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.

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.
