Which property is shared by 10GBase-SR and 10GBase-LR interfaces? (CCNA 200-301)
Which property is shared by 10GBase-SR and 10GBase-LR interfaces?
A. Both use the single-mode fiber type.
B. Both require UTP cable media for transmission.
C. Both require fiber cable media for transmission.
D. Both use the multimode fiber type.
Solution
Correct answer: C. Both require fiber cable media for transmission.
10GBase-SR (Short Range) and 10GBase-LR (Long Range) are both 10 Gigabit Ethernet standards that use optical fiber as the transmission medium. However, they differ in the type of fiber used and the transmission distance they support.
10GBase-SR uses short wavelength lasers and multimode fiber, which limits its transmission distance to around 300 meters. On the other hand, 10GBase-LR uses long wavelength lasers and single-mode fiber, which allows it to transmit data over longer distances of up to 10 kilometers.
Therefore, both 10GBase-SR and 10GBase-LR interfaces require fiber cable media for transmission, but they use different types of fiber and support different transmission distances.
