Scrambling the polarisation of wavelength division multiplexed signals |
摘要 |
A method and apparatus for scrambling the polarization of signal lights combined into a wavelength division multiplexed signal light, to suppress non-linear optical effect and thereby improve transmission quality. For example, each signal light has a different polarization before being combined into a wavelength division multiplexed signal light. The polarization of the wavelength division multiplexed signal light can then be scrambled. Alternatively, the polarization of each signal light can be scrambled at a different scrambling frequency before being combined into the wavelength division multiplexed signal light.
