Problems solved by technology

With the optical fiber attenuator of this structure, when adjusting the distance of the microbending deformer, an adjuster is required, that is, adjusting the adjuster to make the microbending deformer move along the sliding guide rail to adjust the distance. According to the actual use, it can be The adjuster is realized by manual, motor, voltage, magnetic field, etc. When the manual method is used, the adjustment rod of the connector is provided with threads, and the adjustment of the distance of the micro-deformer is realized by rotating the adjustment rod, which is very troublesome to operate

Abstract

The invention discloses an easily-adjustable optical fiber attenuator which comprises an optical fiber and a microbend deformer for adjusting the curvature of the optical fiber. The microbend deformer comprises a casing, wherein a groove is formed in the casing, the optical fiber is positioned in the groove, an upper press plate is arranged on the optical fiber, lower corrugations are arranged at the bottom of the groove, and upper corrugations staggered with the lower corrugations are arranged on the lower surface of the upper press plate. Slide guide rails respectively arranged on the two lateral walls of the groove are not parallel to the bottom of the groove, an adjustment cylinder is movably arranged in the slide guide rails, an n-shaped press balance frame is arranged on the upper press plate, an opening of the press balance frame is upward, and the adjustment cylinder is positioned in the press balance frame. The easily-adjustable optical fiber attenuator is simple in structure, easy to operate and capable of being adjusted manually and easily.

Description

technical field [0001] The invention relates to the field of optical fiber attenuators, in particular to an easily adjustable optical fiber attenuator. Background technique [0002] Optical fiber attenuators are passive components widely used in the field of optical communications. It is used to attenuate the input optical power, avoiding the distortion of the optical receiver due to the super strong input optical power. In order to achieve continuous adjustment, the existing optical fiber attenuator adopts a structure with the publication number CN 1658023 A, which uses a micro-bend deformer to realize the bending degree of the optical fiber, so as to realize the modulation of the signal light intensity in the optical fiber, so as to realize Adjustable light attenuation. With the optical fiber attenuator of this structure, when adjusting the distance of the microbending deformer, an adjuster is required, that is, adjusting the adjuster to make the microbending deformer mo...
