Polarization-maintaining fibers work by intentionally introducing a systematic linear in the fiber, so that there are two well defined polarization modes which propagate along the fiber with very distinct phase velocities. The beat length Lb of such a fiber (for a particular wavelength) is the distance (typically a few millimeters) over which the wave in one mode will experience an additional delay of one wavelength compared to the other polarization mode. Available from stock, these cables feature a high-quality polish, which leads to a typical return loss of 60 dB. Other options include cables with high extinction ratio (ER), cables with heating wire, AR-coated patch cables.
