Single-mode Mono-Partial Fiber Method

- Jan 02, 2019-

There are two ways to form a single-mode single-offset transmission:

(1) Forming a tunnel next to the fiber core to omit the polarization mode of a line; 

(2) Select the appropriate conditions to separate the cutoff wavelength of two polarization modes, at a certain wavelength, one polarization mode is closed and the other is transmitted. Strictly speaking, only polarized fiber is the real single-mode fiber.
