Product FAQ

Frequently Asked Questions

Answers to common compatibility, installation and troubleshooting questions.

Why does my switch detect the transceiver but not establish a link?

Possible causes include incorrect fiber type, wavelength mismatch, polarity, dirty connectors, excessive optical loss, incompatible link partners, FEC settings, port configuration, or compatibility issues.

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.

Can different transceiver brands be used at opposite ends of a fiber link?

Yes. The transceivers do not normally need to be from the same manufacturer. Their Ethernet standard, wavelength, fiber type, lane configuration, reach, and other link requirements must be compatible.

Can compatible transceivers be used for 100G, 400G, and 800G networks?

Yes. Compatible modules are available across many high-speed interfaces, although compatibility requirements become increasingly platform-specific at higher data rates.

Are compatible transceivers suitable for enterprise networks?

Yes. They can be used in enterprise switching, routing, storage, campus networks, and other applications when properly matched to the network equipment and link requirements.
