Keep 1 GbE fiber links simple when strand count is tight. The AddOn MA-SFP-1GB-BX-D-AO is a TAA-compliant 1000BASE-BX SFP transceiver designed for Cisco Meraki compatibility, delivering bidirectional Gigabit Ethernet over a single strand of single-mode fiber. That makes it a practical fit for access-layer uplinks, building interconnects, and other deployments where conserving fiber pairs matters. This module uses an LC connector and operates at 1 GbE, giving network teams a familiar optics format for standardized switch and appliance environments. BiDi optics are especially useful in retrofit projects and constrained pathways, where pulling additional fiber is costly or impractical. By matching the BX-D side of the link, it supports clean point-to-point connectivity without adding unnecessary complexity. For procurement teams, the TAA-compliant designation matters in regulated and public-sector environments. For operations teams, the value is in reducing fiber consumption while preserving a stable Gigabit path. AddOn’s compatibility-focused approach helps avoid overpaying for branded optics when the deployment only needs verified interoperability and the right physical interface.
