What is the difference between SFP56-DD and traditional SFP56 modules?

SFP56-DD uses a dual-density electrical interface that provides two PAM4 electrical lanes, allowing it to support higher data rates while maintaining a compact form factor. Unlike standard SFP56 modules that typically support up to 50Gbps, SFP56-DD enables 100Gbps applications through two high-speed electrical channels.

What fiber type is required for this 100G SFP56-DD FR1 module?

This transceiver is designed for single-mode fiber (SMF), especially G.652 fiber commonly used in data centers and telecom networks. With a Duplex LC interface, it can integrate directly into existing single-mode fiber cabling systems.

Why does the module use PAM4 modulation?

PAM4 modulation increases data transmission efficiency by transmitting multiple bits per symbol, allowing higher bandwidth transmission over existing electrical and optical interfaces without requiring additional physical lanes.

Does this transceiver support FEC?

Yes. The module supports KP-FEC to improve signal reliability and enable stable 100G transmission over the specified 2km optical distance.

What are the advantages of choosing an SFP56-DD 100G module instead of a QSFP28 module?

The SFP56-DD form factor provides a smaller footprint and enables higher front-panel port density. It is suitable for applications where rack space optimization and high-density 100G connectivity are important considerations.
