Lesson 9: OSP Fiber Optic Network Design

How are fiber optic networks designed?
Objectives: From this lesson you should learn:
What Is Fiber Optic Network Design?
What is involved in fiber optic network design
What a designer needs to know
How an OSP project develops from idea to installation
How to choose equipment and components for the network
How to create a loss budget for the design
How to plan for and complete an installation

This lesson will help you learn the process of designing a fiber optic network. Not everyone will ever design a fiber optic network, but understanding the process will make installing, testing and documenting a network easier. Fiber optic network design refers to the specialized processes leading to a successful installation and operation of a fiber optic network. It includes determining the type of communication system(s) which will be carried over the network, the geographic layout (premises, campus, outside plant (OSP, etc.), the transmission equipment required and the fiber network over which it will operate. Designing a fiber optic network usually also requires interfacing to other networks which may be connected over copper cabling and wireless.

Next to consider are requirements for permits, easements, permissions and inspections. Once we get to that stage, we can consider actual component selection, placement (underground, direct buried, aerial or underwater), installation practices, testing, troubleshooting and network equipment installation and startup. Finally, we have to consider documentation, maintenance and planning for restoration in event of a future outage. The design of the network must precede not only the installation itself, but it must be completed to estimate the cost of the project and, for the contractor, bid on the job. Design not only affects the technical aspects of the installation, but the business aspects also.
