Compatible transceivers
Important:
Extreme Networks recommends using SFP and SFP+ transceivers as they have been through
extensive qualification and testing. Extreme Networks will not be responsible for issues related
to third party transceivers.
• The VSP 4450GTX-HT-PWR+ operates in forgiving mode for SFP, and for coarse wave
digital multiplexing (CWDM) and dense wave digital multiplexing (DWDM) SFP+
transceivers. This means that the switch will bring up the port operationally when using
third party SFP, or SFP+ transceivers. Extreme Networks does not provide support for
operational issues related to these transceivers, but they will operate and the port link will
come up. The switch logs the device as an unsupported or unknown device.

installation instructions, see Installing Transceivers and Optical Components on VSP Operating
System Software.
Optical power considerations
When you connect the device to collocated equipment, ensure that enough optical attenuation exists
to avoid overloading the receivers of each device. You must consider the minimum attenuation
requirement based on the specifications of third-party equipment. For more information about
minimum insertion losses for the optical products, see Installing Transceivers and Optical
Components on VSP Operating System Software.
