Description

蝶形光缆跳纤 Butterfly jump fiber optic cable

技术领域 FIELD

[0001] 本发明涉及光纤通讯设备技术领域,具体的说,是一种在光纤到户(FTTH)中使用的硬光缆——蝶形光缆跳纤。 [0001] The present invention relates to the field of optical fiber communication technology equipment, specifically, the cable is hard for use in fiber to the home (FTTH) - the butterfly fiber jumper cable.

背景技术 Background technique

[0002] 光纤技术在我国的应用已经非常普遍,光纤到户(FTTH)是目前光纤应用中效率最好的措施之一,它需要使用许多光纤分配设备和部件。 [0002] application of fiber technology in China has been very common, fiber to the home (FTTH) is one of the best measures currently in fiber applications efficiency, it needs to use a lot of fiber distribution equipment and components. 实现光纤到户后,家庭宽带接入能力可超过每秒100兆比特,其应用的效果是非常明显的。 After achieve fiber to the home, home broadband access capability over 100 megabits per second, the effect is very obvious application.

[0003] 将室外光缆接通到住宅小区的每户居民家中要经过一系列的光纤分配和接续,目前,在城市或人口集中居住的地方多采用楼层配线箱来实现,在光纤到户过程中要使用到大量的尾纤和跳纤。 [0003] The outdoor fiber optic cable turned into residential area of ​​household residents of the home through a series of fiber distribution and connection, at present, or in the city where people live together use more floor wiring boxes to achieve, fiber to the home in the process to be used in a large number of fiber pigtails and jump. 从到户的光纤终端到具体的设备之间还是要用光纤连接的,即,在用户家中也还有光纤接续的需求。 The fiber optic terminal from the home to the particular apparatus or use between the optical fiber connection, i.e., in the user's home there is also demand optical fiber connector. 对此,目前采用的方法是,用软光缆接上接头做成跳纤进行使用。 In this regard, the method currently used is made of soft fiber jumper cable connected to the connector for use. 但是,由于软光缆是由光缆外披覆(护套)、芳轮、白色芯线和光纤丝构成的,用软光纤做成的跳纤(见附图1)容易产生的问题是:①因线体太软在做工程时有时穿接不方便,尤其是由下往上穿时;②软光缆容易受外界因素(人、环境)的影响,容易造成弯曲半径小,导致信号的衰减;③由于白色芯线与光缆外披覆之间设置的是凯夫拉材料,之间有一定的间隙,因此,白色芯线在光缆外披覆内是可以活动的,或者说,光缆外披覆相对于光纤丝是有收缩性的,由于收缩性的存在,有时会对连接固定后的光纤丝保护不够。 However, since the cable is a flexible cable outer cladding (sheath), aryl wheel, white core and composed of silk fibers, optical fibers made of the problem with a soft fiber jumper (see FIG. 1) is likely to occur are: ① by line body is too soft and sometimes inconvenient to wear contact in doing the project, especially when worn by the bottom-up; ② soft cable susceptible to external factors (people, environment), likely to cause a small bend radius and cause signal attenuation; ③ Since the core wire is provided between the white and the outer cladding of the cable is Kevlar material, there is a certain gap between, and therefore, the white wire cable in the outer cladding is active, or that the outer cladding relative to the cable the fiber filaments are contractile, due to shrinkage, the optical fiber may be connected to the wire fixing insufficient protection.
