Axiom 800G 2xFR4 QSFP-DD 2 km SMF | Juniper Compatible, LC Duplex — QDD-2X400G-FR4-P-AX

Move 800G traffic farther without changing the shape of your network. This Axiom QSFP-DD 2xFR4 transceiver is designed for Juniper-compatible deployments that need high-capacity optical transport over single-mode fiber. With dual LC duplex connectivity and a 1,271-1,331 nm wavelength range, it supports long-reach links up to 2 km while maintaining the port efficiency infrastructure teams expect from dense switching platforms. For environments where every rack unit and every uplink matters, this module helps preserve bandwidth headroom without forcing a redesign of the fiber plant. It is a practical fit for aggregation, interconnect, and data center extension scenarios where 800G throughput must travel beyond short-reach optics. The 2xFR4 architecture is built for operators who need more distance than SR optics can provide, but still want a compact pluggable form factor that slots into existing QSFP-DD infrastructure. Axiom positions this module as a compatible alternative for Juniper environments, giving procurement teams a way to meet performance targets while controlling optics spend. That matters when you are scaling links across multiple switches or standardizing on a repeatable transceiver profile for high-volume deployments. Ideal For 800G switch-to-switch uplinks across a campus backbone Data center interconnect links requiring 2 km single-mode reach Aggregation-layer optics for high-density Juniper environments Standardized transceiver deployment for large-scale optical refreshes Why This Product 1 Longer reach than short-range 800G optics 2 Juniper-compatible for mixed-vendor planning 3 LC duplex simplifies fiber terminations 4 2 km support suits campus and interconnect links
