What information should always be included in fiber-optic network documentation?

Including fiber assignments in fiber-optic network documentation is crucial because it provides a clear and organized mapping of how fibers are allocated within the network. Fiber assignments detail which fibers are designated for specific connections, how they are routed, and what devices they link to. This knowledge is essential for troubleshooting, maintenance, and future expansions or modifications to the network. It facilitates easier identification of issues and contributes to efficient management of the network.

While the other options—maintenance schedules, contact information, and material specifications—contribute to effective network management and support, they do not specifically address the immediate needs for clarity in allocation and tracking of fiber connections, which is vital in a fiber-optic network.
