Embodiment Construction

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] Such as figure 1 and figure 2 As shown, an optical fiber jumper with a spring protective layer includes an optical cable 2 and connectors 1 arranged at both ends of the optical cable 2. The optical cable 2 includes an outer protective layer and a glass core 21 for light transmission inside. The outer protective layer is from the inside to the The outside includes a glass envelope 22 and an insulating rubber layer 25. A spring protection layer 24 is also provided between the glass envelope 22 and the insulating rubber layer 25. The gap between the spring protection layer 24 and the glass envelope 21 and the insulating rubber layer 25 is filled with Sponge 23, the two ends of the spring in the spring protective layer 24 are respectively fixed on the two connectors 1, so as to improve the radial compression resistance of the jumper.

Abstract

The invention discloses an optical fiber jumper with a spring protection layer, comprising an optical cable and connectors arranged at the two ends of the optical cable. The optical cable comprises an external protection layer and an internal glass fiber core for light propagation. The external protection layer comprises a glass sealing sleeve and an insulating rubber layer from inside to outside, and a spring protection layer is arranged between the glass sealing sleeve and the insulating rubber layer. The gap between the spring protection layer and the glass sealing sleeve and the gap between the spring protection layer and the insulating rubber layer are filled with sponge. The two ends of a spring in the spring protection layer are respectively fixed to the two connectors. By arranging the spring protection layer in the external protection layer of the glass fiber core, the radial compressive ability of the jumper is improved, the glass fiber core is prevented from being bent too much and damaged, and the overall strength of the jumper is greatly improved.

Description

technical field [0001] The invention relates to the technical field of photoelectric communication equipment, in particular to an optical fiber jumper with a spring protective layer. Background technique [0002] Fiber optic jumpers are used as jumpers from equipment to fiber optic cabling links. It has a thicker protective layer and is generally used for the connection between the optical transceiver and the terminal box. Optical fiber jumper means that both ends of the optical cable are equipped with connector plugs to realize the active connection of the optical path, and one end with a plug is called a pigtail. [0003] Existing fiber optic jumpers are similar to coaxial cables, but without the mesh shield. In the center is the glass core for light propagation. The fiber core is surrounded by a glass jacket with a lower refractive index than the core to keep the fiber inside the core. On the outside is a thin plastic jacket to protect the envelope. The existing opti...
