Question

Quizplus · Accepted Answer

The option that supports duplex links of up to 550m of multimode fiber and up to 5km of single-mode fiber is 1000BASE-LX. This is because it operates at a longer wavelength range of 1270-1355 nm, which allows for longer transmission distances compared to other options. 1000BASE-SX has a shorter transmission distance of up to 550m over multimode fiber, and 1000BASE-T is for copper cabling. 1000BASE-CX is designed for short-distance links over copper cable.
