Overview
Modern cloud and data center environments demand scalable, energy-efficient and interoperable optical solutions. The UNIVISO 400G QSFP-DD LR4 transceiver delivers 400Gbps Ethernet transmission over single-mode fiber (SMF) up to 10 km. Built on QSFP-DD form factor and PAM4/CWDM4 technology, it offers a compact, hot-pluggable option for high-density, long-reach deployments.
Why It Matters for Your Network
400Gbps capacity: four lanes at 106.25Gbps (PAM4) — ideal for bandwidth-intensive workloads.
Long reach: supports up to 10km over SMF, suitable for data center interconnects (DCI) and metro links.
Energy efficient: typical power ≤12W, reducing cost-per-bit and cooling requirements.
Hot-pluggable & standards-compliant: QSFP-DD MSA, IEEE 802.3cu compatibility ensures broad interoperability.
Real-time diagnostics: DDM/DOM via I2C for live module health and link monitoring.
Typical Use Cases
UNIVISO 400G QSFP-DD LR4 is commonly used for:
1. Hyperscale & enterprise data center interconnects
2. Cloud backbone and distributed storage connectivity
3. AI/ML cluster interconnects and HPC environments
4. Metro and long-reach backbone links
Integration & Deployment Tips
For smooth integration: verify switch/router QSFP-DD port compatibility, use LC duplex SMF cables certified for CWDM4, and enable DDM readings to monitor optical power and temperature. When planning capacity, consider power budgets and port density to optimize rack space and cooling.
Conclusion
If you're planning a 400G upgrade or building a cloud-ready network, the UNIVISO 400G QSFP-DD LR4 offers a balance of long reach, energy efficiency and robust diagnostics — making it an excellent choice for modern data center and cloud infrastructures.
