Description

광케이블{Optic cable}Optical cable

본 발명은 광케이블에 관한 것으로, 더욱 상세하게는 광섬유 다발의 외부를 전도성 케이블로 감싸 광신호와 함께 전기적 신호 및 전원을 광케이블이 함께 전송하도록 한 광케이블에 관한 것이다.The present invention relates to an optical cable, and more particularly, to an optical cable that wraps the outside of the optical fiber bundle with a conductive cable to transmit an electrical signal and power together with the optical signal.

일반적으로 광케이블(1)은 도 1에 도시된 바와 같이 석영 등과 같은 소재로 만든 가는 광섬유들(15)을 몇백 가닥씩 묶은 광섬유 다발(10)과, 광섬유 다발(10)의 외부를 감싸는 절연성 피복(30)으로 구성된 것으로, 광다이오드를 통해 전기적 신호를 광신호로 변환시켜 소정의 장소까지 광신호를 빛의 속도로 전송한다.In general, the optical cable 1 includes an optical fiber bundle 10 in which hundreds of thin optical fibers 15 are made of a material such as quartz and the like, and an insulating coating surrounding the outside of the optical fiber bundle 10 as shown in FIG. 1. 30), converts an electrical signal into an optical signal through a photodiode and transmits the optical signal at a speed of light to a predetermined place.

따라서, 광케이블은 고속, 대용량의 데이터를 전송할 수 있고, 전송도중 광신호의 변화가 극히 적은 장점이 있을 뿐만 아니라 동이나 알루미늄으로 만든 일반 케이블에 비해 값이 싸며, 비금속이기 때문에 전자파에 의한 노이즈가 발생되지 않는다.Therefore, the optical cable can transmit high speed and large capacity, and it has the advantage that the change of the optical signal is very small during transmission, and it is cheaper than the general cable made of copper or aluminum, and the noise is caused by electromagnetic waves because it is a nonmetal. It doesn't work.

이와 같은 장점을 가지고 있어 광케이블은 데이터의 장거리 전송을 목적으로 보편화되어 있지만, 최근에는 시스템과 시스템을 연결하는 단거리 전송에도 많이 사용되고 있다.Due to these advantages, optical cables are widely used for long-distance transmission of data, but in recent years, they have been widely used for short-distance transmissions connecting systems with systems.

여기서, 장거리 전송에 광케이블을 사용하는 경우 주로 데이터 전송을 목적이기 때문에 광 다이오드를 이용하여 전기적 신호를 모두 광신호로 변화시켜 원하는 장소까지 전송하지만, 단거리에 전송에 광케이블을 사용하는 경우에는 일부 전기적 신호 및 전원을 같이 전송시켜야 한다.Here, when the optical cable is used for long-distance transmission, mainly for data transmission, all the electrical signals are converted into optical signals using optical diodes and transmitted to the desired place, but when the optical cable is used for short-distance transmission, some electrical signals are used. And power must be transmitted together.

그러나, 전기적 신호, 예를 들어 아날로그 신호 및 전원은 광데이터로 변화하지 못하기 때문에 광케이블과 전압 및 아날로그 신호를 전송하는 일반적인 케이블이 별도로 이용되는 문제점이 있다.However, since an electrical signal, for example, an analog signal and a power supply, cannot be changed into optical data, there is a problem in that an optical cable and a general cable for transmitting a voltage and an analog signal are separately used.

따라서, 본 발명의 목적은 상기와 같은 문제점을 감안하여 안출된 것으로써, 광케이블 하나만으로 광신호와 전기적 신호(아날로그 신호) 및 전압을 전달하수 있도록 하는데 있다.Accordingly, an object of the present invention has been made in view of the above problems, it is to be able to transfer optical signals, electrical signals (analog signals) and voltage with only one optical cable.

도 1은 종래의 광케이블의 구조를 개략적으로 도시한 단면도.1 is a cross-sectional view schematically showing the structure of a conventional optical cable.

도 2는 본 발명에 의한 광케이블의 구조를 개략적으로 나타낸 단면도.2 is a cross-sectional view schematically showing the structure of an optical cable according to the present invention.

이와 같은 목적을 달성하기 위해서 본 발명은 광 데이터를 전송하는 광섬유들의 묶음을 전기적 신호 및 전압을 전송할 수 있도록 전도성 케이블로 감싸고 전도성 케이블을 보호하기 위해서 전도성 케이블의 외부를 절연성 피복으로 감싼다.In order to achieve the above object, the present invention wraps a bundle of optical fibers for transmitting optical data with a conductive cable to transmit electrical signals and voltages, and wraps the outside of the conductive cable with an insulating coating to protect the conductive cable.

이하, 본 발명에 의한 광케이블의 구조를 첨부된 도면 도 2를 참조하여 설명하면 다음과 같다.Hereinafter, the structure of the optical cable according to the present invention will be described with reference to the accompanying drawings.

도 2에 도시된 바와 같이 광케이블(100)은 광섬유 다발(110), 광섬유 다발(110)을 감싸는 도전성 케이블(120) 및 도전성 케이블(120)을 감싸는 절연성 피복(130)으로 구성된다.As shown in FIG. 2, the optical cable 100 includes an optical fiber bundle 110, a conductive cable 120 surrounding the optical fiber bundle 110, and an insulating coating 130 surrounding the conductive cable 120.

여기서, 광섬유 다발(110)은 석영과 같은 비금속 재질로 광섬유(115)를 가늘고 길게 형성한 다음 광섬유(115)들을 수백 가닥씩 묶어 형성한 것으로, 전기적 신호가 광다이오드를 통해 변환된 광신호를 전송한다.Here, the optical fiber bundle 110 is formed by forming a thin and long optical fiber 115 made of a non-metal material such as quartz, and then bundles the optical fibers 115 by several hundred strands, and transmits an optical signal in which an electrical signal is converted through an optical diode. do.

또한, 도전성 케이블(120)은 광섬유 다발(110)의 외부를 감쌀 수 있도록 동과 같은 금속재질을 이용하여 내부 중심이 빈 파이프 형상으로 형성한 것으로, 광신호로 변환할 수 없는 전원 및 전기적 신호, 예를 들어 아날로그 신호등을 전송한다.In addition, the conductive cable 120 is formed in a hollow pipe shape using a metal material such as copper so as to surround the outside of the optical fiber bundle 110, the power and electrical signals that can not be converted into an optical signal, For example, it transmits an analog signal light.

한편, 절연성 피복(130)은 광섬유 다발(110) 및 도전성 케이블(120)을 외부환경으로부터 보호한다.On the other hand, the insulating coating 130 protects the optical fiber bundle 110 and the conductive cable 120 from the external environment.

이와 같이 구성된 광케이블의 작용을 개략적으로 설명하면 다음과 같다.Referring to the operation of the optical cable configured as described above is as follows.

전기적 신호가 광 다이오드를 통과하는 동안 광신호로 변환되어 광섬유 다발(110)을 이루는 각각의 광섬유들(115)로 전달되면, 각각의 광섬유들(115)이 광케이블(100)에 의해 연결된 소정의 시스템까지 광신호를 전달한다.When an electrical signal is converted into an optical signal while passing through a photodiode and transmitted to each of the optical fibers 115 constituting the optical fiber bundle 110, a predetermined system in which each of the optical fibers 115 is connected by the optical cable 100. To transmit the optical signal.

그리고, 광다이오드를 통과하지 않은 일부 전기적 신호, 예를 들어 아날로그 신호 및 전원은 광섬유 다발(110)을 감싸고 있는 도전성 케이블(120) 쪽으로 전달되어 광케이블(100)과 연결되어 있는 소정의 시스템으로 전달된다.In addition, some electrical signals that do not pass through the photodiode, such as analog signals and power, are transferred toward the conductive cable 120 surrounding the optical fiber bundle 110 to a predetermined system connected to the optical cable 100. .

따라서, 하나의 광케이블(100)을 이용하여 전기적 신호와 전압 및 광 신호를 원하는 소정장소까지 전송할 수 있다.Therefore, the electrical signal, the voltage, and the optical signal can be transmitted to a desired place by using one optical cable 100.

이상에서 설명한 바와 같이 본 발명은 광섬유 다발을 도전성 재질의 케이블로 감쌈으로써, 하나의 광케이블로 광신호 및 전기적 신호와 전원을 원하는 소정의 시스템까지 전송할 수 있는 효과가 있다.As described above, the present invention has the effect of transmitting the optical signal, the electrical signal, and the power source to a desired system by wrapping the optical fiber bundle with a conductive material cable.
