Frequently Asked Questions

Answers to common compatibility, installation and troubleshooting questions.

Why does my compatible transceiver show low RX optical power?

Low receive power can result from excessive fiber loss, dirty connectors, damaged fiber, excessive link distance, incorrect wavelength pairing, or insufficient transmit power from the remote transceiver. Compare the measured RX power with the module's specified receiver range.

What information does DDM/DOM provide?

DDM/DOM can provide real-time information such as module temperature, supply voltage, transmit optical power, receive optical power, and laser bias current.

Do compatible transceivers support hot swapping?

Most SFP-family, QSFP-family, and similar pluggable transceivers are designed for hot-pluggable operation according to the applicable interface specification. Host-equipment procedures should still be followed.

Why does a high-speed compatible transceiver show FEC errors?

FEC errors may result from incompatible FEC settings, excessive optical loss, signal-quality problems, incorrect fiber infrastructure, or incompatible link parameters. Verify that both ends use the required FEC mode for the interface.

Why is EEPROM programming important for compatibility?

Network equipment may inspect the module's EEPROM information before allowing normal operation. Correct programming helps the host identify and manage the transceiver properly.
