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

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.
