摘要： Information about optical amplifier ASE power is propagated down a link. Each amplifier along the link can learn of the ASE power at its input and take this input ASE power into account in controlling its own per channel output power. Each amplifier can also pass along to the next amplifier an indicator that represents its output ASE power taking into account both its input ASE power and own generated ASE power. Intermediate optical add/drop multiplexers (OADMs) adjust the ASE power indicator to account for losses and the spectral characteristics of each filter.

摘要： Systems and methods for upgrading selected wavelengths in a WDM link to higher data rates at minimal expense are provided. Error correction coding techniques are employed such that the data encoded onto the upgraded wavelengths experiences higher coding gain than that experienced by data encoded on the non-upgraded wavelengths. This increases receiver sensitivity without the use of expensive opto-electronic components. In one embodiment, Reed-Solomon coding is employed on the upgraded wavelengths and no error correction coding is employed on the remaining wavelengths. These techniques may also be applied to new WDM links carrying channels with disparate bit rates.
摘要翻译：提供了以最小的费用将WDM链路中的选定波长升级到更高数据速率的系统和方法。使用错误校正编码技术，使得编码到升级波长上的数据经历比在非升级波长上编码的数据经历的编码增益更高的编码增益。这增加了接收机灵敏度，而不使用昂贵的光电组件。在一个实施例中，Reed-Solomon编码被用于升级后的波长，并且在其余波长上不采用纠错编码。这些技术也可以应用于携带具有不同比特率的信道的新的WDM链路。
