UNIVERSAL OPTICAL FIBERS FOR OPTICAL FIBER CONNECTORS

摘要

An optical fiber for use as a stub fiber in an optical fiber connector is disclosed. The optical fiber is configured with a segmented core that includes a single-mode segment with a step-index profile and at least one multimode segment having at least one alpha profile. A connector that employs the stub fiber can connect to both a single mode fiber and a multimode fiber.
