Axiom SFP Transceiver Modules are certified 100% compliant in all OEM applications. They are pre-configured with an application specific code to meet the requirement set forth by the router and switch OEMs. Axiom compatible transceivers perform, fit and function identically when compared to " "Original" Transceivers. Our transceivers fully comply with the multi-sourcing agreement (MSA) which enables them to work in all MSA compliant platforms. Axiom brand transceivers also function with other brands within the same network.
