By adopting the same wavelength of spread spectrum sequence, spectrum resources utilization, combining with WDM high, can be greatly increased system capacity. Spectrum and signal itself by the detuning is irrelevant to a coded to finish. Say spectrum characteristic of the detuning yards codes or keys, sometimes called address.

Among them, the dispersion characteristics of optical fiber transmission of will cause disturbance, namely before and after yards intersymbol interference, limiting the transmission code rate and the transmission distance. Aiming at the transmission lines laid the existing G652 single-mode optical fiber dispersion the bigger question, can will DCF model G652 optical fiber as dispersion compensation and dispersion slope compensation parts, components compensation type FRA. 职荣保 通信072班 Coherent light communication1.
