Description
본 발명은 광섬유의 접속에 관한 것으로, 특히 광섬유를 융착접속한 부위를 보호하는 방법 및 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the connection of optical fibers, and more particularly, to a method and apparatus for protecting a fusion spliced portion of an optical fiber.
통상적으로 광섬유를 이용한 통신방식은 여타 금속케이블을 이용한 통신방식보다 광대역, 저손실, 보안성, 적은부피, 적은무게등인 장점이 있어 요즘 널리 사용되는 추세이다. 그러한, 광섬유 통신방식은 다수의 광학소자들을 접속하여 통신을 수행하기 때문에 그 전송매체인 광섬유와 상기 다수의 광학소자들에 연장된 광섬유들간의 접속부위에서 유발되는 접속손실이 있었다. 그러므로 상기 접속손실을최소화하기 위해 여러가지의 접속방식들이 사용되었으며, 그러한 접속방식에는 일반적으로 융착접속, 기계적접속, 커넥터접속이 있으나 비교적 접속손실이 적은 융착접속을 주로 사용한다.In general, the communication method using the optical fiber has the advantages of broadband, low loss, security, less volume, less weight than the communication method using other metal cable is a widely used trend these days. Since the optical fiber communication method performs communication by connecting a plurality of optical elements, there is a connection loss caused at the connection between the optical fiber which is the transmission medium and the optical fibers extending to the plurality of optical elements. Therefore, various connection methods have been used to minimize the connection loss, and such connection methods generally include a fusion connection, a mechanical connection, and a connector connection, but mainly use a fusion connection with a relatively low connection loss.
이때, 상기와 같은 융착접속을 시행하여 광섬유를 융착접속한 후 도 1a∼도 1b 및 도 2a∼도 2b와 같은 열수축 튜브를 사용하여 그 융착접속 부위를 보호하도록 하였다.At this time, the fusion splicing was performed by the above-described fusion splicing to protect the fusion splicing portion by using a heat shrink tube as shown in FIGS. 1A to 1B and 2A to 2B.
먼저, 도 1a∼1b는 광섬유의 융착접속한 부위를 열수축 튜브(tube)내에 삽입시킨 상태를 보여주는 도면으로서, 도 1a는 사시도이고, 도 1b는 단면도이다. 그리고, 도 2a∼도 2b는 상기 도 1a∼1b과 같이 광섬유의 융착접속한 부위를 삽입시킨 열수축튜브에 열을 가해 내부 광섬유의 융착접속부와 열수축튜브를 압착시킨 상태를 보여주는 도면으로서, 도 2a는 사시도이고, 도 2b는 단면도이다.First, FIGS. 1A to 1B show a state in which a fusion spliced portion of an optical fiber is inserted into a heat shrink tube. FIG. 1A is a perspective view and FIG. 1B is a sectional view. 2A to 2B are views showing a state in which a heat shrink tube in which a fusion spliced portion of an optical fiber is inserted is pressed to heat the fusion splicing portion and the heat shrink tube of an internal optical fiber as shown in FIGS. 1A to 1B. It is a perspective view, and FIG. 2B is a sectional view.
그러므로, 도 1a∼도 1b 및 도 2a∼도 2b를 참조하면, 먼저 열수축 튜브(10)내에는 내측튜브(4)와 외측튜브(2)를 구비하여 상기 내측튜브(4)의 내부에는 두 광섬유를 접속한 접속부위가 삽입되고, 상기 외측튜브(2)의 내부에는 두 광섬유를 접속한 접속부위를 보호하는 스틸(steel)재질의 보강재가 삽입된다. 따라서, 상기 열수축 튜브(10)에 열을 가해 내부의 외측튜브와 광섬유사이의 공간과 내측튜브와 보강재 사이의 공간을 압착시켜 상기 두 광섬유를 접속한 접속부위를 보호하도록 한다.Therefore, referring to FIGS. 1A-1B and 2A-2B, first, an inner tube 4 and an outer tube 2 are provided in the heat shrink tube 10 so that two optical fibers are provided inside the inner tube 4. Is connected to the connection portion, and the inside of the outer tube (2) is inserted into the reinforcing material of steel (steel) to protect the connection portion connecting the two optical fibers. Therefore, heat is applied to the heat shrink tube 10 to compress the space between the inner outer tube and the optical fiber and the space between the inner tube and the reinforcing material to protect the connection portion connecting the two optical fibers.
하지만, 상술한 바와 같이 상기 다수의 광학소자들에 연장된 광섬유와 광섬유를 접속한 부위를 보호하기 위해 열수축튜브를 사용한 경우 그 자체의 부피가 비대해지기 때문에 다수의 광학소자들을 내장한 광학부 자체의 부피도 역시 크게 설계 해야하는 문제점을 내포하고 있다.However, as described above, when the heat-shrink tube is used to protect the optical fiber that is extended to the plurality of optical elements and the portion where the optical fiber is connected, the volume of the heat shrink tube becomes large, so that the optical unit itself includes a plurality of optical elements. The volume also has a problem that must be designed large.
따라서 본 발명의 목적은 다수의 광학소자들에 연장된 광섬유와 전송매체인 광섬유를 융착접속한 접속부위를 보호하면서 그 부피를 줄일 수 있는 보호용장치 및 방법을 제공함에 있다.Accordingly, an object of the present invention is to provide a protective device and a method for reducing the volume of the optical fiber that is extended to a plurality of optical elements and the connection of the optical fiber which is a transmission medium.
상기 목적을 달성하기 위한 본 발명은 광섬유의 융착접속부 보호방법에 있어서; 상기 광섬유의 융착접속부가 삽입되는 모세관을 장착하고, 그 융착접속부와 모세관 사이의 공간을 고정시키기 위한 유.브이(UV)경화액을 주입하고, 유.브이(UV)광원을 조사시켜 상기 유.브이(UV)경화액을 경화시킴을 특징으로 한다.The present invention for achieving the above object is a method for protecting the fusion splicing portion of the optical fiber; And a capillary tube into which the fusion spliced portion of the optical fiber is inserted, injecting a UV curing agent for fixing the space between the fusion spliced portion and the capillary, and irradiating the UV V light source. It is characterized by curing the V-curing solution.

도 3은 본 발명의 실시예에 따른 광섬유를 융착접속한 부위에 유리재질의 모세관을 장착한 일부 절개사시도이다. 도 3을 참조하면, 먼저, 모세관(30)은 광학소자의 여장인 광섬유와 전송매체인 광섬유를 융착접속한 부위(8)를 삽입할 수 있는 크기의 내부 홀을 구비하고, 그 홀의 일측 개부부는 콘(corn)형태를 이루고 있어 상기 광섬유의 삽입이 용이 하도록 한다. 또한, 상기 모세관(30)의 재질은 상기 융착접속된 부위(8)를 보호할 수 있는 유리재질을 사용한다. 그리고, 경화액(34)는 상기 모세관(30) 내부의 홀에 삽입되어 외부에서 UV(ultraviolet)광원을 조사할 시 경화되어 모세관(30)과 상기 융착접속된 부위(8)를 고정한다. 이때, 상기 모세관(30)의 일 실시예를 도 4a 및 도 4b의 단면도를 통해 설명한다.3 is a partially cut perspective view of a glass capillary mounted on a fusion spliced optical fiber according to an embodiment of the present invention. Referring to FIG. 3, first, the capillary tube 30 has an inner hole of a size into which a portion 8 in which the optical fiber, which is an optical element of the optical element, and the optical fiber, which is a transmission medium, can be fused, is inserted, and one side of the hole The cone (corn) is made to facilitate the insertion of the optical fiber. In addition, the material of the capillary 30 uses a glass material that can protect the fusion-connected portion (8). In addition, the curing liquid 34 is inserted into a hole in the capillary 30 and cured when irradiated with UV (ultraviolet) light source from the outside to fix the capillary tube 30 and the fusion-spliced part 8. At this time, an embodiment of the capillary 30 will be described with reference to the sectional views of FIGS. 4A and 4B.
도 4a 및 도 4b는 본 발명의 실시예에 따른 광섬유를 융착접속한 부위를 보호하는 유리재질의 모세관의 단면도로서, 도 4a는 모세관(30)의 정단면도를 보여주고, 도 4b는 모세관(30)의 측단면도를 보여준다. 따라서, 본 도면에 제시되는 모세관(30)은 일실시예를 보여준다. 그러므로, 상기 모세관(30)의 내부 홀의 내경을 0.26±0.005㎜, 모세관(30)의 외경을 1.8㎜, 모세관의 가로길이를 15㎜, 모세관의 일측 개구인 콘의 가로길이는 3.0±1㎜로 한다.4A and 4B are cross-sectional views of a capillary tube made of a glass material for protecting a fusion spliced optical fiber according to an embodiment of the present invention. FIG. 4A shows a front cross-sectional view of the capillary tube 30, and FIG. 4B shows a capillary tube 30. Side cross-sectional view of Thus, the capillary 30 shown in this figure shows one embodiment. Therefore, the inner diameter of the inner hole of the capillary tube 30 is 0.26 ± 0.005 mm, the outer diameter of the capillary tube 30 is 1.8 mm, the horizontal length of the capillary tube is 15 mm, and the horizontal length of the cone, which is one side opening of the capillary tube, is 3.0 ± 1 mm. do.
따라서, 상기와 같은 모세관(30)을 광섬유의 융착접속부(8)에 고정하는 수순은 다음과 같다. 먼저, 광학소자의 여장인 광섬유를 상기 모세관(30)의 콘 형태의 일측 개구방향으로 삽입한 후 전송매체인 광섬유와 융착접속한다. 그런후, 상기 융착접속한 부위(8)의 중심부위로 상기 모세관(30)의 중심을 이동시키고, 상기 모세관(30)의 내부 홀에 UV(ultraviolet)경화액(즉, 자외선에 의해 경화됨)을 삽입한 후 외부에서 UV광원을 조사시켜 경화하고, 상기 융착 접속한 부위(8)와 모세관(30)을 고정하도록 한다.Therefore, the procedure for fixing the capillary 30 as described above to the fusion spliced portion 8 of the optical fiber is as follows. First, the optical fiber, which is the length of the optical element, is inserted in one side of the cone-shaped opening of the capillary tube 30 and then fusion-spliced with the optical fiber, which is a transmission medium. Then, the center of the capillary 30 is moved onto the center of the fusion spliced portion 8, and UV (ultraviolet) curing solution (ie, cured by ultraviolet rays) is applied to the inner hole of the capillary tube 30. After the insertion, the UV light source is irradiated and cured from the outside, and the fusion spliced portion 8 and the capillary tube 30 are fixed.
결론적으로, 광학소자의 여장인 광섬유와 전송매체인 광섬유를 융착접속한 부위(8)를 경화액(34)과 모세관(30)을 이용하여 보호함으로서, 다수의 광학소자를 구비하는 광학부를 설계할 시 그 크기를 비교적 작게 구성할 수 있다.In conclusion, the optical part including a plurality of optical elements can be designed by protecting the part 8 in which the optical fiber, which is an optical element of the optical element, and the optical fiber, which is a transmission medium, by fusion solution 34 and the capillary tube 30 are protected. The size can be made relatively small.
