Optical fiber dispersion compensation method and its device

Abstract

The fibre dispersion compensation equipment includes dispersion compensation module, and includes a three-port irreversible optical device and an optical reflector device. Said three-port irreversible optical device, dispersion compensation module and ptical reflector device are sequentially connected, the optical signal is fed into first port of the above-mentioned three-port irrevesible opticaldevice, and outputted from second port and fed into dispersion compensation module to make dispersion compensation, then reflected by optical reflector device and fed into dispersion compensation module again to make secondary dispersion compensation, then said optical signal is fed into second port, and is outputted from third port, and fed into the dispersion compensation module, so that it cangreatly raise utilization rate of dispersion compensation optical fibre.

AI Technical Summary

Benefits of technology

The technology described in this patented solution improves how well an interference filter works when transmitting signals through different media without affecting their quality or reliability. It uses dispersive compensations that allow light waves from one medium enter another while being reflected off other surfaces before reaching its destination. This allows more efficient use of fibers and reduces costs associated therewith. Additionally, combining these techniques together helps reduce distortion caused during communication due to differences between materials used at each location.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency at transmitting light signals over long distances without requiring expensive equipment or complicated process steps for achieving desired properties such as improved bending loss characteristics due to reduced polarisation mode disperity.
