Description

광점퍼코드{Optical Jumer Code}Optical Jumer Code

본 발명은 근거리에 위치한 장비간이나 광케이블과 전화국 등의 건물내의 배선단자 등과의 접속을 하기 위한 광점퍼코드(Optical Jumper Cord)에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical jumper cord for making connections between equipment located at a short distance, and wiring terminals in buildings such as optical cables and telephone stations.

최근 광통신 수요의 증가와 더불어 네트워크화의 증가 및 네트워크내에서의 사용자 수의 증가로 인해 단일의 광섬유가 고밀도로 집속된 광케이블의 사용이 증하고 있다. 이러한 광케이블은 유리나 합성수지의 가는 투명수지로 제작된 광섬유(Optical fiber)가 다수개 묶인 상태의 것으로서, 선로에서 장비로 또는 통신장비를 구비하는 건물내로 접속하기 위해 또는 전화국 등의 건물내에서 장비들간의 접속을 위해서 상기 광케이블은 광섬유의 양단으로 컨넥터부를 구비시킨 광점퍼코드가 접속되어 사용된다.Recently, due to the increase in the demand for optical communication, the increase of the network and the increase in the number of users in the network has increased the use of optical cables in which a single optical fiber is concentrated at a high density. The optical cable is a state in which a plurality of optical fibers made of thin transparent resin of glass or synthetic resin are bundled, and is connected between equipment in a building such as a telephone station or a building equipped with communication equipment or in a building such as a telephone station. For the connection, the optical cable is used by connecting an optical jumper cord having a connector part at both ends of the optical fiber.

그런데 관련 장비의 복잡화 및 통신수요의 증가와 더불어 광섬유의 묶음은 더욱 고밀도화 되고 있으며 이에 따라 상기 광섬유에 연결된 광점퍼코드 또한 다수의 묶음형태로 사용되고 있다. However, with the increase of the complexity of the related equipment and the demand for communication, the bundle of optical fibers is becoming more dense, and thus, an optical jumper cord connected to the optical fiber is also used in a plurality of bundle forms.

한편, 이러한 광점퍼코드는 장비 등과의 접속여부를 확인할 필요가 있는데, On the other hand, such an optical jumper cord needs to check whether or not connected to the equipment,

장비의 운용 중 특정한 단일 광섬유(광점퍼코드)의 결선여부를 확인하기 위해서는 장비의 운용을 중단하고 그 결선여부를 확인해야 하는 불편이 있었다. To check the connection of a single optical fiber (optical jumper cord) during the operation of the equipment, it was inconvenient to stop the operation of the equipment and check the connection.

이를 해소하기 위해 종래에는 광코드내에 동심선과 광심선을 함께 구비시켜 전기적인 전원을 이용하여 엘이디(LED)을 구동시킴으로써 양단의 광커넥터 부츠(boot)위에서 광코드의 결선을 식별가능하도록 고안되어 사용되었다.In order to solve this problem, conventionally, a concentric wire and an optical core are provided together in an optical cord to drive an LED using an electric power source, so that the wiring of the optical cord can be identified on the optical connector boots at both ends. It became.

그러나 상기 동심선과 광심선이 복합적으로 구비된 형태의 광코드의 경우, 결선여부를 확인키 위한 장비의 운용중단은 필요 없게 되었으나, 습기나 수분으로 인한 전기적인 장애 및 엘이디 램프의 장애 시에는 결선여부를 확인할 수 없게 되는 문제점이 있다.However, in the case of the optical cord having a combination of the concentric wire and the optical fiber, it is not necessary to stop the operation of the equipment to check the connection, but in the case of an electrical failure due to moisture or moisture and a failure of the LED lamp There is a problem that can not be confirmed.

그러므로, 본 발명의 제 1 목적은 결선식별용 광섬유를 구비하는 향상된 광점퍼코드를 제공하는 것이다. It is therefore a first object of the present invention to provide an improved optical jumper cord having an optical fiber for connection identification.

본 발명의 제 2 목적은 전기적인 장애를 일으키는 일이 없이 순수한 광원만으로도 결선여부를 식별할 수 있는 광점퍼코드를 제공하는 것이다. It is a second object of the present invention to provide an optical jumper code that can identify a connection with a pure light source without causing an electrical disturbance.

본 발명의 제 3 목적은 근거리내에서의 광통신용으로도 선택적으로 이용가능한 플라스틱광섬유를 포함하는 광점퍼코드를 제공하는 것이다.It is a third object of the present invention to provide an optical jumper cord comprising a plastic optical fiber which is also optionally available for optical communication in a short distance.

상기의 목적을 달성하기 위해 본 발명에 따른 광점퍼코드는 광코드부와 이 광코드부의 양단에 통상의 광컨넥터부를 구비하되, 상기 광코드부는 통신용 제 1 광심선과 결선(結線)식별용 플라스틱 제 2 광심선(Plastic Optical Fiber)을 하나의 외피안에 구비시킴을 특징으로 한다.In order to achieve the above object, the optical jumper cord according to the present invention includes an optical cord part and a normal optical connector part at both ends of the optical cord part, wherein the optical cord part is made of a plastic for identifying the first optical core wire for communication. It is characterized by including two optical fiber (Plastic Optical Fiber) in one shell.

여기서, 상기 제 1 광심선은 석영계광섬유(Glass Optical Fiber) 또는 플라스틱 광섬유(Plastic Optical Fiber)일 수 있다.Here, the first optical fiber may be a quartz optical fiber or a plastic optical fiber.

또한 상기 광컨넥터부에는 결선 검침용 디텍터를 사용하기 위한 결선식별용 검침홀이 구비될 수 있다.In addition, the optical connector portion may be provided with a wiring identification metering hole for using the wiring metering detector.

본 발명은 하나의 외피안에 통신용의 석영계 또는 플라스틱계 광심선(광섬유)과 결선식별용의 플라스틱 광심선을 함께 매입 구성시킨 것을 특징으로 한다. 상기 플라스틱계 광심선(광섬유)는 임의적으로 통신용으로도 사용될 수도 있다.The present invention is characterized in that a quartz or plastic optical fiber (optical fiber) for communication and a plastic optical fiber for connection identification are embedded together in one shell. The plastic optical fiber (optical fiber) may be optionally used for communication.

석영계 광섬유(GOF, Glass Optical Fiber)에 대해서는 공지된 것으로서 그 상세한 설명을 생략한다. Quartz-based optical fibers (GOFs) are well known and their detailed description is omitted.

본 발명은 플라스틱 광섬유을 통신용 또는 결선식별용으로 통신용 광섬유와 함께 하나의 외피안에 포함한다. 플라스틱 광섬유의 재료는 폴리메틸메타아크릴레이트(PMMA)나 폴리카보네이트계(系)의 수지가 중심이 되는데, 석영유리제 광섬유에 비하여 굵기가 5∼10배이고 신호의 전송거리도 200 m 정도로 짧지만, 광점퍼코드는 비교적 케이블과 장비간 또는 장비들간 비교적 짧은 거리상의 두 지점을 연결접속하는데 사용되는 것이기 때문에 플라스틱 광섬유를 사용할 수가 있다. 또한 굵기가 굵어 수광력(빛을 흡수하는 양)이 좋아, 일정한 거리내에서의 플라스틱 광섬유내의 일 지점에서 발생한 빛을 타 지점에서 식별하는데 훌륭한 재료로 사용할 수 있는 것이다.The present invention includes a plastic optical fiber in one shell together with a communication optical fiber for communication or connection identification. The material of plastic optical fiber is made of polymethyl methacrylate (PMMA) or resin of polycarbonate series. It is 5 ~ 10 times thicker than quartz glass optical fiber and the signal transmission distance is short as 200m. Because jumper cords are used to connect two points on a relatively short distance between cables and equipment or between equipment, plastic optical fibers can be used. In addition, the thickness is good, so the light receiving power (the amount of light absorption) is good, it can be used as an excellent material for identifying the light generated at one point in the plastic optical fiber within a certain distance at another point.

본 발명은 플라스틱 광섬유의 이와 같은 특징을 응용하여 통신용의 일반적인 석영유리제 광심선과 결선식별용의 플라스틱 광섬유를 하나의 외피안에 포함시킨 광점퍼코드를 제안하게된 것이다. 다만, 플라스틱 광섬유의 전송거리내에서는 상기 플라스틱 광섬유을 통신용으로도 선택적으로 사용가능함은 물론이다. The present invention proposes an optical jumper cord incorporating a common optical fiber of quartz glass for communication and a plastic optical fiber for connection identification in one shell by applying the above characteristics of the plastic optical fiber. However, within the transmission distance of the plastic optical fiber, the plastic optical fiber can be selectively used for communication.

또한 상기 플라스틱 광섬유는 수광력이 양호하여 일반 레이져포인터에서 발생하는 빛을 이용하여서도 결선여부를 식별할 수 있다. In addition, the plastic optical fiber has a good light receiving power so that it is possible to identify the wiring even by using light generated from a general laser pointer.

종래, 동심선과 엘이드(LED)를 사용하는 경우에는 습한 곳에서 오작동 내지 고장을 일으킬 수 있으나, 플라스틱 광섬유를 사용하는 경우에는 그러한 염려가 없다.Conventionally, when using a concentric wire and an LED (LED) may cause malfunction or failure in a wet place, but when using a plastic optical fiber there is no such concern.
