Axiom DWDM 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.
