Alternate trunks

Optical fiber allows much greater distances between devices than copper bus-and-tag cables. For this reason, link availability can be affected by more external factors, such as construction activities, extremes in temperature, and natural disasters. All trunk cable routing should therefore be reviewed for possibilities of interruption. If these interruptions can cause a critical situation, consider installing physically separate trunks. If one trunk becomes damaged, the other trunk can then be used to minimize interruption time.
