Active Optical Cable (AOC) connectivity solutions

        1.Overview of Active Optical Cable AOC
        The appearance of active optical cable AOC is similar to DAC, but the transmission mode and application environment are different. Active optical cable AOC has four types: 10G SFP+ AOC, 25G SFP28 AOC, 40G QSFP+ AOC and 100G QSFP28 AOC, and the main difference between them is that the rates are different, and the following section focuses on the connection scheme of active optical cable AOC.
        2. Active optical cable structure and signal transmission method
        Active Optical Cable AOC uses a section of fiber optic cable to connect the two high-density connectors, with the help of external power supply for signal transmission, the transmission mode is electrical → optical → electrical conversion, the electrical signal is converted into an optical signal inside the connector at the A-end, the optical signal is then transmitted through the middle of the fiber optic cable to the connector at the B-end, and then inside the connector at the B-end, the optical signal is converted into an electrical signal.
        3. Features and advantages of active optical cable
        Active Optical Cable AOC has low power consumption, small size, light weight and strong heat dissipation, it is compared with copper cable, the transmission distance is farther (up to 100~300m), and transmission performance is also better, compared with the optical module, there is no interface contamination of active optical cable, which greatly improves the stability and reliability of the system and reduces the management costs of the server room.
        4. Active fiber optic cable connection
        4.1 for connection between racks
        Active Optical Cable AOC is used in data centers to connect between racks and racks of ideal cables, the general length of 5 ~ 30m within the best, 5m or less short-distance connection can choose a high-speed cable DAC, 30m or more long-distance connection you can choose a combination of optical modules + fiber optic patch cords, the details are shown in the figure below:

        4.2 For connection between switches and between switches and servers
        40G QSFP+ to 4*SFP+ active fiber optic cable can connect 2 switches, it can also connect the switch at the top of the 10G rack and the server with 10G NIC in the rack to realize 10G network transmission, details are shown in the following figure:

        AOC can be customized length: in order to meet the needs of different customers launched active optical cable AOC customization services, more scientific layout design, more reasonable cable length, to help you save wiring space at the same time also be able to save wiring costs.
