QSFP-DD can enable up to 14.4 Tbps aggregate bandwidth in a single switch slot. QSFP-DD electrical interfaces will employ eight lanes that operate up to 25 Gbps NRZ modulation or 50 Gbps PAM4
August 7, 2020 – QSFP-DD Hardware Specification for QSFP DOUBLE DENSITY 8X PLUGGABLE TRANSCEIVER – Rev 5.1 July 11, 2019 – QSFP-DD Hardware Specification for QSFP
Find which switches support QSFP-DD modules. Our 2025 guide covers Cisco, Arista, Juniper and NVIDIA platforms with backward compatibility tips.
They include: QSFP+: This is the most common type that supports up to 40Gbps in data centers. QSFP28: It has a higher bandwidth than QSFP+,
The QSFP-DD OLS can extend the reach of a 400G QSFP-DD ZR/ZR+ link (from 40 to 130 km or longer, depending on fiber characteristics), the channel count, and the line rate of the wavelength.
These 200G Q-DD AOCs automatically configure a Q-DD port to operate in 4-channel QSFP56 mode. Because of the 2xQSFP28 ends, this limits the Q-DD

Furthermore, 40G QSFP+, 100G QSFP28, and 200G QSFP56 are among the currently available QSFP form factor varieties with which QSFP-DD is
*Wattage may impact operating temperature for select switches. Aruba 9300 switch series limit the use of QDD optics/AOCs if running at low-line AC Voltage
What is QSFP-DD? QSFP-DD is an advanced hot-pluggable optical transceiver form factor that doubles the bandwidth density of traditional QSFP28
QSFP-DD Interconnect System''s 8-lane electrical interface transmits up to 28 Gbps NRZ or 56 Gbps PAM-4, up to 200 or 400 Gbps aggregate, with the same footprint as QSFP Interconnects, making
Amphenol Commercial QSFP Double Density (DD) Interconnect System is backwards mating compatible with QSFP products. The connectors
QSFP-DD modules Always refer to the Datasheet or QuickSpecs for the switch product to see the current list of supported transceivers. Datasheets/QuickSpecs do not usually detail specific notes for
Key takeaway: QSFP-DD = density + compatibility. OSFP = cooling + scalability. Deployment Considerations Switch Compatibility Some switches only
QSFP-DD Interconnect System enables faceplate density equal to the current 2x1 QSFP form factor, but with 8-lane ports. In other words, a total of 256 differential
