Beschreibung
Zusammenfassung:	A circulator (10) includes a first collimating device (12) and a second collimating device (16) with three external optic fibers (14), (18) & (20) thereon wherein the first fiber (18) and the third fiber (20) are coupled to the second collimating device (16) while the second fiber (14) is coupled to the first collimating device (12). A non-reciprocal section (22) is positioned between the first collimating device (12) and the second collimating device (16). The non-reciprocal section (22) includes a first optic isolator section (24) and a second optic isolator section (26) commonly sandwiching a first light deflecting device (28) therebetween, and a second light deflecting device (30) being positioned between the second optic isolator section (26) and the second collimating device (16).
