Axiom 100GQSFP-LR4-4-AX 100G QSFP28 LR4 | Cisco Compatible, Enterprise — 100GQSFP-LR4-4-AX

Move 100 GbE traffic across longer distances with this QSFP28 LR4 optic from Axiom, designed for Cisco compatibility. It is built for single-mode fiber deployments where short-reach optics are not enough and where stable long-distance transport is required between aggregation layers, buildings, or remote network rooms. LR4 optics are a practical choice for teams standardizing on 100 GbE while preserving reach and link quality. The QSFP28 form factor supports modern high-density switching platforms, and the LR4 specification is commonly used when you need to span up to 10 km over single-mode fiber. That makes this module well suited for campus backbones, data center interconnects, and other infrastructure paths where cable plant distance is a real design constraint. Choose this optic when the network design calls for long-reach 100 GbE without moving to a different speed tier. It gives procurement and engineering teams a clear path to extend capacity while keeping the deployment aligned with Cisco-based infrastructure. Ideal For Connect data center switches across separate rooms or buildings Support campus backbone links that require 100 GbE over single-mode fiber Link aggregation layers in long-reach enterprise network designs Provide 100 GbE transport for Cisco-based infrastructure upgrades Why This Product 1 LR4 optics provide long-reach transport where SR optics cannot cover the distance 2 QSFP28 form factor fits high-density 100 GbE switching platforms 3 Cisco compatibility supports standardized enterprise deployments 4 Single-mode fiber design suits campus and inter-building links
