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

1. USB 2.0

2. IEEE 1394b

3. Ethernet

4. Wi-Fi 6

The correct answer is: IEEE 1394b

The standard that supports data transfer rates up to 800 Mbps with a maximum cable length of 100 meters is IEEE 1394b, also known as FireWire 800. This specification enhances prior versions of FireWire technology by enabling higher data transfer speeds, making it suitable for applications that require fast data rates, such as video capture and high-speed hard drives. IEEE 1394b achieves speeds of 800 Mbps over twisted pair cables and can maintain this rate up to a distance of 100 meters, providing flexibility for many multimedia and data applications. This makes it particularly valuable in environments where high-speed data transfer is critical, such as in professional video environments or for connecting multiple devices in a production setup. In contrast, other options like USB 2.0 support lower speeds (up to 480 Mbps) and have different cable length limitations. Ethernet operates at various speeds, but typical standards that extend to 100 meters, such as 100Base-T, do not reach 800 Mbps. Finally, Wi-Fi 6 introduces improvements in wireless technology but does not meet the wired data transfer specifics outlined in the question.
