Install Optional Components

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.

Pluggable Transceiver Modules

Extreme Networks offers several optical transceiver modules for transmitting and receiving data over optical fiber rather than through electrical wires.

Optical Cables

Direct-attach copper and fiber cables provide connections between populated SFP, SFP+, SFP28, QSFP-DD, QSFP+, and QSFP28 ports.

Breakout cables

The copper breakout cables are terminated with optical connectors and are available in 1m, 3m, 5m, or greater lengths. No additional connectors or cabling are required when using the copper breakout. When using the fiber breakout cables, additional 10Gb optics are required.

For the 8520-48Y switch, interfaces 0/49 and 0/56 support up to 8 10GbE or up to 8 25GbE ports in breakout mode when using the appropriate optics. See the Extreme Optics website to determine the appropriate optics.

For the 8520-48XT switch, interfaces 0/49 and 0/54 support up to 8 10GbE or up to 8 25GbE ports in breakout mode when using the appropriate optics. See the Extreme Optics website to determine the appropriate optics.

The first and last ports of the 8520 Series uplinks are capable of breakouts (they are color coded differently too).

For 8520-48Y models, the 1st and last uplink ports are ports 49 and 56.
For 8520-48XT models, the 1st and last uplink ports are ports 49 and 54 .
