| Abstract: | The link gain and noise figure(NF) models for long-haul optical transmissions were established.Then the relationships between link gain,NF and the bias voltage of Mach-zehnder modulator were analyzed.And the effects of dispersion on the link gain were calculated.The functional relationship of relative intensity noise,shot noise,and EDFA noise with NF was deduced and analyzed.The link gain and NF were improved by optimizing the bias voltage of the modulator. |

| Keywords: | relative intensity noise fiber-optical links link gain noise figure |
