• Expands on the QSFP56 pluggable form factor, a widely adopted four-lane electrical interface
• 2×1 stacked integrated cage / connector
• Cage design optimizations and module case optimizations enable thermal support of at least 7w per module
• QSFP-DD electrical interfaces will employ eight lanes that operate 50 Gbps PAM4 modulation, providing solutions up to 400 Gbps aggregate
• QSFP-DD can enable up to 14.4 Tbps aggregate bandwidth in a single switch slot

• By quadrupling aggregate switch bandwidth while maintaining port density, QSFP-DD will support continuing growth in network bandwidth demand and datacenter traffic
• Systems designed with QSFP-DD modules will be backwards compatible, allowing them to support existing QSFP modules and provide flexibility for end users and system designers

QSFP-DD 400G Eoptolink’s EOLD-134HG-5H QSFP-DD DR4, 4x100G Optical transceiver module are designed for use in 400 Gigabit links over 500m singlemode fiber. They are operating on 1310nm wavelength, and are compliant with the QSFP-DD MSA. Digital diagnostics functions are available via the I2C interface, as specified by the QSFP-DD MSA.
