Quizplus · Accepted Answer

850 nm multimode fiber is the most commonly used for fiber transmission links in LANs due to its cost-effectiveness and compatibility with Ethernet technology. Single-mode fiber and 1,550 nm wavelength are typically used for longer distance transmissions or in specific applications, such as high-speed data centers or telecom networks.
