QDD-400G-SR8-S Cisco Compatible 400GBASE-SR8 QSFP-DD PAM4 Transceiver - 100m
Warranty: Lifetime
Cisco QDD-400G-SR8-S Compatible 400GBASE-SR8 QSFP-DD PAM4 Optical Transceiver - 100m Reach
This third-party QSFP-DD optical transceiver is fully compatible with Cisco QDD-400G-SR8-S, delivering 400Gbps Ethernet over parallel multimode fiber (MMF) up to 100 meters. Perfect for short-reach, high-density connections in AI/HPC GPU clusters, hyperscale data centers, and spine-leaf architectures where low cost and power efficiency are key.
Built to MSA standards with 8x50G PAM4 parallel lanes, it features an MPO-16 connector and digital diagnostics (DOM). Backed by our lifetime warranty and rigorous testing—get 70-90% savings vs. genuine Cisco OEM with proven reliability.
Key Features
- Massive Cost Savings: Premium compatible optics—scale dense AI networks affordably.
- Plug-and-Play: Hot-pluggable QSFP-DD form factor with pre-programmed EEPROM for seamless Cisco compatibility.
- Short-Reach Efficiency: 100m over OM4/OM5 MMF—ideal for intra-rack or row-level GPU interconnects.
- Lifetime Warranty: Fully tested with certification reports; same-day shipping available.
- Use Cases: High-bandwidth links in NVIDIA H100/B200 clusters, data center top-of-rack switches, or multi-node training fabrics.
Technical Specifications
- Data Rate: 400Gbps (400GBASE-SR8, 8x53.125Gbps PAM4)
- Wavelength: 850nm
- Connector: MPO-16 (parallel MMF)
- Reach: Up to 100 meters on OM4/OM5 multimode fiber (70m on OM3)
- Power Consumption: ≤12W
- Operating Temperature: 0°C to 70°C
- Standards Compliance: IEEE 802.3bs, QSFP-DD MSA, CMIS 4.0, RoHS
- Features: Digital Optical Monitoring (DOM/DDM) support
Compatibility
Programmed for full compatibility with Cisco platforms and MSA-compliant systems, including:
- Cisco Nexus 9000/3000 series (400G ports)
- Cisco ACI and data center switches
- Arista 7800R/7500R series
- NVIDIA/Mellanox Quantum-2 (in Ethernet mode)
- Other QSFP-DD 400G platforms (Juniper, Broadcom-based)
