Abstract
A 2-to-1 POF optical coupler, a bi-directional link that employs the coupler, and methods for performing 2-to-1 optical coupling are provided, wherein the 2-to-1 POF optical coupler is configured to provide a carefully-selected amount of cross-sectional overlap at the interface between the end face of a main POF or POF pigtail and the end face of the coupler. The amount of overlap is selected to ensure that optical coupling losses are reduced and optical efficiency is increased in both directions in a bi-directional optical communications links. Consequently, signal integrity is improved, limitations on link length are relaxed, and overall link performance is improved while, at the same time, overall link costs are reduced.
