Introduction to Single Mode Fiber

Single mode fiber (SMF) is a type of optical fiber designed to carry a single mode of light - the fundamental mode - as the information carrier. It has a very small core diameter, typically around 8 - 10 microns, which allows light to travel in a straight line with minimal dispersion. This characteristic enables single mode fiber to achieve extremely high bandwidths and long - distance transmission capabilities, making it the preferred choice for high - speed, long - haul telecommunications networks, data centers, and other applications where large amounts of data need to be transmitted over great distances with low loss.
