+PC connector is used with Fabry-Perot interferometers when we wish to have some reflection at the end of the fiber.
+Otherwise, APC connectors are used.

+## Multi-mode and Single-mode fibers {#multi-mode-and-single-mode-fibers}

+If laser is used (fiber interferometer for instance), a single-mode fiber should be used and the wavelength of the mode should be matched with the wavelength of the laser.
