What is the maximum cable length for 1000BASE-LX with multimode fiber?

• A. 400 meters
• B. 5 kilometers
• C. 550 meters
• D. 1 kilometer

Answer: (C)

The maximum cable length for 1000BASE-LX with multimode fiber is indeed 550 meters. This specification is important for ensuring that the Gigabit Ethernet signal can effectively travel over the fiber medium without degradation or loss of data integrity. 1000BASE-LX is designed for long-distance network connections using optical fiber. It operates with two types of fiber: multimode and single-mode. While 1000BASE-LX is often associated with longer distances when using single-mode fiber—potentially extending up to 5 kilometers—multimode fiber is limited to shorter distances due to its related modal dispersion. In multimode fiber, the maximum distance supported by 1000BASE-LX is capped at 550 meters to maintain optimal performance. This is a critical piece of information for network design, ensuring that installations adhere to specifications to avoid connectivity issues that may arise from exceeding this distance. Recognizing the specific capabilities of 1000BASE-LX with both fiber types is essential for implementing effective network solutions.
