Which standard provides for data transfer rates up to 800 Mbps with a maximum cable length of 100 meters?

The standard that provides for data transfer rates up to 800 Mbps with a maximum cable length of 100 meters is IEEE 1394b, also known as FireWire 800. This standard is designed for high-speed data transfer between devices, such as audio and video equipment, and supports various data transfer modes. IEEE 1394b achieves its high transfer rates through a technology that allows multiple devices to be connected in a daisy chain, making it particularly useful in professional audio/video applications where bandwidth is critical.

In contrast, while USB 3.0 does offer high data transfer rates, its maximum speed is significantly higher (up to 5 Gbps) and is not defined by the same length considerations as IEEE 1394b. Ethernet standards related to the 802.11 series are primarily concerned with wireless networking and do not provide the specified transfer rates and cable length. SATA 3.0 focuses on internal connections between a computer's motherboard and storage devices, offering speeds up to 6 Gbps, which also does not align with the data transfer rate and maximum length specified in the question. Thus, IEEE 1394b is the correct choice, as it uniquely meets both the speed and distance requirements detailed in the question.
