CXP2 AOC (Active Optical Cables) are conceptually two CXP2 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.

The new CXP2 twelve channel transceiver footprint was established circa 2016 as part of enhanced InfinBand Volume 2 specifications in support of 12X EDR multi-channel parallel links. While InfiniBand generally does not commercially adopt CXP2 12X links, the form factor has seen significant deployment in custom “fat pipe” interconnect links associated with server, chassis and backplane extensions at data rates up to 28Gb/s per lane. Optical variants are available in MPO connectored (12+12) and AOC (active optical cable) configurations.
