Fire cable trays can be used to store fiber optic cables
These cables are used exclusively within buildings and must have a flame-retardant jacket to fit this purpose. They may be deployed in duct (conduit) or cable tray. Different environments. Fire-resistant cable trays that support electrical and communication cables in hospitals must be made of fire-resistant materials to ensure uninterrupted operations during emergencies. In these high-risk areas, the correct material choice can be a matter of life and death. When routing a cable within a building, you will also need to factor in fire prevention. Fiber cable trays isolate jumpers from other cables, support multi-directional routing of jumpers, protect jumpers from physical damage while ensuring their bending radius, and provide storage for redundant jumpers.
