Optical fiber terminal device and optical transmission carrier

Abstract

The optical transmission and reception carrier includes an invisible light transmitter, an invisible light receiver, a visible light transmitter, and an optical fiber connector. The invisible light transmitter emits a first invisible light toward the optical fiber connector and includes a first connector. The invisible light receiver receives a second invisible light from the optical fiber connector and includes a second connector. The visible light transmitter emits visible light toward the optical fiber connector. One of the first connector and the second connector is a flat panel cable.
