Description
본 발명은 광전송시스템과 광선로감시시스템을 결합하거나 분리할 수 있는 탭 커플러에 관한 것이다. The present invention relates to a tap coupler capable of combining or disconnecting an optical transmission system and an optical path monitoring system.
FTTH(fiber to the home) 기술은 각 가정까지 광선로를 포설하여 초고속서비스를 제공하기 위한 기술로서, 전화국에서 가입자까지 광선로가 인입되고, 이를 이용하여 방송, 통신 융합 서비스를 하게 되면 광선로 관리에 대한 중요성이 커지게 된다. 광선로 관리를 위하여 광신호 중 일부 광신호를 분기하여 감시해야 하는데, 광신호를 분기 또는 결합시키는 기능을 수행하는 것이 가입자형 광분배반(OFD: optical fiber distributor)이다.FTTH (fiber to the home) technology is a technology to provide high-speed service by installing optical fiber to each home, and the optical fiber is introduced from the telephone company to the subscriber. The importance will increase. In order to manage the optical path, some optical signals of the optical signals need to be branched and monitored. The optical fiber distributor (OFD) performs the function of branching or combining the optical signals.
도 1은 종래의 가입자형 광분배반을 도시한 구성도이다.1 is a block diagram showing a conventional subscriber-type optical distribution panel.
가입자형 광분배반(OFD)은 일측에 위치한 하나의 광섬유(11)와 타측에 위치한 2개의 광섬유(12, 13)를 연결하는 탭 커플러(14)와, 탭 커플러(14)에 연결된 3개의 광섬유(11, 12, 13)와 외부의 광선로를 연결하는 3개의 어댑터(15, 16, 17)를 구비한다.Subscriber optical distribution panel (OFD) is a tap coupler 14 connecting one optical fiber 11 located on one side and two optical fibers 12, 13 located on the other side, and three optical fibers connected to the tap coupler 14 ( 11, 12, 13 and three adapters 15, 16, 17 for connecting the external optical path.
종래의 탭 커플러는 광섬유형 탭 커플러이기 때문에 그 크기가 크며, 이 광섬유형 탭 커플러를 이용하여 구축한 가입자형 광분배반의 경우, 입, 출력측에 광선로를 연결하려면 3개의 어댑터가 별도로 더 구비되어야 하기 때문에 한정된 면적에 많은 가입자를 수용하기 어려운 문제점이 있다. 전화국이 더 많은 가입자를 수용하려면 전화국을 확장해야 하며, 이럴 경우에는 많은 경제적 손실이 발생하게 되는 문제점이 있다. The conventional tap coupler is large in size because it is an optical fiber tap coupler. In the case of a subscriber-type optical distribution panel constructed using the optical fiber tap coupler, three adapters must be separately provided to connect an optical path to the input and output sides. Therefore, there is a problem that it is difficult to accommodate a large number of subscribers in a limited area. In order to accommodate more subscribers, the telephone company must expand the telephone station, which causes a lot of economic losses.
상기한 종래기술의 문제점을 해결하기 위하여 안출된 본 발명의 목적은 탭 커플러의 기능과 어댑터의 기능이 결합되어 소형화된 어댑터형 탭 커플러를 제공하기 위한 것이다. An object of the present invention devised to solve the above problems of the prior art is to provide a compact adapter-type tap coupler combined with the function of the tap coupler and the function of the adapter.
상기한 목적을 달성하기 위한 본 발명에 따른 어댑터형 탭 커플러는,Adapter type tap coupler according to the present invention for achieving the above object,
광신호를 결합 또는 분기시키는 Y도파로형 탭 커플러와,A Y waveguide tap coupler for coupling or branching an optical signal,
상기 Y도파로형 탭 커플러의 각 단부와 광 패치코드 사이에 삽입 고정되어 상기 Y도파로형 탭 커플러와 상기 광 패치코드를 커플링시키는 가이드부재와,A guide member inserted and fixed between each end of the Y waveguide tab coupler and the optical patch cord to couple the Y waveguide tab coupler to the optical patch cord;
상기 Y도파로형 탭 커플러 및 상기 가이드부재의 외부를 감싸는 어댑터케이스를 구비한 것을 특징으로 한다.It characterized in that it is provided with an adapter case surrounding the outside of the Y waveguide tab coupler and the guide member.
이하, 첨부된 도면을 참조하며 본 발명의 한 실시예에 따른 어댑터형 탭 커플러를 좀 더 상세하게 설명한다.Hereinafter, an adapter type tap coupler according to an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.
도 2는 본 발명의 한 실시예에 따른 어댑터형 탭 커플러를 도시한 구성도이다.2 is a block diagram illustrating an adapter-type tap coupler according to an embodiment of the present invention.
본 발명에 따른 어댑터형 탭 커플러는 Y도파로형 탭 커플러(21)와, 상기 Y도파로형 탭 커플러(21)의 각 단부와 광 패치코드(24) 사이에 삽입 고정되어 Y도파로형 탭 커플러(21)와 광 패치코드(24)를 커플링시키는 가이드부재(23a, 23b, 23c)와, 이 Y도파로형 탭 커플러(21) 및 가이드부재(23a, 23b, 23c)의 외부를 감싸는 어댑터케이스(22)를 구비한다.The adapter type tap coupler according to the present invention is inserted between the Y waveguide type tap coupler 21 and each end of the Y waveguide type tap coupler 21 and the optical patch cord 24 to be fixed to the Y waveguide type tap coupler 21. ) And a guide member (23a, 23b, 23c) for coupling the optical patch cord 24, and the adapter case (22) surrounding the outside of the Y waveguide-type tap coupler 21 and the guide member (23a, 23b, 23c) ).
Y도파로형 탭 커플러(21)는 PLC(Planar Lightwave Circuit)를 이용하여 구성한다. Y도파로형 탭 커플러의 일측은 하나의 광 패치코드와 커플링되어 하나의 광선로가 연결되고, 타측은 두 개의 광 패치코드와 커플링되어 두 개의 광선로가 연결된다. 하나의 광선로로부터 입력되는 광신호를 M:N의 비율로 분기하여 두 개의 광선로로 출력하거나, 두 개의 광선로로부터 입력되는 광신호를 결합하여 하나의 광선로로 출력한다. 따라서, 이 어댑터형 탭 커플러의 각 광 패치코드(24)에 광선로를 연결하면 광신호를 결합 및 분기시킬 수 있다.The Y waveguide type tap coupler 21 is constructed using a PLC (Planar Lightwave Circuit). One side of the Y-waveguide tap coupler is coupled with one optical patch cord to connect one optical path, and the other side is coupled with two optical patch cords to connect two optical paths. The optical signal inputted from one optical beam is branched at a ratio of M: N and output to the two optical beams, or the optical signals input from the two optical beams are combined and output as one optical fiber. Therefore, by connecting optical paths to the optical patch cords 24 of the adapter-type tap coupler, optical signals can be combined and branched.
도 3과 도 4는 어댑터형 탭 커플러를 이용하여 구성한 광분배반(OFD)의 외형도이다. 광분배반의 전면판(31)은 도 3에 도시된 바와같이 2개의 포트로 구성되며, 광분배반의 후면판(32)은 도 4에 도시된 바와 같이 하나의 포트로 구성된다.3 and 4 are external views of an optical distribution panel (OFD) constructed using an adapter type tap coupler. The front panel 31 of the optical distribution panel is composed of two ports as shown in FIG. 3, and the rear panel 32 of the optical distribution panel is composed of one port as shown in FIG. 4.
도 5는 본 발명에 따른 어댑터형 탭 커플러를 FTTH에 적용한 예를 도시한 도면으로서, FTTH 환경에서 PON(Passive Optical Network) 또는 AON(Active Optical Network) 시스템(44)를 구축한 상태를 도시한다.FIG. 5 is a diagram illustrating an example in which an adapter-type tap coupler according to the present invention is applied to FTTH, and illustrates a state in which a passive optical network (PON) or an active optical network (AON) system 44 is constructed in an FTTH environment.
이 시스템은 OLT(Optical Line Terminal)(47), ODN(Optical Distributor Node)(48), ONT(Optical Node Termination)(49)로 구분된다.The system is divided into an Optical Line Terminal (OLT) 47, an Optical Distributor Node (ODN) 48, and an Optical Node Termination (ONT) 49.
OLT(47)는 본 발명에 따른 어댑터형 탭 커플러(41)를 이용하여 구성된 광분배반(42)과, PON 또는 AON시스템(44)과, 광선로감시시스템(45)로 이루어진다. 광분배반(42)은 광신호를 결합하여 광선로(46)를 통해 ONT(49)에게 전송하거나, ONT(48)로부터 입력되는 광신호를 분기하여 PON 또는 AON시스템(44) 및 광선로감시시스템(45)에게 전달한다.The OLT 47 is composed of an optical distribution panel 42 constructed using an adapter-type tap coupler 41 according to the present invention, a PON or AON system 44, and an optical path monitoring system 45. The optical distribution panel 42 combines the optical signals and transmits them to the ONT 49 through the optical path 46, or branches the optical signals input from the ONT 48 to the PON or AON system 44 and the optical path monitoring system ( 45).
ODN(48)은 광선로(46)를 통해 OLT(47)로부터 수신된 광신호를 분리(splitter)하거나 역다중(demultiplexer)하는 장비(43)로 구성된다. ONT(49)는 각 가입자 단말을 말한다.The ODN 48 consists of equipment 43 for splitting or demultiplexing the optical signal received from the OLT 47 via the optical path 46. ONT 49 refers to each subscriber station.
즉, 본 발명에 따른 어댑터형 탭 커플러는 OLT의 광분배반에 적용될 수 있다. 이때, 어댑터형 탭 커플러에 직접 광선로를 연결하면 충분하고 별도의 어댑터를 부착하지 않아도 되기 때문에 소형 제작이 가능하고, 동일한 상면적에 보다 많은 가입자를 수용할 수 있게 된다. That is, the adapter-type tap coupler according to the present invention can be applied to the optical distribution panel of the OLT. In this case, the direct connection of the optical path to the adapter-type tap coupler is sufficient, and since it is not necessary to attach a separate adapter, it is possible to manufacture a small size and to accommodate more subscribers in the same area.
이상에서 본 발명에 대한 기술 사상을 첨부 도면과 함께 서술하였지만, 이는 본 발명의 가장 양호한 일 실시예를 예시적으로 설명한 것이지 본 발명을 한정하는 것은 아니다. 또한, 이 기술 분야의 통상의 지식을 가진 자이면 누구나 본 발명의 기술 사상의 범주를 이탈하지 않는 범위 내에서 다양한 변형 및 모방이 가능함은 명백한 사실이다. Although the technical spirit of the present invention has been described above with reference to the accompanying drawings, it is intended to exemplarily describe the best embodiment of the present invention, but not to limit the present invention. In addition, it is obvious that any person skilled in the art may make various modifications and imitations without departing from the scope of the technical idea of the present invention.
이상과 같이 본 발명에 따르면, 어댑터형 탭 커플러는 소형 제작이 가능하여 이 어댑터형 탭 커플러를 이용하여 광분배반을 제작하면, 동일한 상면적에 더 많은 가입자를 수용할 수 있는 효과가 있다. As described above, according to the present invention, the adapter-type tap coupler can be manufactured in a small size, and if the optical distribution panel is manufactured using the adapter-type tap coupler, there is an effect of accommodating more subscribers in the same area.
