Abstract

최근의 광LAN, 광CATV, 광통신등의 회로분배 및 결합은 1×M형에서 2×M형으로 바뀌고 있고, 일부는 실용화되고 있다. 특히, 2×M광섬유커플러는 광출력의 모니터링, 응급조치, 쌍방향통신, 광출력의 제어등에 적용할 수 있으며, 계속적으로 그 응용이 증가할 것으로 기대된다. 본 발명에 의한 광섬유커플러는 종래의 광섬유커플러에 비해서 각각의 패키징 및 전체결합을 위한 새로운 접속부 없이 한 번만의 패키징으로 가능하여 제작시 원부재를 절약할 수 있으며 공정이 줄어 경제적이다. 또한, 종래의 단일공정에 의해서 제작된 트리형광섬유커플러는 2개의 입력단자가 기하학적으로 어려웠던 점에 비해서 본 발명의 2×M 광섬유커플러는 2개의 결합부를 이용하여 입력부의 단자를 2개 이상으로 할 수도 있다. 그러므로, 단일공정에 의한 트리형 광섬유커플러에서는 실현이 거의 거의 힘든 2×M 광섬유커플러가 가능한 장점이 있다. 또한, 광도파로형 커플러에서와 같이 광섬유를 도파로와 광학적으로 정열하는 공정이 필요없다. 그 광섬유커플러는 2개의 입력광신호를 M개의 출력광신호로 분배하거나 역으로 M개의 입력광신호를 2개의 출력광신호로 결합하기 위한 광섬유커플러에 있어서, 적어도 2개 이상의 결합부를 포함하여 광섬유를 분배 또는 결합되도록 구성되며, 그 제조방법은 2개의 입력광신호를 M개의 출력광신호로 분배하거나 역으로 M개의 입력광신호를 2개의 출력광신호로 결합하기 위한 광섬유커플러의 제조방법에 있어서, 적오도 2개 이상의 결합부를 하나의 제조장치를 이용한 단일 공정에 의해 수행한다.In recent years, circuit distribution and coupling of optical LAN, optical CATV, optical communication, etc. have been changed from 1 × M type to 2 × M type, and some have been put into practical use. In particular, the 2xM optical fiber coupler can be applied to the monitoring of light output, emergency measures, two-way communication, control of the light output, and is expected to increase its application continuously. Compared with the conventional optical fiber coupler, the optical fiber coupler according to the present invention can be packaged only once without a new connection for each packaging and total coupling, thereby saving raw materials during manufacturing, and reducing the process and economical. In addition, the tree optical fiber coupler manufactured by the conventional single process has two input terminals geometrically difficult, whereas the 2 × M optical fiber coupler of the present invention uses two coupling portions to make two or more terminals of the input unit. It may be. Therefore, there is an advantage that a 2 x M optical fiber coupler is hardly realized in a tree optical fiber coupler by a single process. Also, as in the optical waveguide coupler, a process of optically aligning the optical fiber with the waveguide is unnecessary. The optical fiber coupler is an optical fiber coupler for distributing two input optical signals into M output optical signals or conversely combining the M input optical signals into two output optical signals, the optical fiber coupler comprising at least two coupling portions to connect the optical fibers. In the manufacturing method of the optical fiber coupler for distributing or combining, the manufacturing method is for distributing two input optical signals into M output optical signals or conversely combining the M input optical signals into two output optical signals, At least two joining portions are performed by a single process using one manufacturing apparatus.
