Keep access-layer links stable with a 1000BASE-BX10-D SFP transceiver designed for Cisco GLC-BX-D-I compatibility. Built for Gigabit Ethernet over single-mode fiber, this optic supports bidirectional transmission on a single strand, helping reduce fiber consumption in dense campus and enterprise edge environments. For teams standardizing on Cisco infrastructure, the AXG95546 gives you a practical replacement or expansion option without changing the network design. Its BX10-D architecture is well suited to point-to-point runs where you need dependable 1 GbE connectivity across longer distances than multimode optics typically support. That makes it a strong fit for access switches, distribution uplinks, and remote closets where fiber count and rack space both matter. TAA compliance adds procurement value for public sector and regulated environments that require sourcing alignment. When the goal is to preserve uptime, maintain compatibility, and avoid unnecessary redesigns, this transceiver delivers the right balance of reach, density, and deployment simplicity.
