Optical integrated device and optical time domain reflectometer

Abstract

The present disclosure provides an optical integrated device and an optical time domain reflectometer. The optical integrated device includes: a packaging outer shell, a first collimator, an optical splitting device, a circulator assembly and a second collimator. The optical splitting device is provided close to the first collimator, is used to reflect a part of the detecting light from the first pigtail and couple the part of the detecting light to the third pigtail, and allows the other part of the detecting light to pass through the optical splitting device. The circulator assembly is provided close to the optical splitting device, the circulator assembly is used to couple the detecting light passing through the optical splitting device to the second pigtail, and couple the detecting light returned from the second pigtail to the third pigtail. The optical integrated device integrates the optical splitting device and the circulator assembly to be packaged in one packaging outer shell, the number of components of the optical time domain reflectometer may be reduced, the number of optical fiber fusion joints may be reduced, a space may be saved and performance may be promoted.
