Key Features
- 4 x 400 GbE line card
- Modular expansion for QFX5700 chassis
- High-density uplink capacity
- Designed for data center fabric scaling
- Juniper QFX5K platform component
- 400 GbE interface class
- Line card form factor
- Increase fabric bandwidth with four 400 GbE ports
Add 400 GbE capacity where it changes the design of the network, not just the port count. The Juniper QFX5700 4X400G LC delivers four 400 GbE interfaces in a modular line card format, giving infrastructure teams a clean path to higher fabric bandwidth without replacing the entire switch chassis.
Built for demanding data center environments, this line card is suited to spine, aggregation, and high-speed interconnect roles where oversubscription and growth planning are constant concerns. Its modular approach helps preserve investment in the QFX5700 platform while increasing throughput exactly where it is needed.
For teams standardizing on Juniper switching, the 4x400G option supports dense, high-speed architectures that are easier to scale and simpler to plan around than piecemeal port expansion. It is the kind of component that earns its place in networks carrying storage traffic, east-west application flows, and large-scale virtualization workloads.
Ideal For
- Data center spine expansion for high-throughput leaf-spine fabrics
- High-speed aggregation for storage and virtualization traffic
- Uplink scaling in large east-west traffic environments
- Modular capacity growth in Juniper QFX5700 deployments
Why This Product
- 1Four 400 GbE ports for maximum uplink density
- 2Modular line card preserves chassis investment
- 3Built for high-throughput data center fabrics
- 4Better fit than lower-speed expansion for spine roles
