, the filler 56 is interposed between the steel tube 1 and the optical fiber 50, and substantially the configuration of the optical cable consists of only the optical fiber 50, the steel tube 1, and the jacket 53. By doing so, the configuration becomes simple, which makes the production easy.

상기한 스틸 튜브(1)는 두께가 얇게 압출 성형되어 소정량 이상의 굴곡이 가능하고, 중량도 비교적 적게 나가게 되는 바, 상기한 광섬유(50)와 함께 광케이블을 형성할 때 케이블 자체의 중량이 너무 증가되지 않게 된다.Since the steel tube 1 is extruded to have a thin thickness, it is possible to bend a predetermined amount or more, and the weight is relatively low, so that the weight of the cable itself increases too much when the optical cable is formed together with the optical fiber 50. Will not be.

상기한 바와 같은 본 발명의 작용 효과를 설명하면 소정의 금속관 압출 장치에 광섬유(50)를 삽입시킨 후, 상기한 광섬유(50)와 함께 금속관(스틸 튜브(1))을 압출 성형하게 된다.When explaining the operation and effect of the present invention as described above, after inserting the optical fiber 50 in a predetermined metal tube extrusion apparatus, the metal tube (steel tube 1) together with the optical fiber 50 is extruded.

스틸 튜브(1)를 압출하게 되면, 상기한 광섬유(50)가 스틸 튜브(1)의 중심부에 위치된 상태에서 광케이블이 제작되는 바, 상기한 스틸 튜브(1)는 종래의 루즈 튜브(51)에 비해 강성이 매우 강하기 때문에, 별도의 인장선(55)이 필요치 않게 된다.When the steel tube 1 is extruded, an optical cable is manufactured while the optical fiber 50 is located at the center of the steel tube 1, and the steel tube 1 is a conventional loose tube 51. Since the rigidity is very strong compared to that, a separate tension line 55 is not necessary.

즉, 종래에는 광케이블의 강성 유지를 위해 별도의 인장선(55)을 광케이블에 삽입하였지만, 본 발명에서는 루즈 튜브(51)의 역할을 하는 스틸 튜브(1) 자체가 금속 튜브이기 때문에 인장선의 역할을 하게 되는 것이다.That is, although a conventional tension line 55 is inserted into the optical cable in order to maintain the rigidity of the optical cable, in the present invention, since the steel tube 1 itself serving as the loose tube 51 is a metal tube, it serves as a tension line. Will be done.

또한, 상기한 스틸 튜브(1)는 금속이기 때문에 외부의 충격에 대해서도 종래 플라스틱 재질인 루즈 튜브(51)에 비해 매우 강하게 되는 바, 상기한 스틸 튜브(1)의 두께를 얇게 제작하여도 금속의 특성상 충격, 항온, 압축 특성이 향상되는 것이다.In addition, since the steel tube 1 is made of metal, the steel tube 1 becomes very strong against external impact, compared to the conventional loose tube 51, and even when the thickness of the steel tube 1 is made thin, Impact, constant temperature, compression characteristics are improved.

여기서, 상기한 스틸 튜브(1)의 두께(0.3mm)가 종래 루즈 튜브(51)의 두께 (0.75mm)보다 얇기 때문에 광 케이블의 직경을 보다 작게 만들 수 있게 된다.Here, since the thickness (0.3 mm) of the steel tube 1 is thinner than the thickness (0.75 mm) of the conventional loose tube 51, the diameter of the optical cable can be made smaller.

스틸 튜브(1)의 내부에 광섬유(50)가 내재된 상태로 압출 성형되면, 그 외부에 재킷(53)을 씌워서 직경이 종래에 비해 매우 작게 형성된 광케이블을 완성할 수있게 된다.When the extrusion is molded in a state in which the optical fiber 50 is in the interior of the steel tube (1), it is possible to complete the optical cable formed with a very small diameter compared to the conventional by covering the jacket 53 on the outside thereof.

광케이블의 구성이 단순하게 되고, 직경이 작아지게 되면, 상기한 광케이블 전체의 부피가 작아짐과 아울러 광케이블의 운송, 설치 작업이 보다 편리하게 된다.When the configuration of the optical cable is simplified and the diameter is reduced, the volume of the entire optical cable is reduced and the transportation and installation work of the optical cable becomes more convenient.

이상과 같이 본 발명은 리본 튜브형 광케이블을 제작할 때, 비교적 얇게 금속인 스틸 튜브를 압출 성형함과 동시에 그 중심에 광섬유를 같이 압출함으로써, 광케이블의 부피를 감소시키고, 구성을 단순화하면서도 광케이블의 인장력을 유지할 수 있는 장점이 있다.As described above, according to the present invention, when manufacturing a ribbon tube optical cable, by extruding a relatively thin metal steel tube and extruding the optical fiber at the center thereof, the volume of the optical cable is reduced, and the configuration is simplified while maintaining the tensile force of the optical cable. There are advantages to it.
