Description
400G QSFP56-DD SR8 is designed for use in 400 Gigabit Ethernet links on up to 100m of multi mode fiber.
400G QSFP56-DD SR8 Product Overview
400G QSFP56-DD SR8 is designed for use in 400 Gigabit links over 100m multimode fiber. The SFP is compliant with the QSFP-DD MSA. Digital diagnostics functions are available via the I2C interface, as specified by the QSFP-DD MSA. These optical transceivers addresses the technical challenges of achieving high speed 400G interconnections. The transceivers have four optical lanes that operate at 100Gbps PAM4 modulation, providing solutions up to 400 Gbps. The transceivers have on the electrical side 8 lanes of 53.125Gbps PAM4. They are compliant with the QSFP-DD MSA (DD = Double Density). Digital diagnostics functions are available via the I2C interface, as specified by CMIS (Common Management Interface Specification).
