For example, you want to transmission 100G from Site A to site B.
There are 2 routings, you only choose routing 1, If the optical cable is broken, the transmission is interrupted.

You choose 2 routings, add OLP,  Routing 1 is primary link , and routing 2 is secondary link, If the optical cable is broken, the transmission will automatically jump from the primary link to the secondary link. Ensure uninterrupted business
