Optical fiber coupler having male port and female port

摘要

An optical fiber coupler includes a male port and a female port. The male port includes a main body, the male transmission lens and the male receiving lens positioned on the main body, and a male optical wave guide assembly. The male base board includes at least one male optical wave guide. Each male optical wave guide includes a male first alignment portion and a male second alignment portion. The male first alignment portion is optically coupled with one male receiving lens; and a male second alignment portion has a greater width than that of the male first alignment portion. The structure of the female port is similar to the male port.
