QSFP + Active Optical Cables (AOCs) are active optical cables of
the QSFP + interface. The module has a photoelectric conversion
device inside to convert the electrical signals into optical
signals and transmit distances up to 100 meters. The products have
four channels, each channel transmission rate up to 10Gb / s, rate
of 40Gb / s. Its low power consumption, low bit error rate, easy to
manage, high-performance features are widely used in short distance
high-speed connection such as 10 Gigabit Ethernet, 10 Gigabit
switches, 10 Gigabit servers, supercomputers, cloud computing and
cloud storage networks.
