Juniper QFX10K-12C-DWDM DWDM Interface Card

What It Is

The Juniper QFX10K-12C-DWDM is a line/interface card for the QFX10000 series switches, designed for spine-level and data center core deployments. It provides dense wavelength-division multiplexing (DWDM) support and operates under Junos OS, powered by the Juniper Q5 ASIC with deep buffers.

Technical Details

• Form Factor: Line/interface card for QFX10000 chassis
• Platform: Juniper QFX10000 series (spine/core data center)
• Multiplexing: DWDM (dense wavelength-division multiplexing)
• Chipset: Juniper Q5 ASIC with deep buffers
• Operating System: Junos OS
• Role: Spine-tier IP fabric aggregation, leaf switch traffic aggregation

Configuration & Options

• Installs into a line card slot on a QFX10000 chassis
• Operates as part of the QFX10K DWDM full stack
• Compatible with the QFX10000 chassis family
• Requires appropriate DWDM optical modules (not included)
• Intended for EVPN-VXLAN network builds and inter-data-center connectivity

Operating Conditions

This card is deployed in spine-tier IP fabric roles within data center cores, aggregating east-west traffic from leaf switches. It supports EVPN-VXLAN architectures and enables inter-data-center DWDM links. The card runs on Junos OS in QFX10000 chassis, suitable for high-capacity core environments requiring deep buffering.
