Butterfly-shaped optical cable jump fiber

Abstract

The invention relates to a butterfly-shaped optical cable jump fiber. Two ends of a single-core butterfly-shaped optical cable are provided with connectors with the same structure. Each connector is structurally characterized in that the single-core butterfly-shaped optical cable is connected with a back end of a metal tail handle, and the front end of the metal tail handle is connected with the back end of a ceramic insertion core after being sleeved with an SC (square connector) main body and a spring; an optical fiber fibril and a blue core wire which are covered by a stiffener penetrate through a centre hole of the metal tail handle, the optical fiber fibril is connected with the ceramic insertion core; a joint of the single-core butterfly-shaped optical cable and the metal tail handle is in protective fixed connection by an aluminum riveting component, and the joint is sleeved with a plastic sheath; the SC main body is connected with the back end of a plastic inner frame in an embedding mode, so that a connection head which consists of the ceramic insertion core, the metal tail handle, the aluminum riveting component and the single-core butterfly-shaped optical cable is movable relative to the plastic inner frame. The butterfly-shaped optical cable jump fiber disclosed by the invention has the advantages that a hard optical fiber is used as the jump fiber, the optical fiber fibril is protected more effectively, threading and connection are convenient, bending is not overlarge, signals can not be attenuated, and a ready-mad jump fiber is provided for the last section of FTTH (fiber to the home).

Description

technical field [0001] The invention relates to the technical field of optical fiber communication equipment, in particular, it is a hard optical cable used in optical fiber to the home (FTTH) -- a butterfly optical cable jumper. Background technique [0002] The application of optical fiber technology in our country has been very common. Fiber to the home (FTTH) is one of the most efficient measures in optical fiber application at present, and it requires the use of many optical fiber distribution equipment and components. After the implementation of fiber-to-the-home, the household broadband access capacity can exceed 100 megabits per second, and the effect of its application is very obvious. [0003] Connecting the outdoor optical cable to each household in the residential area has to go through a series of optical fiber distribution and connection. At present, floor distribution boxes are often used in cities or places where the population is concentrated. In the process...

Problems solved by technology

However, since the soft optical cable is composed of the outer sheath (sheath), aromatic wheel, white core wire and optical fiber wire, the jumper made of soft optical fiber (see attached figure 1 ) are prone to problems: ①Because the wire body is too soft, sometimes it is inconvenient to wear and connect when doing engineering, especially when it is worn from bottom to top; ②The soft optical cable is easily affected by external factors (people, environment), and it is easy to cause
