A brief dip into the mathematics behind this paper by Ruyong Wang, Yi Zheng, and Aiping Yao, 2004:

In this video, we disregard index of refraction of the fiber optic cable and merely estimate (under classical, pre-Einstein) dynamics what the phase shift for the apparatus should be and why.
Spoiler Alert: It's the speed of the FOG relative to the cable. Working the problem in this way lets us avoid the question of SR vs non-SR and show it works either way
