본 고안은 광섬유 융착 접속기에서 광섬유의 절단측면 및 단면 상태를 동시에 관측할 수 있는 광섬유 절단면 관측장치에 관한 것이다.The present invention relates to an optical fiber cutout observation device capable of simultaneously observing the cutting side and the cross-sectional state of the optical fiber in the optical fiber fusion splicer.

광섬유는 중심부의 원형 코어(Core)와 주변부의 콜래딩(cladding)으로 구성되어 있으며 두 광섬유를 접속할 때 전송손실을 최소한으로 줄이려면 그 절단면이 광섬유 축에 수직인 깨끗한 거울면을 형성하여야 하며 또한 두 광섬유의 코어가 정확하게 일치하여야 한다.The fiber consists of a circular core in the center and a cladding around the periphery. To minimize transmission losses when connecting two fibers, the cut plane must form a clean mirror surface perpendicular to the axis of the fiber. The core of the fiber must match exactly.

그러나 종래의 접속기는 현미경을 통해 광섬유 축에 평행한 두 측면만을 관측할 수 있을 뿐 절단면의 상태를 관측할 수 없으므로 접속하려는 광섬유의 코어가 진원형에서 벗어나 타원형이 되거나 혹은 콜레딩과 코어의 중심이 일치하지 않는 편심일 경우 이를 확인할 수가 없다.However, the conventional splicer can only observe two sides parallel to the optical fiber axis through the microscope, but cannot observe the state of the cut surface. Therefore, the core of the optical fiber to be spliced becomes elliptical or out of a circular shape, or the center of the colling and core is Inconsistent eccentricity cannot be confirmed.

따라서 이런 경우에는 접속된 두 광섬유의 코어가 서로 일치하지 않게 접속되어 전송손실이 대단히 커지게 되는 결점이 있었다.Therefore, in this case, there is a drawback that the cores of the two optical fibers connected are inconsistent with each other and the transmission loss becomes very large.

본 고안은 이와 같은 점을 감안하여 광섬유 지지대와 대향되게 45도로 경사진 반사경을 설치하여 접속작업현장에서 접속시에 광섬유의 절단측면 및 단면을 현미경으로 동시에 관측하여 단면의 이상 여부를 확인한 후에 접속할 수 있도록한 것이다.In consideration of this, the present invention installs a reflecting mirror inclined at 45 degrees to face the optical fiber support, and at the time of connection at the work site, the side and the cross section of the optical fiber are simultaneously observed under a microscope to check the abnormality of the cross section. To be.

본 고안의 구성을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Referring to the configuration of the subject innovation in detail as follows.

기대(1)에 2조의 광섬유 지지대(2,2')와 현미경(3) 및 전극봉 지지대(4)를 설치한 공지의 광섬유 접속기에 전극봉 지지대 미동장치(8)에 경첩(7)으로 고정한 지지대(5)의 단부에 유리판에 금속코팅(coating)을 하여 만든 반사경(6)을 45도 각도로 코팅된 면이 위로 향하도록 부착하여서 된 것이다.A support fixed by a hinge (7) to the electrode support microscopic device (8) in a known optical fiber connector provided with two sets of optical fiber supports (2, 2 '), a microscope (3) and an electrode support (4) on the base (1). At the end of 5), the reflector 6 made by metal coating on the glass plate was attached to the coated surface at a 45 degree angle upward.

미설명 부호 9는 손잡이, F는 광섬유, m은 광섬유 단면의 허상이다.Reference numeral 9 is a handle, F is an optical fiber, m is a virtual image of the optical fiber cross section.

본 고안의 작용을 설명하면 광섬유 지지대(2) 현미경(3) 및 전극봉 지지대 미동장치(8)를 통상적인 방법으로 조절하여 관측하면 기하 광학적 원리에 따라 제3도와 같이 광섬유(F)가 반사경(6)의 코팅된면에 반사되어 그 단면이 허상(m)의 위치에서 보이게 되며 또한 직접 현미경을 통해 광섬유(F)가 보이므로 현미경에는 제4도와 같이 절단측면(F)과 단면(m)이 동시에 관측된다.Referring to the operation of the present invention, when the optical fiber support (2) microscope (3) and electrode support microscopic device (8) is adjusted and observed in a conventional manner, the optical fiber (F) as shown in FIG. ), The cross section is visible at the position of the virtual image (m) and the optical fiber (F) is directly seen through the microscope. Therefore, the cutting side (F) and the cross section (m) are simultaneously shown in FIG. Is observed.

이때 광섬유의 단면에 코어의 편심이나 일그러짐등 이상이 있으면 다시 커팅하여 관측하고 이상이 없으면 다른쪽 광섬유를 이상과 같은 방법으로 관측한 후 접속하게 된다.At this time, if there is an abnormality such as an eccentricity or distortion of the core in the cross section of the optical fiber, it is cut again and observed. If there is no abnormality, the other optical fiber is observed in the same way as above and then connected.

이와 같이 본 고안은 간단한 구성으로 광섬유의 절단면의 상태를 직접 접속현장에서 관측하여 그 절단면이 정확한 상태로 된 것만을 접속하게 되므로 종래보다 접속 손실을 일층 적게할 수 있다.In this way, the present invention can observe the state of the cut surface of the optical fiber in a simple configuration in the direct connection site, so that only the cut surface is connected to the correct state, so that the connection loss can be further reduced.
