40G AOC has QSFP+ to QSFP+ form factor and 40G QSFP+ to 4x10G Breakout package. Active Optical Cables (AOC) combines optical fiber, control chip and modules. It uses electrical-to-optical conversion on the cable ends. AOC are light in weight, high end, low energy consumption, low interconnection loss, EMI immunity and flexibility, which provide good link performance and inter-operability. These cables are ideal for high density signal transmission typically seen in most data centers and in high performance computing applications.
