What is the IEEE standard for 1000BASE-LX?

• A. 802.3ae
• B. 802.3ab
• C. 802.3z
• D. 802.3ad

Answer: (C)

The IEEE standard for 1000BASE-LX is identified as 802.3z. This standard specifies the physical media and signaling for Gigabit Ethernet over fiber optic cables, particularly for long-wavelength applications. The "LX" stands for "long wavelength," indicating that this standard is optimized for long-distance data transmission, typically using single-mode fiber and capable of distances up to 10 kilometers. In the context of Gigabit Ethernet standards, each designation corresponds to different types of media and signaling. For example, 802.3ae pertains to 10 Gigabit Ethernet, while 802.3ab relates to Gigabit Ethernet over copper cabling (the popular 1000BASE-T standard). The standard 802.3ad focuses on link aggregation, allowing multiple network connections to combine for increased bandwidth. Therefore, understanding the specific assignments of each of these IEEE standards is crucial for networking professionals as it relates to choosing the appropriate technology for given environmental and performance requirements.
