This QSFP+ Breakout AOC (Active Optical Cables) are a hybrid construction made with a single QSFP+ optical transceiver on one end and four independent SFP+ optical transceivers on the other end, with a fiber optic cable permanently embedded into each end (the fiber cable cannot be removed). This results in a “ready to use” QSFP+ to four SFP+ “Breakout” 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. The target application is QSFP+ based Top Of Rack (TOR) switches which need to communicate to independent SFP+ server Network Interface (NIC) cards or other legacy SFP+ based targets.
