摘要： Signals propagating in wavelength division multiplexing (WDM) optical networks suffer from loss, which decreases optical signal-to-noise ratios (OSNRs) and degrades a quality of received transmissions. Present methods of boosting OSNRs involve regeneration using transponders, which scale in complexity with the number of WDM channels. Optical amplifiers may boost signal strength, but amplified spontaneous emission (ASE) noise often reduces OSNR despite increases in signal strength, although changing the amplifier operating settings may reduce emitted ASE noise power. A method or corresponding apparatus in an example embodiment of the present invention provides a planning tool for deploying optical amplifiers in an optical network in a manner that reduces the need for optical regeneration, reducing cost and complexity of the deployed network. In one embodiment, the disclosed planning tool may substitute models of high-gain amplifiers operating at low settings for models of low-gain amplifiers operating at high settings.
摘要翻译：在波分复用（WDM）光网络中传播的信号遭受损失，这降低了光信噪比（OSNR），并降低了接收传输的质量。目前提升OSNR的方法涉及使用转发器的再生，这些应答器的复杂度随着WDM信道的数量而增加。光放大器可以提高信号强度，但放大的自发发射（ASE）噪声通常会降低OSNR，尽管信号强度有所增加，尽管改变放大器工作设置可能会降低发射的ASE噪声功率。在本发明的示例性实施例中的方法或相应的装置提供了一种用于在光网络中部署光放大器的规划工具，其方法是减少对光学再生的需要，降低部署网络的成本和复杂性。在一个实施例中，所公开的规划工具可替代以低设置操作的高增益放大器的模型，用于在高设置下工作的低增益放大器的模型。

摘要： An example embodiment of the invention includes a method and apparatus for supporting fiber span loss and dispersion measurements in the presence or absence of dispersion compensation elements (DCE). The technique may be used to configure a network link by accessing an optical signal at an ingress side of a connection point for a DCE coupling an egress side of a fiber span at the ingress side of the DCE to an optical amplifier at a connection point for an egress side of the DCE. The technique may include determining chromatic dispersion of the fiber span based on the optical signal and reporting information associated with chromatic dispersion. As a result, the technique may be used, for example, during initial system installation when user data signals and the DCE are not present as well as after the network begins carrying user traffic and after a DCE has been installed.
