QDD-400G-DR4-S Cisco Compatible 400GBASE-DR4 QSFP-DD PAM4 Transceiver - 500m
Warranty: Lifetime
Cisco QDD-400G-DR4-S Compatible 400GBASE-DR4 QSFP-DD PAM4 Optical Transceiver - 500m Reach
This third-party QSFP-DD optical transceiver is fully compatible with Cisco QDD-400G-DR4-S, delivering 400Gbps Ethernet over parallel single-mode fiber (SMF) up to 500 meters. Ideal for high-bandwidth data center interconnects, AI/HPC spine-leaf architectures, and hyperscale networks requiring longer reaches beyond copper/DAC limits.
Built to MSA standards with 4x100G PAM4 modulation, it features an MPO-12/APC connector and digital diagnostics (DOM). Backed by our lifetime warranty and rigorous testing—enjoy 70-90% savings vs. genuine Cisco OEM while ensuring reliable, high-performance optics.
Key Features
- Massive Cost Savings: Premium compatible optics at refurbished/third-party pricing—scale AI and data center networks affordably.
- Plug-and-Play: Hot-pluggable QSFP-DD form factor with pre-programmed EEPROM for seamless Cisco compatibility.
- Extended Reach: 500m over parallel SMF—perfect complement to short-reach SR8 or DACs.
- Lifetime Warranty: Fully tested with certification reports; same-day shipping available.
- Use Cases: Spine-leaf links in large AI clusters, data center interconnections (DCI), or high-throughput storage fabrics.
Technical Specifications
- Data Rate: 400Gbps (400GBASE-DR4, 4x106.25Gbps PAM4)
- Wavelength: 1310nm
- Connector: MPO-12/APC (parallel SMF)
- Reach: Up to 500 meters on single-mode fiber
- 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)
