The difference between single-mode and dual-mode fiber optic patch cords

The main difference between single-mode fiber (Single-mode Fiber) and multi-mode fiber (Multi-mode Fiber) lies in the transmission mode, light source type, transmission distance and applicable scope. The following is a detailed introduction:
transmission mode. Single-mode optical fiber transmits a single high-quality optical signal, with high bandwidth and long transmission distance, and is suitable for long-distance high-speed transmission, such as telecommunications and multimedia networks; multi-mode optical fiber transmits a variety of optical signals with longer transmission distance. Short, suitable for short distances or situations with low performance requirements, such as local area networks. 24567
type of light source. Single-mode optical fiber usually uses a laser or laser diode as the light source, because the laser light source can produce a single mode of light with high brightness and high power; multi-mode optical fiber uses LED (light emitting diode) or vertical cavity surface emitting laser (VCSEL) as the light source. , because LED light sources can produce multiple modes of light, and the light is more dispersed.
