Final answer:
The 'W' in 10GBASE-SW stands for 'Short Wavelength,' which is a signaling type used in 10 Gigabit Ethernet networks over fiber optic cables, suitable for short distances.
Step-by-step explanation:
The "W" in the standard 10GBASE-SW stands for "Short Wavelength" signaling. It refers to a type of optical fiber technology that uses shorter wavelengths, typically around the 850nm range, for transmitting data over a network. This standard is used in data communication for 10 Gigabit Ethernet networks over fiber optic cables and is particularly suitable for short-distance communication, such as within data centers.
