Q
How can I verify that the transceiver is functioning correctly?
A
Check the host port LED for a steady link light and use CLI commands (e.g., show interfaces transceiver diagnostics) to confirm signal levels and DOM data.
Q
What is the difference between BX-D and BX-U transceiver modules?
A
BX-D modules (downstream) transmit at 1490 nm and receive at 1310 nm; BX-U modules (upstream) reverse those wavelengths to complete a bidirectional link.
Q
Does the HP X122 1G SFP LC BX-D support digital optical monitoring (DOM)?
A
Yes. It includes digital optical monitoring to report real-time parameters such as TX/RX power, temperature and supply voltage via the host interface.
