Field terminable fiber optic connector assembly
A fiber optic connector assembly includes a connector and a carrier. The connector has first and second ends and a terminated fiber. The fiber defines a first end adjacent the first end of the connector and a second end protruding out of the second end of the connector. A carrier having a connector end and an opposite cable end is engaged with the connector. An alignment structure on the carrier includes a first end, a second end, and a throughhole and also a cutaway extending perpendicularly to and communicating with the throughhole. The fiber is positioned within at least a portion of the throughhole with the second end located within the cutaway. A window is within the cutaway over the second end of the fiber for visually inspecting the alignment of the second end of the fiber with an end of another fiber.
