Introduction: The Shift from QSFP-DD to OSFP As data centers transition from 400G to 800G interconnects, bandwidth demand, power efficiency, and thermal constraints have forced the
Find which switches support QSFP-DD modules. Our 2025 guide covers Cisco, Arista, Juniper and NVIDIA platforms with backward compatibility tips.
QSFP-DD supports native breakout to QSFP28, while OSFP requires breakout cables. These are among the most popular aggregation scenarios, ideal for
Eight-Lane (QSFP-DD): The core of 400G and 800G connectivity. It uses eight 50G or 100G lanes, allowing a single massive port to act as an entire distribution hub. You cannot simply
This enables the QSFP-DD cages in switches to support backwards compatibility to 4-channel QSFP56, QSFP28, and QSFP+ devices, which engage only the first row of 4 pins in the 8
July 11, 2019 – QSFP-DD Hardware Specification for QSFP DOUBLE DENSITY 8X PLUGGABLE TRANSCEIVER – Rev 5.0 May 8, 2019 – Common Management Interface
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 QSFP-400G
QDD-400-CuxM cables are suitable for very short links and offer a cost-effective way to establish a 400-Gigabit link between QSFP-DD 400G ports of switches/routers within racks and
Product overview The FS® 400GBASE Quad Small Form-Factor Pluggable Double Density (QSFP-DD) portfolio offers customers a wide variety of super high-density transceiver modules and the flexibility
Powered by Greylock and Delphi DSP ASICs, and silicon photonic integrated circuits (PICs) for an optimized co-packaged design with 3D Siliconization. Supports an expansive list of interoperability
Enterprise campus networks employ QSFP transceivers for building-to-building connectivity and core switching infrastructure. Building Interconnects:
Datasheet More information on this Arista DCS-7280CR3AK-24D12 7280R3A 24-Port 100GbE QSFP and 12-Port 400GbE QSFP-DD Switch Router is available in the official Arista 7280R3A Series Data
The QSFP-DD modules are our new generation of 400G transceiver modules based on a QSFP-DD form factor. (See Figure 1).
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
Built for hyperscale data centers, these 400G Ethernet solutions deliver massive scale, low latency, and exceptional power efficiency for cloud applications.
