The Huawei QSFP-DD-400G-SR4 is a high-performance, hot-pluggable optical transceiver designed for 400 Gigabit Ethernet links over multi-mode fiber (MMF). Utilizing the QSFP-DD (Quad Small Form-factor Pluggable Double Density) form factor, it leverages 8 channels of 50G PAM4 modulation to deliver a massive aggregate bandwidth of 400Gbps. This module is the cornerstone for modern high-density networking environments.

Q: What are the primary applications of the Huawei QSFP-DD-400G-SR4? A: This module is engineered for short-reach high-bandwidth connections. Key applications include Data Center Interconnects (DCI), High-Performance Computing (HPC) clusters for AI training, and leaf-spine architecture in cloud networks where high density and low latency are critical.
Q: How does 400G SR4 compare to 400G DR4? A: The main difference lies in the transmission medium and distance. 400G SR4 uses multi-mode fiber (MMF) for short distances up to 100m, making it cost-effective for intra-rack connections. 400G DR4 uses single-mode fiber (SMF) and supports distances up to 500m, which is better for inter-rack or larger data center spans.
Q: Why choose the QSFP-DD form factor over OSFP? A: QSFP-DD offers excellent backward compatibility with QSFP28 and QSFP+ ports, allowing for a smoother migration path. It also provides high port density, enabling 36 ports of 400G in a 1U switch chassis, which is essential for maximizing data center space.
Q: Is this module compatible with non-Huawei equipment? A: While specifically optimized for Huawei CloudEngine series switches, our modules are manufactured to MSA (Multi-Source Agreement) standards, ensuring broad compatibility with major industry vendors. We also offer custom coding services to guarantee seamless integration with your specific hardware environment.
Optimized Power Efficiency: Advanced 7nm DSP and VCSEL technology keep power consumption below 10W, reducing TCO and cooling requirements.
High Reliability: Built-in Digital Diagnostic Monitoring (DDM) allows real-time tracking of optical power, temperature, and supply voltage to prevent downtime.
Superior Signal Integrity: Leverages PAM4 modulation with FEC (Forward Error Correction) to ensure error-free transmission across high-speed links.
Every Huawei QSFP-DD-400G-SR4 module undergoes a rigorous 100% testing procedure on original Huawei hardware to verify performance and compatibility. We provide:
3-Year Comprehensive Warranty.
Lifetime Technical Support from our expert engineers.
Fast global shipping with secure packaging.
