SFP+ AOC (Active Optical Cables) are conceptually two SFP+ optical transceivers with a fiber optic cable permanently embedded into each end (the fiber cable cannot be removed). This results in a “ready to use” cable assembly, similar to passive Direct Attach Copper (DAC) cables, but with the benefit of internal active electronics to manage the host electrical interface and a longer reach, lighter weight cable.

 “SFP Plus”, or SFP+, are speed enhanced variations of the predecessor SFP form factor. SFP+ electrical and mechanical specifications were developed in 2006 under SFF Committee documents SFF-8431 and SFF-8432, which also defined the 10Gb/s Ethernet non-retimed high speed electrical interface. SFP+ is targeted at enabling 8Gb/s to 16Gb/s applications, such as 10Gb/s Ethernet as well as 8GFC and 16GFC Fibre Channel.

For the later developed 25Gb/s to 28Gb/s generation of SFPs, newer transceiver, connector and cage specifications were established under a new name, called “SFP28”. These transceivers are listed under the SFP28 designation.
