After the switch is secured to the rack, install optional components.
ExtremeSwitching switches support the use of pluggable transceivers and cables in the SFP+, SFP28, QSFP+, and QSFP28 formats.
For a list of the optical components supported with ExtremeSwitching 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+, SFP28, QSFP+, and QSFP28 ports.
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 7720 Series switches running either Fabric Engine or Switch Engine, interfaces 0/1 through 0/27 and 0/29 through 0/32 support up to 4 10GbE, 4 25GbE, 1 40GbE, or 1 100GbE ports each in breakout mode when using the appropriate optics. Interface 0/28 cannot be partitioned, but it supports 1 40GbE or 1 100GbE port. See the Extreme Optics website to determine the appropriate optics.
