Abstract
Methods of reducing optical beat interference in a fiber optic network are provided. The optical fiber network may have a plurality of optical network units that communicate with a shared receiver. The optical signals that are transmitted from the optical network units to the receiver may have polarization states that are selected to reduce optical beat interference at the receiver.
