【 摘 要 】

In this paper, we provide overview of deployed wavelengths for long haul ultra-stable coherent frequency dissemination. Based on effort to eliminate noise caused by parallel data transmission, we are proposing to utilize the S band. Suitable ways of optical amplification are discussed, and the most promising Raman amplification is chosen for deeper investigation.
