Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of optical fiber patch cord, concretely to a multi-interface optical fiber patch cord. BACKGROUND

[0002] Optical fiber patch cord refers to the connector plug on both ends of the optical cable, which is used to realize the active connection of the optical path. The end with the plug is called the tail fiber. The optical fiber patch cord is similar to the coaxial cable, but it does not have a mesh shielding layer. The center is a glass core for light transmission. In a multimode optical fiber, the diameter of the core is 50 to 65 microns, which is roughly equivalent to the thickness of a human hair. The diameter of the single-mode optical fiber core is 8 to 10 microns. Outside the core is a layer of glass envelope with a lower refractive index than the core, which keeps the optical fiber in the core. Outside is a thin plastic jacket to protect the envelope.

[0003] In order to facilitate the arrangement of the optical fiber patch cord in the weak current box, branch patch cords are used. The main line of the optical fiber is provided with multiple branch lines at one end, which can simultaneously connect multiple interfaces. One main line of the optical fiber may connect 12 or more branch lines. The diameter of the optical fiber branch line is much smaller than that of the main line. The branch line has high flexibility and is easy to entangle with each other, causing difficulty in arrangement. Therefore, we propose a multi-interface optical fiber patch cord.
