TX Power (Transmit): The strength of light leaving the switch. Low RX is the most common cause of intermittent link issues. When designing optical networks, understanding the TX/RX power range is vital for ensuring optimal performance and long-term reliability. The TX (transmit) and RX (receive) power levels significantly affect everything from signal strength to transmission distances and the overall optical power. For network engineers working with fiber optics (SFP, SFP+, QSFP), understanding TX (Transmit) and RX (Receive) signal strength is critical. Receive power is normally expected between - 1 and -9. DOM is supported on MS120, MS125, MS130, MS150. This article is intended to assist with the interpretation of the SFP transceiver TX and RX power readings available from the CLI.
