Copper, fiber, SFP, and power over Ethernet expansion modules can be added to a Stratix 8000/8300 system. Copper and Fiber expansion modules can be combined to provide additional copper and fiber ports on your system. SFP Expansion modules can add up to 12 fiber ports with the ability to mix and match multimode and single mode SFPs. Power over Ethernet ( PoE) modules pass electrical power along with data on Ethernet cabling. This allows a single cable to provide both data connection and electrical power to devices such as wireless access points.
