QSFP-DD ports incorporate a riding heatsink that can be sized independently of the optical module, added on top of the module, or placed between modules. This flexibility enables switch and routing
Compare SFP, SFP+, QSFP, QSFP28, and QSFP-DD by speed, lane count, compatibility, breakout options, power, and upgrade path.
It provides a QSFP-DD-to-QSFP-DD copper direct-attach solution. QDD-400-CuxM cables are suitable for very short links and offer a cost-effective way to establish a 400-Gigabit link between
The core difference between SFP and QSFP is lane count: SFP is a single-lane form factor (1G–25G), while QSFP aggregates 4 (or more) lanes to reach 40G, 100G, 200G and 400G (QSFP-DD). Choose
The QSFP-DD800 provides the industry''s highest bandwidth density of any transceiver module and backward compatibility to lower-speed QSFP pluggable modules and cables.
QSFP-DD is a new module and cage/connector system similar to current QSFP, but with an additional row of contacts providing for an eight lane electrical interface. It is being developed by the QSFP-DD
QSFP-DD ports are designed to be backward compatible with QSFP28 modules. This allows you to upgrade your spine switches to 400G/800G now while still utilizing your existing 100G
Find which switches support QSFP-DD modules. Our 2025 guide covers Cisco, Arista, Juniper and NVIDIA platforms with backward compatibility tips.
Compare SFP, SFP+, QSFP, QSFP28, and QSFP-DD by speed, lane count, compatibility, breakout options, power, and upgrade path.
A single 400G QSFP-DD transceiver can break out into four 100G QSFP28 connections, making it an ideal solution for high-density networking and optimizing fiber utilization.
A single 400G QSFP-DD transceiver can break out into four 100G QSFP28 connections, making it an ideal solution for high-density networking and
Quad Small Form-factor Pluggable Double Density (QSFP-DD) solution that fits into high-density switch and router client ports for optical interconnect links
