Active optical cable AOC is a new type of communication cable. Compared with passive cables or cable-based systems, it has the advantages of high transmission rate, long transmission distance, and low power consumption. It is an ideal solution for data centers, consumer electronics and other fields.

Active optical cable AOC has different packages and rates: 10G SFP+ AOC, 25G SFP28 AOC, 40G/56G QSFP+ AOC, 100G QSFP28 AOC, 200G QSFP-DD AOC, etc. In this article, ETU-LINK will introduce you to 56G QSFP+ AOC active optical cable.

Before formally introducing the 56G QSFP+ AOC active optical cable, we first understand the QSFP+ AOC active optical cable. QSFP+ AOC active optical cable is composed of optical fiber and two QSFP+ connectors (one at each end). The optical fiber is multi-mode optical fiber, which requires the use of external power supply to convert electrical signals and optical signals. It is mainly divided into 40G QSFP+ AOC active optical cable, 40G QSFP+ to 4X10G SFP+ AOC active optical cable and 56G QSFP+ AOC active optical cable.

56G QSFP+ AOC active optical cable is a high-efficiency integrated optical cable assembly product (four channels full-duplex) designed for short-distance data communication and interconnection applications. Each channel can operate at a rate of up to 14.025Gb/s. transfers data, providing an aggregate rate of 56Gb/s. The maximum link length is 100 meters on OM3 multi-mode fiber and 150 meters on OM4 multi-mode fiber. Built-in 850nm VCSEL laser, PIN array, integrated driver and receiver chip, supports standards including InfiniBand FDR, 56G Ethernet, 16G Fiber Channel, QSFP MSA and IEEE P802.3ba 40GBASE-SR4, and is compatible with various brands of servers, switch transmission equipment, etc.

Transmission principle:

Both ends of the cable (end A and end B) are QSFP optical module devices respectively, and end B and end A transmit symmetrically. At the A end, the data input Din is an electrical signal. The electrical signal is converted into an optical signal of a specific wavelength through the electro-optical conversion device (E-O Converter). The optical signal is modulated and coupled and then input into the optical cable. The optical signal reaches the B end through the optical cable. Finally, the photoelectric detection device (O-E Converter) detects the optical signal and amplifies it, and Dout outputs the corresponding electrical signal.

56G QSFP+ AOC active optical cable is suitable for supercomputers and SDR, DDR and QDR based on the InfiniBand standard. It is a solution for data centers and high-performance computers.
