Juniper QFX10000-36Q 36-Port 40GbE QSFP+ Line Card | Data Center

Add dense, high-speed fabric capacity to a Juniper QFX10000 modular switch with the QFX10000-36Q line card. This expansion module delivers 36 x 40 GbE QSFP+ ports and 12 x 100 GbE QSFP28 ports, giving infrastructure teams a clean path to scale optical connectivity without replacing the chassis platform. Designed for data networking and optical network deployments, the module supports 40GBase-X over optical fiber and is built for environments where port density, uplink speed, and chassis-based architecture matter more than commodity switching. At approximately 22.60 lb, it is a substantial line card intended for serious fabric expansion, not edge access. For teams standardizing on Juniper QFX10000 modular Ethernet switches, this module helps preserve investment while increasing aggregate bandwidth and simplifying high-speed interconnect design. It is a strong fit for data center cores, spine layers, and aggregation points that need more 40 GbE access with a clear migration path to 100 GbE.
