      What is single-mode fiber? What are the advantages and disadvantages?

      Single-mode fiber (SingleModeFiber) is an optical fiber that can only transmit one mode at a specified wavelength. The center glass core is very thin (core diameter is generally 9 or 10μm). Therefore, its inter-mode dispersion is very small, suitable for remote communication However, there are al...
