도3의 종래 1심 광케이블은 외피층(101)과 중심 광섬유 버퍼(Buffer)층 (103)사이에 보강재층(102)이 별도로 자리잡고 있는 3층 구조로 되어 있다. 외피층(101)의 재질로서 주로 사용되는 폴리우레탄 (Polyuretane) 고분자 합성수지는 고무처럼 잘 늘어나고 부드러워 내부 연약한 광섬유 버퍼(Buffer)층(103)을 인장, 압력등 외부 자극으로부터 보호하기 위하여 별도의 보강재층(102)이 배치된다. 실제 보강재(105)로서 아라미드얀(Aramid Yarn)이 널리 사용되는 데 이는 피아노선처럼 매우 강하고 거의 늘어나지 아니하되 실처럼 부드러워 중심 광섬유 버퍼(Buffer)층(103)을 인장,압력등 외부 자극으로부터 보호하는 역할을 한다. 도3의 종래 1심 광 케이블은 패치코드(Patch Cord)와 통신용으로 널리 사용되고 있는 데 실제 상용화된 제품들의 일반적인 규격은 외피층의 굵기는 3mm, 광섬유버퍼층은 0.9mm, 보강재의 인장강도는 60kg정도이고, 빛의 전송로 기능을 하는 광섬유의 굵기는 0.125mm이다. 광섬유 버퍼(Buffer)층(103)의 중심에 광섬유(104)가 견고히 밀착되어 있어 외부에서 광섬유 버퍼(Buffer)층(103)을 잡아당기면 내부 광섬유(104)도 함께 늘어나며 5kg정도의 인장력을 가하면 내부 광섬유(104)가 절단될 정도로 유약하다. 그러나 이를 침입감지 광망을 사용하는 데는 아래와 같이 근본적으로 부적합하다.
도4 종래 다이몬드형 광망(실용신안등록 제0205490호)은 구멍 격자점에서 두 인접 두 광 케이블(402)들은 격자쇠(401)에 의하여 상호 고정되고, 그 구멍크기는 통상 성인남자의 가슴둘레길이 (약85cm) 정도이다. 이러한 광망을 만약 가슴둘레길이 95cm의 침입자가 억지로 벌리고 통과 할 때 광망 구멍이 벌어지지 아니하고 절단되어 감지되도록 하는 것이 필수적인 요건이다. 종래 광망경비시스템 (특허제127361호)에 의하면 광망경비시스템이 침입을 감지하여 경보에 성공하려면 광망이 절단되어야 한다.
도3의 종래 1심 광 케이블을 사용하여 제작된 광망은 침입자가 구멍를 억지로 벌리고 통과하려할 때 격자쇠(401)에서 인접 두 광 케이블(402)의 외피층(101) 상호간은 격자쇠(401)과 함께 고정되었음에도 불구하고, 광망 구멍을 이루는 4변 광케이블(402)의 외피층(101)은 늘어나고 내부 보강재층(102)과 광섬유 버퍼(Buffer)층(103)이 격자쇠(401)로 부터 밀리며 이탈하여 광망 구멍이 침입자 몸통크기 이상으로 커져도 광 케이블(402)절단되지 아니하여 침입자의 통과를 감지하지 못하는 결함이 발생된다. The conventional single core optical cable of FIG. 3 has a three-layer structure in which a reinforcement layer 102 is separately located between the outer skin layer 101 and the central optical fiber buffer layer 103. Polyurethane (Polyuretane) polymer synthetic resin, which is mainly used as the material of the outer skin layer 101, is stretched and softed like a rubber so as to protect the internal soft optical fiber buffer layer 103 from external stimulus such as tension and pressure. 102 is disposed. Aramid Yarn is widely used as the actual reinforcing material 105, which is very strong like a piano wire and hardly elongated, but softly threaded to protect the central optical fiber buffer layer 103 from external stimuli such as tension and pressure. Play a role. The conventional single-core optical cable of Figure 3 is widely used for patch cord (communication) and communication, the general specifications of the commercially available products are the thickness of the outer layer 3mm, the optical fiber buffer layer 0.9mm, the tensile strength of the reinforcement is about 60kg The thickness of the optical fiber, which functions as a transmission of light, is 0.125mm. The optical fiber 104 is firmly adhered to the center of the optical fiber buffer layer 103 so that when the optical fiber buffer layer 103 is pulled from the outside, the internal optical fiber 104 also extends together and when the tensile force of about 5 kg is applied, The optical fiber 104 is fragile enough to be cut. However, it is fundamentally inadequate to use the intrusion detection optical network as follows.
4, a conventional diamond-type optical network (Utility Model Registration No. 0205490) is fixed to two adjacent two optical cables 402 by a grating 401 at a hole lattice point, and the hole size is usually the length of a chest of an adult man It is about (85cm) long. If the intruder with a chest length of 95cm is forcibly opened and passed through the beam, it is essential that the beam is cut and detected without opening. According to the conventional optical guard system (Patent No. 12736), the optical network must be cut in order for the optical guard system to detect an intrusion and succeed in the alarm.
The optical network fabricated using the conventional single-core optical cable of FIG. 3 has a lattice 401 between the outer cladding 101 of the two adjacent optical cables 402 at the lattice 401 when the intruder tries to open the hole by force. Although fixed together, the outer sheath layer 101 of the four-sided optical cable 402 forming the optical fiber hole is stretched and the inner stiffener layer 102 and the optical fiber buffer layer 103 are pushed away from the grating 401. Even if the optical fiber hole is larger than the size of the intruder body, the optical cable 402 is not cut and a defect that does not detect the passage of the intruder is generated.

본 고안이 이루고자 하는 기술적 과제는 도3의 종래 1심 광 케이블과 동일한 재료를 사용하되 종래 1심 광 케이블을 사용하여 광망을 제작하였을 경우 발생되는 앞서 결함을 해소하여, 침입자가 광망을 절단할 때 뿐만아니라 광망 구멍을 억지로 벌리고 통과할 때도 감지하도록 하는 광망용 침입 감지 광 케이블을 제공하는 것이다.     The technical problem to be achieved by the present invention is to use the same material as the conventional single-core optical cable of Figure 3, but eliminates the defects that occur when the optical network is manufactured using the conventional single-core optical cable, when the intruder cuts the optical network In addition, the present invention provides an intrusion detection optical cable for an optical network that detects when the optical hole is forced through a hole.

본 고안의 광 케이블에서 광섬유 버퍼(Buffer)층(103)과 직접 밀착된 외피층(101) 바탕에 보강재(105)가 분산되어 박힌 2층 구조를 하며, 실제 광망의 제작을 위하여 사용시 도1에서와 같이 광섬유 버퍼(Buffer)층(103)과 직접 밀착된 외피층(101)바탕에 보강재(105)가 광섬유버퍼(Buffer)층(103)을 중심으로 동심원(103)상에 분산되어 박힌 구조를 하거나, 도2에서와 같이 광섬유 버퍼(Buffer)층(103)과 직접 밀착된 외피층(101)바탕에 보강재(105)가 광섬유 버퍼(Buffer)층(103)을 중심으로 비 동심원상에 분산되어 박힌 구조로 제작될 수있다.
본 고안의 광 케이블의 실시 가능 일반적 규격은 외피층의 굵기 3mm, 광섬유 버퍼(Buffer)층(103) 0.9mm, 보강재의 파단 인장력 10kg정도이고, 실제 빛의 전송로 기능을 하는 광섬유의 굵기는 0.125mm이다. 본 고안의 광케이블의 광섬유 버퍼(Buffer)층(103)과 광섬유(104)는 종래 1심 광 케이블의 그것들과 동일하다
도3의 종래 1심 광케이블의 3층 구조로 하는 경우에 비하여 외피층(101)과 보강재(105)간의 접착력이 현저히 증가되어 이를 사용하여 제작된 광망을 침입자가 억지로 망 구멍을 벌릴 때 광망 구멍 4변을 이루는 광 케이블(402)들에 가해진 인장력이 격자쇠(401)에서 외피층(101)으로 하여금 밀리도록 작용하지 아니하고 보강재(105)에 그대로 전달된다. 계속해서 힘을 증가 시키며 광망 구멍을 벌리게 되면 광망 구멍 4변을 이루는 광 케이블(402)의 외피층(101), 보강재(105)및 광섬유 버퍼(Buffer)층(104)이 모두 함께 늘어나기 시작하다가 파단 인장력(10kg)초과시 보강재(105)와 함께 광섬유 버퍼(Buffer)층(104)도 절단되어 마침내 감지하기에 이른다. In the optical cable of the present invention, the reinforcing material 105 is dispersed and embedded on the outer skin layer 101 directly contacted with the optical fiber buffer layer 103, and has a two-layer structure. The reinforcing material 105 is dispersed on the concentric circle 103 around the optical fiber buffer layer 103 on the basis of the outer skin layer 101 which is in close contact with the optical fiber buffer layer 103 as described above. As shown in FIG. 2, the reinforcing material 105 is dispersed in a concentric circle around the optical fiber buffer layer 103 based on the outer skin layer 101 which is in direct contact with the optical fiber buffer layer 103. Can be made.
The general standard of the optical cable of the present invention is 3mm thick of the outer layer, 0.9mm of the optical fiber buffer layer 103, and 10kg of tensile strength of the stiffener, and the thickness of the optical fiber functioning as the actual light transmission is 0.125mm. to be. The optical fiber buffer layer 103 and the optical fiber 104 of the optical cable of the present invention are the same as those of the conventional single-core optical cable.
Compared to the three-layer structure of the conventional single-core optical cable of FIG. 3, the adhesive force between the outer covering layer 101 and the reinforcing member 105 is significantly increased, and when the intruder forcibly opens the mesh hole using the optical network fabricated using this, four sides of the optical network hole The tensile force applied to the optical cables 402 constituting the optical cable 402 is transmitted to the reinforcement 105 as it does not act to force the outer skin layer 101 in the grating 401. As the force increases and the optical fiber hole is opened, the outer skin layer 101, the reinforcing material 105, and the optical fiber buffer layer 104 of the optical cable 402 forming the optical fiber hole 4 sides all start to stretch together and then break. In addition to the reinforcement 105 when the tensile force (10kg) is exceeded, the optical fiber buffer layer 104 is also cut to finally detect.

본 고안의 광케이블을 사용하여 제작된 광망을 침입자가 절단할 때 뿐만아니라 억지로 벌리고 통과할 때에도 감지하게 하는 효과가 있다.There is an effect to detect when the intruder as well as forcibly opens and passes through the optical network fabricated using the optical cable of the present invention.
