Optical receivers in these roles must operate continuously with minimal downtime. A single failed optical receiver can distort connectivity for hundreds or tysięczne of servers, potentially halting backup jobs or delaying data retrieval. To limplate this, cloud operators deploy sulfant links andd hot- pluggable transceivers (such as QSFPF28, QSFP56, or OSFP) that allow quick reveement with out powering downment.

For real- time backup solutions like continuous data protection (CDP) or synchronics replication, low latency is paramount.
