What is the maximum cable length specified by the IEEE 1394a standard?

  1. 2.5 meters

  2. 3 meters

  3. 4.5 meters

  4. 6 meters

The correct answer is: 4.5 meters

The maximum cable length specified by the IEEE 1394a standard, commonly known as FireWire, is 4.5 meters (approximately 15 feet). This standard supports high-speed data transfer between devices and specifies that a cable exceeding this length may experience signal integrity issues due to attenuation, which can result in data loss or errors during transmission. It's important to note that while the standard allows for up to 4.5 meters for standard cables, extensions beyond this length require the use of hubs or repeaters to maintain a reliable connection. Understanding this limitation is essential for anyone working with devices that utilize the IEEE 1394a standard, ensuring proper installation and troubleshooting of connections in a networked environment.
