Explanation:
Detailed explanation-1: -Singlemode fibre has a much smaller core size of 9 microns and has a single light path and can travel much longer distances of up to 100km. These require more expensive electronics which operate in the 1310 and 1550nm windows and are typically used in longer distance LAN’s, Cable TV and telephony applications.
Detailed explanation-2: -Single-Mode Fiber (SMF) features a petite core, keeping the path of light narrow and allowing it to travel up to 100 km. Multimode Fiber (MMF) has a larger core that carries more data but is susceptible to signal quality issues over longer distances, making it better suited to short-haul networks and premises cabling.
