Axiom SFP-25G-BX40D-I-AX 25GBASE-BX40-D SFP+ | Cisco Compatible — SFP-25G-BX40D-I-AX

Increase link capacity without increasing fiber count. The Axiom SFP-25G-BX40D-I-AX is a Cisco-compatible 25GBASE-BX40-D SFP+ transceiver designed for environments where efficient fiber use and straightforward switch integration are priorities. By supporting bidirectional 25 GbE transport, it helps teams preserve cabling resources while moving to higher-speed access and aggregation layers. This module is a practical fit for network upgrades that need more throughput but cannot justify a full cabling overhaul. BX40-D optics are valued in dense switching environments because they reduce fiber consumption and simplify port planning. For infrastructure teams, that means cleaner deployments, easier scaling, and fewer constraints when expanding uplinks or replacing older optics. Axiom positions this module for Cisco environments that need a compatible, procurement-friendly transceiver for 25 GbE links. It is the kind of component that earns its place in a budget by reducing infrastructure friction while supporting a faster network tier. Ideal For 25 GbE switch uplinks in Cisco-based access layers Aggregation links where single-fiber optics reduce cabling demand Data center port expansions that need higher throughput without new fiber runs Network refresh projects that standardize on Cisco-compatible transceivers Why This Product 1 25 GbE throughput for higher-speed switch links 2 Single-fiber bidirectional design to reduce cabling demand 3 Cisco compatibility for controlled infrastructure rollouts 4 SFP+ form factor for dense port environments
