The 100G SFP56-DD SR2 Optical Module delivers 100 Gbps high-speed optical performance in an ultra-compact, double-density form factor — ideal for dense data center and cloud network environments. Built on 2×50G PAM4 modulation, this solution supports high-performance links while preserving a small physical footprint for maximum port density.
Key Features:
- Compact Double Density Design: The SFP56-DD form factor retains the small size of legacy SFP+ modules while enabling 100 Gbps transmission — shrinking board space usage by 35 % compared with larger QSFP28 interfaces and supporting higher port capacity in the same system footprint.
- Efficient PAM4 Modulation: Leverages 2×50G PAM4 lanes for reliable, high-speed optical links suitable for modern network fabrics.
- Standard Compliance: Fully compliant with SFP56-DD MSA specifications for industry interoperability.
- Low Power Consumption: Designed to operate at < 3 W, making it well-suited for high-density deployments where power and thermal constraints are critical.
Applications:

This solution helps network architects achieve higher throughput and improved port scalability without compromising on power efficiency or space utilization — ideal for evolving data center and cloud infrastructures.
