Digital-to-analog converter for optical fiber communication

Abstract

The invention relates to the technical field of optical fiber communication, and discloses a digital-to-analog converter for optical fiber communication. The digital-to-analog converter comprises a shell, a laser is fixedly connected with the inner wall of the left side of the shell, a polarizer is fixedly connected with the right side of the laser in the vertical direction of the shell, an iron core is arranged on the right side of the polarizer, a coil is wound on the outer side of the iron core, the right side of the iron core is fixedly connected with a polarization detection plate, the right side of the polarization detection plate is provided with a permanent magnet, and the right side of the permanent magnet is fixedly connected with a rotating box. Laser beams generated by the helium-neon laser device enter the iron core to deflect, then the permanent magnet is driven to deflect, finally periodic rotation of the rotating box is achieved, meanwhile, alternating current electric signals in the coil are converted into discrete digital signals through cooperative arrangement of a limiting block and a piezoelectric block, the effect of effectively reducing the load effect is achieved, and the problem of poor accuracy of discrete digital signals caused by the load effect during passband constant current work in the prior art is solved.
