Final answer:
A link loss budget is required during the design phase of a cable plant installation to predict and compare the costs associated with different installation options. Mathematical models help relate technique science to financial feasibility, with costs often normalized for comparison on a per-unit basis.
Step-by-step explanation:
A link loss budget should be done for every cable plant installation during the design phase of a project. During this phase, mathematical models are particularly useful as they aid in estimating costs for the different approaches under consideration. These models can predict costs for various alternative solutions that might be identified during the idea generation phase.
Furthermore, by understanding the science behind a technique, and applying the mathematical models, one can establish the relationship between the technical intricacies and the financial implications of installation, fabrication, operation, and maintenance. To facilitate comparisons between different options, these costs are normalized to a standard measure, often cost per thousand gallons of water for projects involving water management.
In essence, these calculations and models ensure that decision-makers can evaluate the feasibility and sustainability of each option regarding both technical and financial perspectives during the critical design phase of the installation process.
