摘要： This invention provides a method for commissioning and upgrading an optical ring network using its internal amplifiers as Automatic Spontaneous Emission sources of light that are used in making measurements. A modular segmented approach is adopted and the network is commissioned segment by segment. A flexible method is used for upgrading a commissioned network by adding or deleting a node or changing the internal configuration of a node. The method uses techniques for the correction of the Optical Signal to Noise Ratio induced error as well as the Spectral Filtering Error during the loss computation required for adjusting the gains of the amplifiers at each network node to an appropriate value. Since the method does not require an external laser source that needs to be moved manually from node to node it greatly reduces the commissioning time. Since it uses only the components of the network itself and does not deploy any additional device it also leads to a significant saving in cost.

摘要翻译： 本发明提供了一种使用其内部放大器调试和升级光环网络的方法，所述放大器是用于进行测量的自动自发发射光源。 采用模块化分段方式，逐段调试网络。 灵活的方法用于通过添加或删除节点或更改节点的内部配置来升级委托网络。 该方法使用用于校正光信噪比诱导误差的技术以及在将每个网络节点处的放大器的增益调整到适当值所需的损耗计算期间的光谱滤波误差。 由于该方法不需要需要从节点手动移动的外部激光源，因此大大减少了调试时间。 由于它仅使用网络组件本身，并且不部署任何其他设备，因此也可大大节省成本。
