Detailed explanation-1: -The most significant difference between SMF and MMF is that SMF provides higher spectral efficiency. It can support more traffic over a single fiber using more channels at higher speeds. In MMF, cabling support for higher bit rates is limited by its large core size.
Detailed explanation-2: -The maximum transmission distance for MMF cable is around 550m at the speed of 10Git/s. It can transmit farther at lower data rates, such as going about 2km at 100Mb/s.
Detailed explanation-3: -single mode fiber is designed to propagate a single light mode whereas multimode supports multiple simultaneous light modes. This difference impacts bandwidth, signal transmission distance and signal stability which we’ll explore later.
