Cannot Ping Over Lan Until A Ping Is Received

Customization process for high-precision optical power meter with 1m event dead zone for LAN

In response to the problems of low accuracy, high radiation, and high power consumption in industrial UV power detection, the author proposes a design scheme based on a low-power microcontroller M.

Ont optical module received optical power

Run the display interface transceiver verbose command to check the transmit and receive optical power of an optical module. SFP Detail Diagnostics Information (internal calibration) Current Alarms Warnings Measurement High Low. When the optical module on an interface is faulty, you can run the display commands to view information about the optical module.
