Extreme Networks switches support the use of pluggable transceivers and cables in the SFP, SFP+, SFP28, QSFP-DD, QSFP+, and QSFP28 formats.
For a list of the optical components supported with Extreme Networks devices, see the Extreme Optics website.
Extreme Networks offers several optical transceiver modules for transmitting and receiving data over optical fiber rather than through electrical wires.
Direct-attach copper and fiber cables provide connections between populated SFP, SFP+, SFP28, QSFP-DD, QSFP+, and QSFP28 ports.
