Many high-speed serial interface standards call for a test known as 'Stressed Eye. In high-speed networks, an eye diagram optical transceiver can reveal whether your link is healthy before users ever report packet loss. This article helps network engineers and field technicians interpret eye metrics, compare common transceiver options, and diagnose failures using repeatable lab.
