Visibility of a 220 km Long Deployed Optical Fiber Sagnac Interferometer

We demonstrate interference of weak coherent states with a visibility of up to 91.8% in a Sagnac interferometer over 219.4 km of deployed fiber, pointing to practical deployment of multi-user twin-field quantum key distribution.
