What factor is critical when selecting fibers for an installation?

Selecting fibers for an installation hinges significantly on their compatibility with existing connectors. This compatibility ensures that the fibers can effectively interface with the hardware already in place, allowing for proper signaling and communication across the network. If the fibers do not match the specifications of the existing connectors, this can lead to issues such as increased insertion loss, reflections, and potential data transmission errors.

Other factors such as color coding, length, and weight may be relevant in specific contexts but do not have the same direct impact on the functionality and integration of an installation. Color coding assists with identification and organization but does not affect performance. The length of the fiber can influence the installation design and run distance, yet it does not impact compatibility with connectors. Similarly, while weight may be a consideration for certain physical installations, it does not directly correlate with the effectiveness of linking fibers to components. Thus, ensuring that fibers are compatible with existing connectors is paramount for a successful and efficient installation.
