Frequently Asked Questions
What is 400GBASE-LR4 and why does it matter?
400GBASE-LR4 is an IEEE standard for 400Gb/s optical transmission over long-reach single-mode fiber. The LR4 designation indicates 10km capability, making it ideal for connecting data centers across campuses or linking geographically distributed network nodes without signal degradation.
Is this QSFP-DD transceiver compatible with my Mellanox infrastructure?
Yes. This ENET module is specifically designed as Mellanox-compatible, ensuring plug-and-play operation with Mellanox switches and network equipment. Verify your switch supports QSFP-DD ports and 400GBASE-LR4 protocols before deployment.
What does DOM monitoring provide?
Digital Optical Monitoring (DOM) enables real-time visibility into transceiver health metrics including optical power levels, temperature, and voltage. This 400GBASE-LR4 transceiver's DOM capability allows proactive network management and faster troubleshooting of connectivity issues.
Can I use this 10km transceiver for shorter distances?
Absolutely. The 400GBASE-LR4 module operates reliably at distances shorter than 10km. Many deployments use long-reach transceivers for flexibility and future-proofing, even when immediate link distances are shorter.
