DCF: dispersion compensation board

DCF is the negative dispersion optical fiber launched by Sintai Communication Co., Ltd, which is a new kind of single mode optical fiber designed for current G.652& G.655standard single-mode optical fiber; the dispersion of G.652 optical fiber in the vicinity of 1550nm wavelength is positive (17-20) ps/nm (km), and the dispersion of G.655 standard optical fiber in the vicinity of 1550nm wavelength is positive (4-6) ps/nm (km), with a positive dispersion slope. So we need to add dispersion compensation fiber with negative dispersion into the optical fiber to carry out the dispersion compensation and make sure that the total dispersion of the whole optical fiber line is near zero. Thus high speed, large capacity and long distance communication can be realized.

Dispersion Compensation Principle

Dispersion is one of the transmission properties of optical fiber, and the optical pulse signal will be broadened in time after transmission in the fiber for a distance, which produces inter-symbol interference, thus increasing the error rate and affecting the quality of communication.

  •  The higher the data rate is, more easily the inter-symbol interference will occur

  •  The longer the transmission distance is, more easily the inter-symbol interference will occur
