Description
본 발명은 광케이블과 광분배함, 광분배함에서 광장비까지 연결하는 다심광점퍼코드(Multi-fiber jumper cord)에 관한것이다. 더욱 자세하게는 광섬유코드인 단일모드점퍼코드(single mode jumper cord) 끼리(4∼8코어) 또는 단일모드점퍼코드와 다중모드점퍼코드(multi-mode jumper cord)를 각각 짝수개로 하여(4∼8코어) 1열로 코드사이의 연접부에 점착제를 기계적으로 발라서 수평으로 압압하면서 열건조통을 통과시켜 플랫코드케이블(flat cord cable)을 1개의 플랫코드(flat cord)로 제작하고 또 단일모드점퍼코드끼리(4∼8코어) 또는 단일모드점퍼코드와 다중모드점퍼코드를 각각 짝수개로 하여(4∼8코어) 2열로 병렬하여 코드사이의 연접부에 점착제를 기계적으로 발라서 수평 과 수직으로 압압하면서 열건조통을 통과시켜 라운드코드케이블(round cord cable)을 1개의 라운드코드(round cord)로 제작하는 다심광점퍼코드(multi-fiber jumper cord)에 관한 것이다.The present invention relates to an optical cable and an optical distribution box, a multi-fiber jumper cord (multi-fiber jumper cord) connecting from the optical distribution box to the square ratio. More specifically, single mode jumper cords (4 to 8 cores) or even number of single mode jumper cords and multi-mode jumper cords (4 to 8 cores), respectively, which are optical fiber cords. ) Apply a pressure sensitive adhesive to the joints between the cords in a single row and press them horizontally to pass through the heat-drying container to make a flat cord cable into a single flat cord, and single-mode jumper cords (4 to 8 cores) or even number of single mode jumper cords and multi mode jumper cords (4 to 8 cores) in parallel, and heat-dry while pressing them horizontally and vertically by applying adhesive on the joints between the cords. The present invention relates to a multi-fiber jumper cord for producing a round cord cable into one round cord by passing through a tube.
종래에는 광장비당 기존의 1코어 점퍼코드(jumper cord)는 4개를 설치하였는바, 즉 광장비(광단국장치)의 대부분은 송신1개, 수신1개, 예비송신1개, 예비수신1개로 4개의 연결포트로 연결하기 때문에 종래의 점퍼코드는 1코어로 4개의 점퍼코드를 각각 4회선으로 포설하여 설치하게 되므로 인건비가 많이 소요되고 여장정리와 코드선의 심선구분이 어려워 작업상 불편하며, 코드선의 교체 및 보수관리가 어려운 결점이 있었다.Conventionally, four conventional 1-core jumper cords per square ratio have been installed. That is, most of the square ratios (broadcasting station devices) are one transmission, one reception, one preliminary transmission, and one preliminary reception. Since the conventional jumper cords are installed by installing 4 jumper cords in 4 cores each with 4 lines, it costs a lot of labor cost, and it is inconvenient for work because it is difficult to arrange the dressing and the core line of the cord line. It was difficult to replace and repair the line.
또한 종래의 점퍼코드는 1코어(core)로 4개의 점퍼코드(jumper cord)를 각기 분리된체로 포설설치하게 되므로 코드배선작업시 코드선에 충격을 주게 될 경우 광섬유에 손상을 입히게 될 우려가 있고 또한 코드가 각기 늘어져있어 외관상 보기 흉한 결점도 있었다.In addition, the conventional jumper cords are installed with four jumper cords separated by one core, so that damage to the optical fiber may occur if the cord wires are impacted during the wiring. In addition, each of the cords were sloppy in appearance and had some unsightly flaws.
본 발명은 도6에 도시된 바와같이 공지된 단일 광섬유 또는 다중 광섬유 표면에 보호코팅(buffer)을 하고 다시 그 외주연에 인장력을 보강하기 위하여 케이블러로 둘러싸고, PVC 자켓(Jaket)을 입힌 단일모드점퍼코드(single mode jumper cord)와 다중모드점퍼코드(multi mode jumper cord)는 단일모드(single mode 이하 "SM" 이라함)용으로는 4∼8코어(core)로 구성되고, 단일모드와 다중모드(multi - mode 이하 "MM" 이라함) 연합용으로는 2코어 SM+ 2코어 MM 또는 4코어 SM + 4코어 MM으로 통상적으로 구성하며 MM과 SM의 연합비율은 구매자의 요청에 의하여 변경될 수도 있다.The present invention is a single mode in which a protective coating (buffer) on a known single optical fiber or multiple optical fiber surfaces, as shown in FIG. 6, is surrounded by a cabler to reinforce the tensile force on the outer circumference thereof, and a PVC jacket is coated. Single mode jumper cords and multi mode jumper cords consist of four to eight cores for single mode ("SM"), single mode and multiple For mode (multi-mode "MM") alliance, it is typically composed of two-core SM + two-core MM or four-core SM + four-core MM. The combined ratio of MM and SM may be changed at the request of the purchaser. have.
본 발명은 상기한 문제점을 해소하기 위한 것으로 본 발명에서는 도1 및 도3에 도시된 바와같이 SM코드 또는 MM코드, SM코드 와 MM코드를 4∼8개를 수평으로 연접시켜서 도5와 같이 연접부에 점착제를 기계적으로 발라서 열건조통을 거쳐 플랫코드케이블(flat cord cable)을 1개의 플랫코드(flat cord)로 제작하거나, 도2 및 도4와 같이 SM코드 또는 MM코드, SM코드와 MM코드 4∼8개를 2줄로 연접시켜서 도5와 같이 연접부에 점착제를 발라서 열건조통을 거쳐서 1개의 라운드코드(round cord)을 제작하고, SM코드 또는 MM코드에 의한 라인표시를 숫자마킹하여 다심광점퍼코드(multi-fiber jumper cord)를 제작함으로서 SM코드 또는 MM코드, SM,MM연합코드의 설치가 간편하고 인건비를 절약하며 여장정리와 코드선의 심선구분이 용이하여 작업이 편리하고 코드선의 교체 및 보수관리가 용이하도록 함에 그 목적이 있다.The present invention is to solve the above problems, in the present invention, as shown in Figures 1 and 3 by connecting four to eight SM code or MM code, SM code and MM code horizontally connected as shown in Figure 5 Mechanically apply adhesive to the part to make a flat cord cable into a single flat cord through a heat-drying barrel, or SM code or MM code, SM code and MM as shown in Figs. Four to eight cords are connected in two lines, and an adhesive is applied to the joints as shown in FIG. 5 to make one round cord through a heat-drying barrel, and the line markings by SM code or MM code are numerically marked. By manufacturing multi-fiber jumper cord, it is easy to install SM code, MM code, SM, MM union cord, save labor cost, and it is easy to work with the arrangement of cord and cord wire. Replacement and Maintenance As to which is the purpose.
종래에도 PVC 피복리드선은 플랫코드로 형성된 것이 있었으나, 이는 다수개의 리드선을 매입하여 압출성형하였기 때문에 단일색의 PVC를 피복할 수 밖에 없으므로 색채가 다른 PVC자켓을 피복한 광섬유코드인 SM코드(자켓의 색깔이 노랑색으로 세계공통임)와 MM코드(자켓의 색깔이 오렌지색으로 세계공통임)을 동시에 압출성형하는 것은 불가능하고 또한 고열로 압출성형할 경우 광섬유, 광섬유표면의 보호코팅, 케이블러 및 PVC자켓(jaket)이 손상되므로 광섬유코드인 SM코드나 MM코드를 연접시켜서 플랫코드로 제작할 때 압출성형은 불가능하였다.Previously, PVC coated lead wires were formed of flat cords, but since they were molded by extrusion of a plurality of lead wires, they had no choice but to cover a single color of PVC, which is an optical fiber cord coated with a different PVC jacket. It is not possible to simultaneously extrude the yellow color and the MM code (the color of the jacket is orange in the world) at the same time, and if it is extruded at high temperature, it is possible to protect the fiber, the surface of the fiber, the coating of the cable, and the PVC jacket ( Because of the damage to the jaket, extrusion molding was impossible when the SM cord or MM cord, which is optical fiber cords, were fabricated into flat cords.
따라서 본 발명의 또다른 목적은 SM코드와 MM코드 연합용으로 플랫(flat)형 또는 라운드(round)형으로 연접시켜서 점착제로 1개의 플랫코드 또는 1개의 라운드코드로 성형하여 다심광점퍼코드(multi-fiber jumper cord)를 제작함으로서 SM코드로 된 플랫코드일 경우, 필요에 따라 간편하게 분리하여 사용할 수 있고, 또한 SM코드와 MM코드의 연합형으로 플랫코드와 라운드코드를 점착제로 연접시켜서 제작함으로서 SM코드 또는 MM코드의 인장력을 증대시키는데 그 목적이 있다.Therefore, another object of the present invention is to connect a flat or round type for the SM code and MM code association, molded into one flat cord or one round cord with an adhesive, multi-core optical jumper cord (multi -In case of flat cord made of SM cord, it can be easily separated and used as needed.In addition, it is a combination of SM cord and MM cord. The purpose is to increase the tensile force of the cord or MM cord.
