ETERN Optoelectronics 400G QSFP-DD DR4 500m Optical Transceiver
The FLS400C005S is a high-performance 400Gb/s QSFP-DD DR4 optical module designed for 500m reach over single-mode fiber (SMF), fully compliant with the IEEE 802.3bs 400GBASE-DR4 standard.
Engineered for next-generation data center interconnects, this transceiver converts 8 channels of 53.125Gb/s PAM4 electrical signals into 4 parallel channels of 106.25Gb/s optical data. By utilizing sophisticated EML transmitters and high-sensitivity PIN receivers, it ensures high-density, low-latency connectivity. Its QSFP-DD form factor supports the massive bandwidth requirements of cloud scale infrastructure while maintaining rigorous thermal and power efficiency.
Key Technical Highlights
- Parallel Fiber Architecture: Utilizes 4 parallel lanes at 1310nm to achieve 400G throughput over 500m SMF links.
- PAM4 Modulation: High-efficiency 8x50G PAM4 electrical interface compliant with IEEE 802.3bs standards.
- Reliable Optical Engine: Integrated with premium EML lasers and PIN photodetectors for consistent performance in 0-70℃ environments.
- Industry Standards Compliance: Fully compatible with QSFP-DD MSA and CMIS for robust multi-vendor interoperability.
Applications
Ideal for 400GBASE-DR4 Ethernet high-speed interconnects within mega data centers, enterprise backbone networks, and leaf-spine architectures using MPO-12 or MPO-8 fiber interfaces.
