摘要： When planning and maintaining a network, it may be very difficult for a network provider to organize variations of equipment rack installations at several different sites. Present methods of planning installation configurations in a network involve planning the same equipment installation configuration at all sites, planning a limited number of variations, or planning multiple variations but, with difficulty, tracking and changing configurations. A method or corresponding apparatus in an example embodiment of the present invention provides a tool for simplifying the planning of multiple network element installation configurations at multiple sites within a network. The benefits include fewer required truck rolls, resulting in reduced costs before and after deployment of installation configurations. In one embodiment, the disclosed planning tool allows users to access and change generic installation configurations according to customizable options to allow users to produce and store customized templates of multiple network element installation configurations.

摘要： The disclosed methods and apparatuses provide a unique and cost efficient approach to using traffic channels of an optical mesh network, and sometimes optical supervisory channels, for carrying timing information (e.g., BITS timing signals), thus eliminating the need to use external BITS sources at remote add/drop nodes of a network. Planning the distribution of timing in such an optical mesh network includes identifying in the network a source node associated with an external timing source, identifying optical light paths between nodes in the network, and, for nodes other than the source node, selecting optical light paths originating either directly or indirectly from the source node to use to derive timing information.

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。
