Disclosed is a low-cost small optical circulator, which is formed by gluing a left polarization beam splitter gluing prism, a half-wave plate, a magneto-optical rotation piece, and a right polarization beam splitter gluing prism having a high reflective film plated on one surface. The left polarization beam splitter gluing prism is formed by gluing a parallelogram prism and a right angle triangular prism. The right polarization beam splitter gluing prism is formed by gluing a parallelogram prism and a right angle triangular prism having a high reflective film plated on one surface. In cooperation with a single fiber collimator, a dual fiber collimator or an optical port assembly, the circulator core can be used for realizing a single-core or two-in-one low-cost small circulator, and the circulator has the advantages of high isolation degree, low cost, and small size. La divulgation concerne un petit circulateur optique à coût modéré qui est formé en collant un prisme de collage de séparateur de faisceau de po
