What is true about 1000 Base-LX single mode transceivers?

The correct answer is C. 1000Base-LX doesn't need a Mode Conditioning Patch Cable to be operated with OM2 cables up. 1000Base-LX is designed for single-mode fiber, but it can operate over OM2 multimode fiber up to 550 m without requiring a Mode Conditioning Patch Cable. MCP cables are only needed when running LX optics over older MMF such as OM1 or FDDI-grade fiber due to differential mode
