54 //Interface receive optical powerIf an optical module on an interface is faulty, you can run the display commands to view information about the optical module. During use, reading optical module information helps understand its real-time operating status, enabling faster troubleshooting of link abnormalities. Industry pundits have recently speculated that demand for 100G/400G switches may take off in 2019, prompting optical transceiver module vendors to sample data center switches with high data transmission rates earlier than expected. 00 // optical module receiving power alarm limit RX Power Low Threshold (dBM): - 16.
